The Figma file is now published to the Figma Community! It’s the same Bootstrap Icons Figma file you’ve seen from previous releases, just a little more accessible to those using the app.
It’s the biggest release since v5 itself—Bootstrap v5.2.0-beta1 is here! This release features redesigned docs, CSS variables for all our components, responsive offcanvas, new helpers and utilities, refined buttons and inputs, and lots of improvements under the hood.
Given the size of the update and time since our last release, we’re doing something different and shipping it as a beta first. Keep reading for details.
Why so long?
I want to start by acknowledging the time it’s taken to ship a new release. As an open source maintainer, I’m constantly worried about not doing or being good enough of a developer for my projects. Pair that with a distributed team all working through this pandemic and me having a heart attack, we’ve all needed some down time. I managed to put together a Bootstrap Icons release with what energy I had before needing another break. The rest of the team has also needed some well deserved down time.
I ask that you all please take some time to send some appreciation and support to your favorite open source maintainers. Everyone could use a little more love in this work.
All that said, we’re shipping v5.2.0-beta1 first since it’s been so long—we’d love your help testing things out. We’ll follow up with a stable release as soon as possible.
Okay, now onto the good parts!
Redesigned docs
Another release, another docs refresh! From the get go, you’ll notice our Bootstrap Purple™ is much more vibrant now, making everything feel brand new. We’ve rewritten our entire homepage to better show off all the awesome features of Bootstrap.
Stepping into the actual docs, you’ll notice quite a few changes. We’ve streamlined our navbar, done away with our subnav, and changed the sidebar to always show every page link for greater discoverability. Show above is also our refreshed quick start guide, which is now a step-by-step instructional guide for using Bootstrap via CDN.
The refreshed navbar also has a long-awaited new version picker for v5.2.0 and beyond. From any page, click the version and see options to navigate to previous minor releases of that same page. When a page doesn’t exist in an older release, you’ll see a disabled version in the dropdown. We currently have no plans to link pages across major versions.
The docs search is now powered by the latest version of Algolia’s DocSearch, bringing an improved design that even shows your most recent searches.
Design tweaks
To coincide with our docs redesign, we’ve given our buttons and inputs a slight refresh with some refined border-radius values. It’s a small change, but a welcomed refresh to keep things modern and fresh. Here’s a look at the before and after of our buttons:
With this release, all our components now include CSS variables to enable real-time customization, easier theming, and (soon) color mode support starting with dark mode. Every component page has been updated to include a reference guide of the relevant CSS variables. Take for example our buttons:
Values for virtually every CSS variables are assigned via Sass variable, so customization via CSS and Sass are both well supported. Also included for several components are examples of customizing via CSS variables.
Check out all our components to see how you can customize them to your liking.
New _maps.scss
Bootstrap v5.2.0-beta1 introduces a new Sass file with _maps.scss that pulls out several Sass maps from _variables.scss to fix an issue where updates to an original map were not applied to secondary maps that extend it. It’s not ideal, but it resolves a longstanding issue for folks when working with customized maps.
For example, updates to $theme-colors were not being applied to other maps that relied on $theme-colors (like the $utilities-colors and more), which created broken customization workflows. To summarize the problem, Sass has a limitation where once a default variable or map has been used, it cannot be updated. There’s a similar shortcoming with CSS variables when they’re used to compose other CSS variables.
This is also why variable customizations in Bootstrap have to come after @import "functions";, but before @import "variables"; and the rest of our import stack. The same applies to Sass maps—you must override the defaults before they get used. The following maps have been moved to the new _maps.scss:
$theme-colors-rgb
$utilities-colors
$utilities-text
$utilities-text-colors
$utilities-bg
$utilities-bg-colors
$negative-spacers
$gutters
Your custom Bootstrap CSS builds should now look like this with a separate maps import.
// Functions come first
@import "functions";
// Optional variable overrides here
+ $custom-color: #df711b;
+ $custom-theme-colors: (
+ "custom": $custom-color
+ );
// Variables come next
@import "variables";
+ // Optional Sass map overrides here
+ $theme-colors: map-merge($theme-colors, $custom-theme-colors);
+
+ // Followed by our default maps
+ @import "maps";
+
// Rest of our imports
@import "mixins";
@import "utilities";
@import "root";
@import "reboot";
// etc
New helpers and utilities
We’re continuing to invest in our helpers and utilities to make it easier to quickly build and modify custom components.
Added new .text-bg-{color} helpers. Instead of setting individual .text-* and .bg-* utilities, you can now use the .text-bg-* helpers to set a background-color with contrasting foreground color.
Expanded border-radius utilities to include two new sizes, .rounded-4 and .rounded-5, for more options.
Expect more improvements here as v5’s development continues.
Responsive offcanvas
Our Offcanvas component now has responsive variations. The original .offcanvas class remains unchanged—it hides content across all viewports. To make it responsive, change that .offcanvas class to any .offcanvas-{sm|md|lg|xl|xxl} class.
And tons more!
Introduced new $enable-container-classes option. — Now when opting into the experimental CSS Grid layout, .container-* classes will still be compiled, unless this option is set to false. Containers also now keep their gutter values.
Thicker table dividers are now opt-in. — We’ve removed the thicker and more difficult to override border between table groups and moved it to an optional class you can apply, .table-group-divider. See the table docs for an example.
Scrollspy has been rewritten to use the Intersection Observer API, which means you no longer need relative parent wrappers, deprecates offset config, and more. Look for your Scrollspy implementations to be more accurate and consistent in their nav highlighting.
Added .form-check-reverse modifier to flip the order of labels and associated checkboxes/radios.
Added striped columns support to tables via the new .table-striped-columns class.
Much of the work we’ve done in v5.2.0-beta1 has been in support of adding dark mode to Bootstrap. Yes, it’s finally coming in our next minor release!
We’re adding tons of new global CSS variables, cleaning up docs styles, and better supporting overall customization. Some details and topics being worked on for dark mode:
Do we provide a JS plugin for toggling color modes? Right now we’re just building custom functionality for our docs.
Our current implementation is being built with data-theme selectors which allows explicit color mode switching (via user control vs and system preference) and custom color modes beyond light and dark.
We’re adding quite a few new colors outside $theme-colors to improve subtle UI customization. These are being implemented via :root and [data-theme="{theme}"] selectors for global use.
Bootstrap Icons v1.8.0 is here with over 140 new icons, including dozens of new heart icons ready for Valentine’s Day and dozens of filetype icons. We’re now at almost 1,700 icons and is once again our second largest release. Keep reading to see what’s new.
140+ new icons
Perfect for Valentine’s Day or any other time you need to show a little heart, there are dozens of icons to choose from.
Want to visually show the extensions of your files? There are tons of new options for programming languages, audio and video, images, and more.
Elsewhere we’ve expanded a number of other categories of icons. There are some new medical icons (more are planned), lots of new clipboard icons, additional tools, and more.

Bootstrap v4.6.1 has finally arrived! Biggest change here is a re-implementation of our Sass division functions and updates from v5, as well as some accessibility improvements and general bug fixes.
We’ll be flipping back to v5 development after this release, focusing on v5.2.0 with some additional updates to using more CSS variables and other awesome features. Sometime after that, we hope to ship a v4.7.0 release with some additional backported features and improvements to v4.
Please keep the feedback coming on what we can improve, how our releases are performing, and any other suggestions.
Bootstrap Icons v1.6.0 adds over 30 new icons, adds official Composer support, includes a new .scss stylesheet for the icon font, plus some other enhancements and bug fixes. Keep reading to see what’s new!
1,400+ icons
We’ve officially passed 1,400 glyphs in Bootstrap Icons with this release—woohoo! Seems utterly insane to me that the project has come this far and there are still so many more icons to include.
We have a few dozen new and updated icons in this release, including:
New brand icons for Apple, Behance, Dribbble, Line, Medium, Microsoft, PayPal, Pinterest, Signal, Snapchat, Spotify, Stack Overflow, Strava, Vimeo, Windows, and WordPress
Two new easel variations
New fingerprint icon
New magic stick
New people variations for rolodex, workspace, and video chat
New webcam icons
New radioactive icon
New fan icon
New hypnotize icon
New yin yang icon
New activity/pulse icon
Updated large dash, plus, slash, x, i, ?, !, and check icons to have a thinner stroke that better matches other icons
Updated lamp icons
Updated graph-up and graph-down icons, with the previous ones being renamed to graph-up-arrow and graph-down-arrow
New features
We’ve added a handful of new features and enhancements to how you can use Bootstrap Icons in this release:
Added Composer support with automatic publishing to Packagist. See the official package for more information.
Added new bootstrap-icons.scss stylesheet for the icon font. This includes font name and path variables, plus a Sass map of icon names and unicode values.
Added new .bi CSS selector to the icon font ruleset (in addition to the attribute selectors we had through v1.5.0) to allow for easier @extending of icon styles. This has also been reflected in the new .scss stylesheet.
Our next minor release will continue to see improvements to our icon permalink pages, adding more options for copying and pasting our icons. If you have other suggestions, please don’t hesitate to open a new issue!
Bug fixes
We’ve fixed a few glitches with existing icons in this release:
droplet-fill now renders correctly thanks to an updated fill rule
lamp and lamp-fill now look more like lamps and less like toilets 😅
coin now renders correctly thanks to an updated fill rule
cloud now renders correctly thanks to an updated fill rule
textarea-resize is no longer incorrectly placed in the viewBox

The Figma file is now published to the Figma Community! It’s the same Bootstrap Icons Figma file you’ve seen from previous releases, just a little more accessible to those using the app.
Bootstrap v5.1.2 is here with a handful of improvements across our components, plus a fix for an issue in another project that prevented our Sass from compiling properly. Keep reading for the highlights.
Highlights
Temporarily patched a postcss-values-parser issue by rearranging our calc() functions that use negative numbers. This should restore the ability to import and compile Bootstrap’s Sass in create-react-app.
Added border-radius sizes to small and large .form-selects
Added align-self: center to buttons for improved rendering in flex containers
Fixed Collapse regression that prevented toggling between sibling children
Updated JS Sanitizer to add sms in the SAFE_URL_PATTERN
Improved docs around .img-fluid
Added role="switch" to our form switches in our docs
Implemented GitHub Issue forms to replace our previous issue templates.
Up next
Up next is our v5.2.0 release, adding more utility improvements and fixing an issue with how Sass handles re-assigned maps and variables. Alongside that, we’ll be shipping an update to v4 soon as well.
Bootstrap v5.1.1 has landed with a handful of bug fixes and documentation improvements. Following this release, we’ll be shipping another bugfix and docs update before moving onto additional new features. Keep reading for the highlights.
Highlights
Fixed broken .bg-body utility. This was caused by the same --body-rgb CSS variable for both text and background. --body-rgb is now split into --body-color-rgb and --body-bg-rgb for proper usage. While this could be considered a breaking change, the current implementation was outright broken, so we’ve chosen to address this head-on.
All CSS dist builds now include _root.scss and all our :root-level CSS variables. The goal here is consistency across the distribution files so that no matter what CSS build you use, you have the same level of customization potential.
We’ve had a number of Visual Studio users mention that Sass compiling for Bootstrap 5.1.0 is broken when using the Web Compiler extension. This extension hasn’t been updated in more than five years, so we recommend moving to a newer alternative. Some users mentioned the Sass Compiler extension as a successful alternative. If you have additional recommendations, please leave a comment to share.
Ten years ago today, we shipped the first release of Bootstrap. Releasing it on GitHub was my first real plunge into open source—what an introduction! Here we are a decade later with one of the most widely used open source projects and frontend toolkits on the web. Happy birthday, Bootstrap—what a ride!
While numbers certainly don’t tell the whole story, Bootstrap has reached some incredible milestones over the past decade. Here are some highlights:
Over 2.5 billion pageviews for our docs. That’s more than 685,000 a day.
394,000,000 npm downloads since 2015—over 131 million of which were in 2020 alone. That’s 180,000 a day over the last six years.
Over 21,100 commits on GitHub with nearly 35,000 issues and pull requests
Hidden in all those numbers are millions and millions of people that interact with Bootstrap just by visiting the sites and apps built with it. It’s still mind-blowing to see what’s been built with it after over the years, especially with how it all started.
Back in early 2011, the two of us were just a couple of nerds working at Twitter—Jacob was an engineer working on internal tools, me a product designer working on ads. Our paths crossed when the project I was working on needed to have its own internal tools app built for managing Twitter ad campaigns. Over a few months, we started working more and more together before ultimately deciding to release our project to the world.
Here we are 10 years later, still just a handful of nerds doing what we love, contributing to open source, and having an impact on people’s lives through our work. Bootstrap continues to be a passion project for me, from major rewrites to new features and from a growing icon library to a full-blown marketplace. It’s been an incredible journey, and one that’s still going strong thanks to the community’s love and the support of a small group of maintainers over the years.
The maintainers and contributors deserve the utmost thanks and appreciation. Please join me in thanking them—and every other open source maintainer!—whenever and however frequently you can. While this list can never fully represent all the contributions made to Bootstrap, I want to give a special shoutout to maintainers past and present, and some of the most prolific contributors.
Thank you again, folks. And to everyone who has used Bootstrap over the years, thank you for making a decade of building with Bootstrap possible. Cheers to whatever comes next, and see you soon for our next release.
The first minor release of Bootstrap 5 is here! v5.1.0 has arrived and is packed with exciting new features and improvements. There’s experimental support for CSS Grid, offcanvas in the navbar, a new placeholders component, horizontal collapse support, new helpers, new CSS variables in our utilities, refactored JavaScript, and more.
We’ve added an experimental version of a new CSS Grid as an opt-in replacement to our default grid system. To enable it, disable the default grid, by setting $enable-grid-classes: false and enable the CSS Grid by setting $enable-cssgrid: true. Once recompiled, you’ll be able to switch to the new classes. Our new CSS Grid docs page has all the details and some helpful examples to get you started.
Shipping CSS Grid support as experimental allows us to play with things a bit without breaking backward compatibility for folks. Please help us out by testing it and sharing feedback. We expect it to go stable for widespread use in a future minor release.
We’ve expanded our .navbar-expand-* classes (see what we did there?) to include support for offcanvases inside the navbar. Wrap your navbar elements with the appropriate offcanvas HTML, point your navbar toggler button to the offcanvas, and voila.
There’s a new component in town with placeholders, a way to provide temporary blocks in lieu of real content to help indicate that something is still loading in your site or app. Our first iteration here aims to only provide the HTML and CSS—it’s up to you to implement these placeholders with whatever custom code you might need.
Consider the basic Bootstrap card component shown above.
<divclass="card"><imgsrc="..."class="card-img-top"alt="..."><divclass="card-body"><h5class="card-title">Card title</h5><pclass="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p><ahref="#"class="btn btn-primary">Go somewhere</a></div></div>
Here it is rebuilt with glowing placeholder bars to indicate something is still loading.
Hot damn, we’ve finally added official support for horizontally collapsing! The collapse plugin has been able to detect width vs height for some time (even in v4), but we never had a working example in our docs until now. Add the .collapse-horizontal modifier class to transition the width instead of height and set a width on the immediate child element.
<buttonclass="btn btn-primary"type="button"data-bs-toggle="collapse"data-bs-target="#collapseWidthExample"aria-expanded="false"aria-controls="collapseWidthExample"> Toggle width collapse
</button><divstyle="min-height: 120px;"><divclass="collapse collapse-horizontal"id="collapseWidthExample"><divclass="card card-body"style="width: 300px;"> This is some placeholder content for a horizontal collapse. It's hidden by default and shown when triggered.
</div></div></div>
Heads up! You may need some min-height or height to avoid excessive browser repainting, as we’ve included in our demo above.
Stack and vertical rule helpers
While utilities get most of the spotlight these days, helpers are still incredibly useful. Our newest helpers are called stacks and they’re shortcuts for vertical and horizontal stacks of elements. They’re inspired by the open source Pylon project, which was in turn inspired by iOS’s stacks. Right now, stacks aren’t responsive, but that can easily change with your feedback.
To create a vertical stack, wrap a series of elements in .vstack. Use .gap-* utilities on the parent (or set individual margin utilities) to quickly space elements.
To support these stacks, we’ve also added an additional new helper—.vr, or vertical rule. HTML has had native <hr> elements for the longest time to create horizontal rules, but never anything for vertical rules. The new .vr helper works great in horizontal stacks and other situations where borders are a little trickier.
<divclass="hstack gap-3"><inputclass="form-control me-auto"type="text"placeholder="Add your item here..."><buttontype="button"class="btn btn-secondary">Submit</button><divclass="vr"></div><buttontype="button"class="btn btn-outline-danger">Reset</button></div>
We’ve expanded our :root CSS variables to include our gray color palette, new <body> variables, and new RGB variables for our theme colors. The grayscale colors join our existing color and theme color variables to complete the set of globally available CSS colors. As the development of v5 progresses, these variables will be used more and more in our components to better enable global theming.
Speaking of, our new <body> CSS variables now control the styling of the <body>. This is what you’ll find in the compiled CSS:
Like all our other :root CSS variables, the values for these are generated from our Sass variables. That means that no matter how you customize Bootstrap—via Sass or CSS variables—you haven’t lost any functionality or convenience.
Our new RGB values are built to help us make better use of CSS variables across the entire project. To start, our background-color and color utilities have been updated to use these new RGB values for real-time customization without recompiling Sass and on-the-fly transparency for any background or text color.
Here’s how our .bg-* and .text-* color utilities look now once compiled:
We use an RGB version of each color’s CSS variable and attach a second CSS variable, --bs-text-opacity or --bs-bg-opacity, for the alpha transparency (with a default value 1 thanks to a local CSS variable in the ruleset). That means anytime you use .text-primary now, your computed color value is rgba(13, 110, 253, 1). The local CSS variable inside each .text-* class helps avoid inheritance issues when nesting instances of these classes.
To support these changes, we’ve added some new .text-opacity-* and .bg-opacity-* utilities. Choose from a predefined set (which you can modify in the utilities API) of classes to quickly change the local CSS variable when a given .text-* or .bg-* utility is used. For example:
<divclass="text-primary">This is default primary text</div><divclass="text-primary text-opacity-75">This is 75% opacity primary text</div><divclass="text-primary text-opacity-50">This is 50% opacity primary text</div><divclass="text-primary text-opacity-25">This is 25% opacity primary text</div>
We expect this approach to make its way to border utilities next. Have more CSS variables you’d like to see added? Share your thoughts on a new issue on GitHub. Head to the color utilities or background utilities docs to learn more.
Four new examples
We’ve expanded on our component examples with four new examples that customize some of our core components and implement common patterns. Here’s what’s new:
We’ve variablized the class name for our backdrops that are used across our modal and offcanvas components. This comes with a new class for the offcanvas backdrop, .offcanvas-backdrop, and perhaps more importantly, some updated z-index values.
Previously, there was a single offcanvas z-index between the modal and modal backdrop z-indexs, due to offcanvas sharing the modal’s backdrop.
// Before v5.1.0
$zindex-modal-backdrop:1040!default;$zindex-offcanvas:1050!default;$zindex-modal:1060!default;
We’ve changed this to allow offcanvases and modals to work together better with separate z-index values for offcanvas, the offcanvas backdrop, modal, and the modal backdrop.
// After v5.1.0
$zindex-offcanvas-backdrop:1040!default;$zindex-offcanvas:1045!default;$zindex-modal-backdrop:1050!default;$zindex-modal:1055!default;
Unless you’ve modified the offcanvas component or its Sass variables, there should be no breaking changes for you.
And more!
There’s a lot more in this release that we didn’t include in the highlights above:
Reverted the ability for .col-* classes to override .row-cols-* as it caused some breaking bugs in our layouts. We’ll revisit and restore it when we can engineer it in a more scalable and easy to maintain way.
Added new .opacity-* utilities (with 0, .25, .5, .75, and 1 as default values).
Updated several JavaScript plugins with some major cleanups—alerts, collapse, dropdowns, popovers, and tooltips.
Plugins now accept arguments of different types in the getInstance method.
Added new Sass maps for all our colors, as well as a new map-merge-multiple() function to combine Sass maps.
Updated data-dismiss on modals so that it can be outside of a modal using bs-target.
Updated toasts to change show timings and classes to keep toast display: none by default.
Added Shift + Tab keyboard support to modal and offcanvas components.
Renamed Build Tools page to Contribute to better communicate its purpose.
Fixed Manipulator.offset() in Scrollspy to improve scroll position detection.
