Bootstrap 5 Alpha 3

Our third alpha release has landed with tons of updates to our components, utilities, docs, forms, JavaScript, and more. This is a larger alpha release for us and sets us up for our first beta where we’ll introduce some final breaking changes and features.

We’re trying to move fast and keep the future of the project and the web in general in mind, so this release is an important milestone for us. We’re balancing practical migration from v4 with meaningful changes that reflect the ever-changing front-end community.

We think you’ll love this release, so keep on reading and let us know what you think!

Components

We’ve improved a handful of components in this release, and even dropped one for some new and improved utilities.

New accordion

We’ve dropped the .card based accordion for a brand new .accordion component, solving several bugs in the process. Our new accordion still uses the Collapse JavaScript plugin, but with custom HTML and CSS to support it, it’s better and easier than ever to use.

The new accordion includes Bootstrap Icons as chevron icons indicating state and click-ability. We’ve included support for a flush accordion (add .accordion-flush) to remove the outer borders, allowing for easier placement inside parent elements.

See the PR for extra details on what’s new, or visit the new docs page.

New block buttons

Block buttons are no more in v5—we’ve dropped the .btn-block class for .d-grid and .gap-* utilities. This allows for the same behavior and style, but with much greater control over spacing, alignment, and even responsive layout options.

See the buttons docs page for details.

Docs improvements

We’re always looking for new ways to improve our documentation, and this release is no different. We have a ton of changes big and small.

We’ve added a keyboard shortcut to focus you on the search field. Hit Ctrl + / to trigger it.

We’ve also rewritten the docs sidebar to use actual <button> elements instead of anchors, and improved the focus styling.

Content-wise, we’ve renamed the “Navs” page to “Navs & Tabs” to help folks find our tab JavaScript features better. We’ve also made some style changes, improving the focus styles of heading anchor links and removing text wrapping from code snippets for shorter and easier to read code.

Sass

Three important and helpful changes to our Sass source code:

• We’ve switched to Dart Sass with LibSass being deprecated. We’ve been testing our builds with Dart Sass for a while and decided to make the switch with LibSass being deprecated just a couple of weeks ago. We’re holding on the Sass modules for now.

• The color system which worked with color-level() and $theme-color-interval was removed in favor of a new color system. All lighten() and darken() functions in our codebase are replaced by tint-color() and shade-color(). These functions will mix the color with either white or black instead of changing its lightness by a fixed amount. The scale-color() will either tint or shade a color depending on whether its weight parameter is positive or negative. See #30622 for more details.

• We’ve added a Sass variable for CSS custom property prefixes.

JS

Ahead of some larger and necessary JavaScript changes in Beta 1, we’ve shipped a few updates to our plugins.

• Simplified dropdown’s placement
• Removed redundant polyfills since we dropped IE and Legacy Edge
• Fixed the carousel data-interval bug by checking for data-interval on the first slide
• Removed Manipulator.toggleClass to simplify some code since we only used it one place

Utilities

Utility classes are incredibly powerful in Bootstrap, especially with our new utilities API.

With our first beta, we’ve overhauled our API docs to provide clearer examples and information on adding, modifying, removing, and extending our default utilities.

In addition, we’ve added some new default utilities to make life a little easier:

• Added .d-grid for display: grid
• Added .fs utilities for font-size
• Renamed font-weight utilities to .fw
• Added .rounded-1, .rounded-2, and .rounded-3 for new small, medium, and large border-radius utilities
• Added .overflow-visible and .overflow-scroll utilities

Our next release will also add another powerful feature to our utilities, pseudo-class support!

Forms

Forms have some exciting changes thanks to the addition of floating labels as a fully-fledged form layout option and a new file input.

Floating labels

Floating labels include support for textual inputs, selects, and textareas. We have one limitation with textareas where multiple lines of text can be obscured by the floating label. We’re working on fixes for this, so if you have ideas, please let us know!

New file input

We’ve dropped our custom .form-file class for additional styles on the .form-control class. This means we no longer require additional JavaScript to make our file input styles functional—the new form file is all CSS!

Input group rounded corners

Beyond that, we’ve finally resolved ourselves to adding a new class to fix the rounded corners on input groups when using validation. Add the .has-feedback class to the .input-group to enable validation messages inside input groups without any visual regressions. The good news is this is also being backported to v4 in our next release.

And more

In addition, we’ve made a few other form-related improvements:

• Removed explicit height from most of our form controls.
• Fixed the disabled checkbox toggle buttons
• Added docs examples for disabled .form-control, .form-select, and .form-range elements

Have some form feature requests or improvements we should consider? Please open an issue!

Quality of life

Lastly, across the board we’ve made some minor updates to browser support, Reboot styling, components, and more

• Moved our preferred CDN from BootstrapCDN to jsDelivr
• Dropped support for Legacy Edge (woohoo!)
• Updated to Node.js 14 and PostCSS 8.x
• Removed obsolete prefixes in our CSS
• Added cursor: pointer and heights to color inputs
• Removed background-clip on .btn-close so the background-image is no longer clipped
• Improved sans-serif font selection in Ubuntu
• Spinners now slow down when reduced motion is enabled rather than stopping outright
• Fix inconsistent whitespace in breadcrumbs

See all the changes in the v5 Alpha 3 project board and v5 alpha 3 release changelog. Be sure to read the Migration guide for details on what’s changed since Alpha 2.

Coming in Beta 1

Beta 1 will be a more narrowly focused release and we’re hoping to ship these final breaking changes as part of it.

• RTL! RTL is still coming! The PR is being reviewed by our team would like it to land in Beta 1 to ensure we can get some testing from the community.

• Updating to Popper.js v2. Still on our radar, but moving slower than we anticipated due to some of the differences in the major release. See the PR for details.

• Namespaced data attributes to help keep our functionality clearly separated from your own. See the PR.

• Updated utilities API with pseudo-classes support via a state option. Add any space-separated list of states to get additional utilities for that pseudo-class. See the work-in-progress PR for details.

For a more up to date list of changes, be sure to follow along with the v5 Beta project board.

Bootstrap 4.5.3

We’ve updated Bootstrap 4 with a new patch release to fix some bugs, backport some iterative changes from v5, and more. Enjoy!

As you may already know, we’re alternating between v4 and v5 releases to keep both versions moving in tandem. This helps us close the gap between v4 and v5 and make updating to v5 as easy as possible.

Read on for the highlighted changes.

Changes

Also available in the v4.5.3 release on GitHub.

CSS

• #31653: Add a comment to our escape-svg function to note that data URIs must be quoted.
• #31693: Use the custom-control shadow variable instead of the generic input-focus-box-shadow.
• #31793: Backport some v5 changes (improved th styling in Reboot, custom form field styling when printing, and improvements to .text-break).
  • #29714: Keep custom check, radio, and switch theme when printing.
  • #30781: Reboot’s th updates: Inherit font-weight: bold that comes from user agent stylesheets.
  • #30932: .text-break changes to drop overflow-wrap and use word-wrap once again
  • #31754: Improve versions page rendering (also reversed the order while I was here)
• #31846: Backports the z-index change to .close buttons in dismissible .alerts.

JS

• #31000: Avoid multiple change event trigger in buttons plugin. Not applicable to v5 since our button JS plugin has been mostly replaced with pure CSS.
• #31673: Fix dropdown variable always evaluating to true.
• #31696: Ensure hidePrevented.bs.modal can be prevented.
• #31718: Backports new $dropdown-padding-x variable from v5.

We’ll be back to v5 with our third alpha release coming in a couple of weeks. After that, we’ll ship another v4 update with v4.6.0 that continues the v5 backports and feature development. Please keep the feedback coming on what we can improve, how our releases are performing, and any other suggestions.

Bootstrap 5 Alpha 2

We’re back at it again with a brand new alpha release of Bootstrap 5! Our second alpha has brought some new and improved features, color contrast improvements, improved helpers and utilities, and some documentation design updates.

Check out the latest in the docs at https://v5.getbootstrap.com. Read the release notes for a full list of changes since Alpha 1. Our migration guide has also been updated with a new section for Alpha 2.

Updated docs nav

We’ve cleaned up the navigation in our docs to make things a little easier to use while on a mobile device or a narrow viewport. We’ve redesigned the main navbar to hide links on small devices, and when expanded, those navigation links now have larger tap targets.

Our subnav has also be streamlined to take up a single horizontal bad on mobile, giving more space for documentation. We’ve also differentiated the expanding and collapsing menu icons between the two navs.

Together this should make it a little faster and easier to navigate our docs, and serve as a fun little demo for others.

Dark carousel

Add .carousel-dark to any .carousel to switch from the default white text, controls, and indicators to black.

Values are configurable via Sass variables. To save on filesize, we’re using a CSS filter to invert out SVGs for the carouse controls. Pretty neat if you ask us!

Dark dropdowns

For the first time since Bootstrap v1 nearly nine years ago, we have dark dropdown menus! Add .dropdown-menu-dark to any dropdown menu to change the appearance. Dark dropdowns are opt-in, so you’ll need to add the class as you go.

We’d like to revisit some of this later in v5 with minor releases that advance dark mode throughout the entire project. Until then, enjoy the new classes!

Redesigned close button

Our close button has been renamed, redesigned, new focus state, and a new color option.

We’ve renamed the class from the rather generic .close to .btn-close. In addition, we’ve dropped the use of × in our HTML for an SVG background-image via CSS. With updated styling all around, the close button has a clearer focus state and even an all-new white variant (also powered by a CSS filter).

Position utilities

Thanks to our contributors, we’ve added new directional positioning utilities. Quickly position an element with our new top, right, bottom, and left utilities with support for 0, 50%, and 100% by default.

Combine with new translate utilities to center elements on an edge or corner, too! The new utilities are configurable and extensible thanks to the utilities API and some smart Sass map defaults.

More highlights

Some other incremental changes to a few components and changes include:

• Container horizontal padding has been updated to match the row gutters variables and values.
• Checkboxes and radios downsized to 1em from 1.25em for improved font scaling support.
• Improved colors with green and cyan getting new values, plus higher contrast ratios all around.
• Improved toast styling, now without overflow: hidden.
• Badge padding increased a smidge.
• Revamped “responsive embed” helpers, now called ratio helpers. New class names across the board, more flexible styles, and a new CSS variable for custom dynamic and responsive ratios.
• Screen reader classes are now “visually hidden” classes.
• New .border-width utility.

See all the changes in the v5 Alpha 2 project board and be sure to read the Migration guide for details on what’s changed since Alpha 1.

Coming in Alpha 3

We’ve pushed some additional breaking changes and important component updates to Alpha 3. To give you a heads up, here are some important upcoming moves:

• Offcanvas support is coming thanks to new side modals!
• We’re revamping the input group component, dropping support for quite a few variations. It’s too complex, supports too many variations, and has had the most annoying border-radius bug through all of v4. (I’m so sorry about that!)
• We’re upgrading floating labels from a docs Example into a fully fledge form layout option, with support for textual inputs, selects, and textareas.
• We’re adding font-size utilities and updating our font-weight utilities.
• RTL is still coming! The PR is being reviewed by our team and we’re hoping to land it in Alpha 3 so we can get some folks testing with it.

For a more up to date list of changes, be sure to follow along with the v5 Alpha 3 project board. More docs improvements are planned with the potential for more breaking changes as well. From there it’s onto final breaking changes in Beta 3.

Release expectations

We’ll be alternating releases across v4 and v5 to keep the momentum up. We’re shipping v4.5.3 next and then moving right back to v5 for Alpha 3. We’ve noted our intended release schedule in our release repo. We’ll also keep updating that repo’s readme as we go.

Bootstrap Icons v1.0.0

After five alphas over the last nine months, Bootstrap Icons has officially gone stable with our v1.0.0 release! We’re now over 1,100 icons and are on track to add hundreds more in our upcoming minor releases. This has been a labor of love and I’m thrilled to ship this latest update.

Since our fifth alpha two months ago, over a third of our icons have been redrawn as we fine-tuned paths and shapes. Much of the redrawing and improvements here came as preparation for an icon font, but regrettably that’s been pushed back to a v1.1.0 release as the tooling for generating fonts from SVGs has proven more difficult to get right.

1,100+ icons

Our first alpha had just over 200 icons, and here we are with 1,120 icons in our first stable release. And we’ll only have more in future releases.

Usage

If you’ve been following along these last several months, you’ll know Bootstrap icons are SVG based. That makes them super easy to import, customize, and extend—no matter the project. While they’re part of the Bootstrap family, they can be used anywhere. That’s because they’re released under the MIT license.

Use them as embedded SVGs, as external assets with <img> tags, as an SVG sprite, or even embedded in your CSS. Head to the docs to learn more.

Install

To get started, install via npm:

npm i bootstrap-icons

You can also download the release from GitHub, or download just the SVGs (without the rest of the repository files).

Figma

For the Figma users out there, you can also snag the icons from Figma.

Up next

We’ll revisit the icon font hopefully in time for our next v1.1.0 release. In addition, there are already another 200+ icons drawn and plans for even more after. We’ll continue to fine-tune and iterate on these icons, so keep the feedback and requests coming.
