Please first read the issue guidelines and search for existing and closed issues. If your problem or idea is not addressed yet, please open a new issue. Documentation Bootstrap’s documentation, included in this repo in the root directory, is built with Astro and publicly hosted on GitHub Pages at https://getbootstrap.com/. The docs may also be run locally. Documentation search is powered by Pagefind. Running documentation locally Run npm install to install the Node.js dependencies, including Astro (the site builder). Run npm run test (or a specific npm script) to rebuild distributed CSS and JavaScript files, as well as our docs assets. From the root /bootstrap directory, run npm run docs-serve in the command line. Open http://localhost:9001 in your browser, and voilà. Learn more about using Astro by reading its documentation. Documentation for previous releases You can find all our previous releases docs on https://getbootstrap.com/docs/versions/. Previous releases and their documentation are also available for download. Contributing Please read through our contributing guidelines. Included are directions for opening issues, coding standards, and notes on development. Moreover, if your pull request contains JavaScript patches or features, you must include relevant unit tests. All HTML and CSS should conform to the Code Guide, maintained by Mark Otto.

Ask questions and explore our GitHub Discussions. Discuss, ask questions, and more on the community Discord or Bootstrap subreddit. Chat with fellow Bootstrappers in IRC. On the irc.libera.chat server, in the #bootstrap channel. Implementation help may be found at Stack Overflow (tagged bootstrap-5). Developers should use the keyword bootstrap on packages which modify or add to the functionality of Bootstrap when distributing through npm or similar delivery mechanisms for maximum discoverability. Versioning For transparency into our release cycle and in striving to maintain backward compatibility, Bootstrap is maintained under the Semantic Versioning guidelines. Sometimes we screw up, but we adhere to those rules whenever possible. See the Releases section of our GitHub project for changelogs for each release version of Bootstrap. Release announcement posts on the official Bootstrap blog contain summaries of the most noteworthy changes made in each release.

Why bother with this category? The code exercising it is buggy either way, regardless of whether the behaviour is specified or not, and having a fixed definition may constrain implementations and negatively impact performance. And if that "erroneous" definition comes with stability guarantees, then you might not even bother calling it "erroneous" at all, because then it's going to be as toothless as declaring any given JavaScript syntax to be "improper": https://github.com/twbs/bootstrap/issues/3057#issuecomment-5...

The CSS Media Queries Level 4 spec actually includes fractional pixel values as part of the examples for browsers which do not yet support the range syntax: https://www.w3.org/TR/mediaqueries-4/#mq-min-max > One approach to work around this problem is to increase the precision of the values used for the comparison. Using the example above, changing the second comparison value to 320.01px significantly reduces the change that a viewport width on a device would fall between the cracks. The .02/.98 values might seem strange, but many popular libraries use these offsets (including Bootstrap: https://github.com/twbs/bootstrap/blob/main/scss/mixins/_bre...). The way I tend to work with media queries is not writing them directly but rather use a mixin (when using SCSS) or a media function (CSS-in-JS). That way, this weird quirk can be documented

just once in an application, leaving anyone curious enough with the explanation. There tends to be an 'upTo(breakpoint)' function which is an exclusive range, and a 'from(breakpoint)' which is inclusive.

I'm very excited to see this, specifically the Scrollspy refactor [0]. During COVID lockdown, without anything better to do, I went down a rabbit hole debugging some wonky scroll behavior. A bunch of other people had encountered the same issue over the years, but it never was a top priority. I did some research and discovered the Intersection Observer API, which seemed like a perfect fit for this use case. I hacked up a basic implementation[1], asked for some feedback, and promptly forgot about it. I was super stoked to see someone else pick up the idea and run with it, doing a much better job than I could have. Open source is fun!

I created this tool when writing a blog post on how to use Airtable as a database for a Jekyll website. Personally, I don't like tutorials that build to-do apps (or now, Wordle clones) as I think they are often detached from real world and thus tend to skip important topics. So I decided to build something real that I myself might end up using as a developer. The demo is now live and it tells you the version numbers for a limited set of things (like top 10 GitHub repositories, plus a few other things). Posting it here so that I can get some feedback from other developers. If others also find this useful, I will continue the work. Here's my pitch for why it might be useful: 1. It's a fast way to learn what's the current version of something. If you go to the home page and start typing, you will get it in 2 actions (given the thing you're a

fter is in my database). If you type something like https://up-to.date/react in the browser, it now becomes a single-step process. 2. Apart from being fast, this has a potential to prevent mistakes. Many developers trust Google or GitHub as the source of truth on these matters and will not look in other places. But that could lead to mistakes. Some examples of wrong answers I am getting today (May 5, 2022): - Bootstrap: if you go to https://github.com/twbs/bootstrap, you will think that Bootstrap's current version is 4.6.1, but if you then go to https://getbootstrap.com, you will know that it's actually 5.1.3 - Rails: if you google Ruby on Rails, the special card on the right will tell you the latest version is 7.0.2.3, but according to https://rubyonrails.org, it's now 7.0.2.4 already One other thing I want to mention: Clicking search results on the homepage takes you to a dedicated page. There, you will see an email signup form. I put it there in order to see actual interest: if people sign up, that's the best indicator for me that I should continue working on this project. But I am not asking you to enter your email in that form, only do it if you really wish to get updates on new releases. Also, this is a static website so it uses a 3rd party tool for capturing emails. You guessed it right, that tool is also built by me.

A simple function is to calculate whether the total of each RGB channel reaches a certain threshold, with different weights given to each channel. For an example, see the YIQ contrast function used by Bootstrap v4 [0]. WCAG defines their own algorithm for calculating the contrast between two colours to ensure good accessibility [1][2]. Bootstrap v5 uses this [3]. [0] https://github.com/twbs/bootstrap/blob/v4.6.1/scss/_function...
