Opt-in to the new CSS layout styles with the flick of a variable or the swap of a stylesheet. - -## Contents - -* Will be replaced with the ToC, excluding the "Contents" header -{:toc} - -## What's included - -Flexbox support is available for a number of Bootstrap's components: - -- The entire grid system (mixins and predefined classes), which switch from `float`s to `display: flex;`. -- Input groups, which move from `display: table;` to `display: flex;`. -- The media component moves from `display: table;` and a number of hacky styles to a simple `display: flex;`. - -Vendor prefixes are provided in our compiled CSS with [Autoprefixer](https://github.com/postcss/autoprefixer) via Grunt. Some bugs in IE10-11's Flexbox implementation are worked around via [postcss-flexbugs-fixes](https://github.com/luisrudge/postcss-flexbugs-fixes). - -## Why flexbox? - -In a nutshell, flexbox provides simpler and more flexible layout options in CSS. More specifically, it provides: - -- Easy vertical alignment of content within a parent element. -- Easy reordering of content across devices and screen resolutions with the help of media queries. -- Easy CSS-only equal height columns for your grid-based layouts. - -All these things are possible outside flexbox, but typically require extra hacks and workarounds to do right. - -## How it works - -If you're familiar with modifying variables in Sass—or any other CSS preprocessor—you'll be right at home to move into flexbox mode. - -1. Open the `_variables.scss` file and find the `$enable-flex` variable. -2. Change it from `false` to `true`. -3. Recompile, and done! - -Alternatively, if you don't need the source Sass files, you may swap the default Bootstrap compiled CSS with the compiled flexbox variation.
