-Flexbox support has finally come to Bootstrap. 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 via Grunt.
-
-## 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. [Head to the download page]({{ site.baseurl }}/getting-started/download) for more information.
-
-## Browser support
-
-Enabling flexbox means **reduced browser and device support:**
-
-- Internet Explorer 9 and below do not support flexbox.
-- Internet Explorer 10 has a few known quirks (see the "Known issues" tab in [Can I use...](http://caniuse.com/#feat=flexbox)), requires using a prefix, and only supports the syntax from the old 2012 version of the spec.

-Please be extra conscious of your user base when enabling flexbox in your project. Visit [Can I use...](http://caniuse.com/#feat=flexbox) for details on browser support of flexbox.
