## Overview and limitations
The overall accessibility of any project built with Bootstrap depends in large part on the author's markup, additional styling, and scripting they've included. However, provided that these have been implemented correctly, it should be perfectly possible to create web sites and applications with Bootstrap that fulfill [<abbr title="Web Content Accessibility Guidelines">WCAG</abbr> 2.0](https://www.w3.org/TR/WCAG20/) (A/AA/AAA), [Section 508](https://www.section508.gov/) and similar accessibility standards and requirements.

Copy and paste relevant lines from there into the `_custom.scss` file, modify the values, and recompile your Sass to change our default values. **Be sure to remove the `!default` flag from override values.**

For Bootstrap to compile, make sure you install and use the required loaders: [sass-loader](https://github.com/webpack-contrib/sass-loader), [postcss-loader](https://github.com/postcss/postcss-loader) with [Autoprefixer](https://github.com/postcss/autoprefixer#webpack) and [postcss-flexbugs-fixes](https://github.com/luisrudge/postcss-flexbugs-fixes). With minimal setup, your webpack config should include this rule or similar:
