## 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 websites and applications with Bootstrap that fulfill [<abbr title="Web Content Accessibility Guidelines">WCAG</abbr> 2.1](https://www.w3.org/TR/WCAG/) (A/AA/AAA), [Section 508](https://www.section508.gov/), and similar accessibility standards and requirements.

### Color contrast
Some combinations of colors that currently make up Bootstrap's default palette—used throughout the framework for things such as button variations, alert variations, form validation indicators—may lead to *insufficient* color contrast (below the recommended [WCAG 2.1 text color contrast ratio of 4.5:1](https://www.w3.org/TR/WCAG/#contrast-minimum) and the [WCAG 2.1 non-text color contrast ratio of 3:1](https://www.w3.org/TR/WCAG/#non-text-contrast)), particularly when used against a light background. Authors are encouraged to test their specific uses of color and, where necessary, manually modify/extend these default colors to ensure adequate color contrast ratios.
