<p>It's a common practice to apply CSS to a page that styles elements such that they are consistent across all browsers. We offer two of the most popular choices: <a href="https://necolas.github.io/normalize.css/" target="_blank" rel="noopener">normalize.css</a> and a <a href="http://meyerweb.com/eric/tools/css/reset/" target="_blank" rel="noopener">reset</a>. Or, choose <b>Neither</b> and nothing will be applied.</p>

<p>To get the best cross-browser support, it is a common practice to apply vendor prefixes to CSS properties and values that require them to work. For instance <code>-webkit-</code> or <code>-moz-</code>.</p>
<p>We offer two popular choices: <a href="https://github.com/postcss/autoprefixer" target="blank" rel="noopener">Autoprefixer</a> (which processes your CSS server-side) and <a href="https://leaverou.github.io/prefixfree/" target="_blank" rel="noopener">-prefix-free</a> (which applies prefixes via a script, client-side).</p>
