This is normally the safest way to include variables.</p> +<p>As for the variables themselves, you declare that they are variables using the <code>--</code> tags, followed by the variable’s name and it’s property. Pretty simple stuff, right?</p> +<p>Now let’s use those variables:</p> +<pre><code>.header { + border: 1px solid var(--base-color); +} + +.main-container { + background-color: var(--base-color); + color: var(--text-color); +} +</code></pre> +<p>That’s it! It’s also good to know that CSS variables have pretty decent <a href="https://caniuse.com/#feat=css-variables">browser support</a> (who likes IE11 anyway).</p> +<h3 id="why-not-just-use-a-preprocessor">Why not just use a preprocessor?</h3> +<p>I’m a pretty big fan of Sass and Stylus, but sometimes it’s refreshing to just use vanilla CSS for certain projects. Most preprocessors have had the ability to use variables and mixins for a while, but I prefer to avoid build scripts when not absolutely necessary.</p> +<p>Get out there and have fun with some variables!</p> +<footer role="contentinfo"> + <h2>Menu Navigation</h2> + <ul id="menu"> + <li><a href="/">Home</a></li> + <li><a href="/projects">Projects</a></li> + <li><a href="/uses">Uses</a></li> + <li><a href="/wiki">Wiki</a></li> + <li><a href="/resume">Resume</a></li> + <li><a href="/colophon">Colophon</a></li> + <li><a href="/now">Now</a></li> + <li><a href="/donate">Donate</a></li> + <li><a href="/atom.xml">RSS</a></li> + <li><a href="#top">↑ Top of the page</a></li> + </ul> + <small> + Built with <a href="https://barf.btxx.org">barf</a>. <br> + Feeds: <a href="/atom.xml">Atom</a> & <a href="/rss.xml">RSS</a><br> + Maintained with ♥ for the web. <br> + Proud supporter of <a href="https://usefathom.com/ref/DKHJVX">Fathom</a> & <a href="https://nextdns.io/?from=74d3p3h8">NextDNS</a>. <br> + The content for this site is <a href="https://creativecommons.org/licenses/by-sa/2.0/">CC-BY-SA</a>.<br> The <a href="https://git.sr.ht/~bt/bt.ht">code for this site</a> is <a href="https://git.sr.ht/~bt/bt.ht/tree/master/item/LICENSE">MIT</a>. + </small> +</footer>
