This button would then display the menu items upon interaction. Let me show you how to create such an element with only CSS - no need for JavaScript today!</p> +<h2>Before we begin</h2> +<p>I would like to point out that the concept of "toggling" the main menu (even for mobile) is not always the best solution. If you're interested, you can take a look at a previous article I wrote explaining why: <a href="/hamburger-menu-alternative.html">Using Hamburger Menus? Try Sausage Links</a></p> +<p>Now that we have mentioned possible pitfalls of relying so heavily on toggle menus, let's build one!</p> +<h2>Our Final Product</h2> +<p><img src="/public/images/menu-toggle-css.png" alt="Menu toggle made from pure CSS" /></p> +<p><a href="https://codepen.io/bradleytaunt/pen/mdEEvEX">Live CodePen Example</a></p> +<h2>The HTML</h2> +<p>To implement this design you really don't need much in terms of HTML:</p> +<ul> +<li>A single <code>checkbox</code> input</li> +<li>A <code>label</code> that corresponds to the <code>checkbox</code></li> +<li>A <code>nav</code> element to house our unordered list items</li> +</ul> +<pre><code><!-- The checkbox input & label partner --> +<input type="checkbox" id="menu-toggle"> +<label for="menu-toggle">Menu</label> + +<!-- The navigation we wish to toggle --> +<nav> + <ul> + <li><a href="">Home</a></li> + <li><a href="">About</a></li> + <li><a href="">Articles</a></li> + <li><a href="">Colophon</a></li> + <li><a href="">Contact</a></li> + </ul> +</nav> +</code></pre> +<p>That's it!</p> +<h2>The CSS</h2> +<p>The first thing we need to do is "hide" the <code>checkbox</code> input element. It's important to avoid using <code>display: none</code> or <code>visibility: hidden</code> in order to achieve this. Those CSS properties can negatively impact accessibility (specifically screen readers). So we will be relying on the <code>position</code>, <code>z-index</code> and <code>opacity</code> properties to help us out.</p> +<pre><code>/* Set the input position to absolute, send it off screen with zero opacity */ +input[type="checkbox"] { + left: -9999px; + opacity: 0; + position: absolute; +} +</code></pre> +<p>Then we give our corresponding <code>label</code> a minor face-lift to make it appear more button-like:</p> +<pre><code>/* Minor visual styling to make the label more button-y */ +label { + border: 1px solid currentColor; + border-radius: 4px; + cursor: pointer; + padding: 10px; +} +</code></pre> +<p>For our main <code>nav</code> element, we want to set it's position to <code>absolute</code> in order to avoid any janky page rendering issues that might occur when toggling the menu:</p> +<p>` +</p> +<pre><code>/* Set nav to absolute (avoids odd page rendering space pop-in) */ +nav { + opacity: 0; + position: absolute; + z-index: -2; +} +</code></pre> +<p>The last step is to actually <em>show</em> the menu if the user toggles the <code>checkbox</code>:</p> +<pre><code>/* Show nav when checkbox is checked */ +input[type="checkbox"]:checked ~ nav { + opacity: 1; + z-index: 1; +} +</code></pre> +<p>It might not look like much, but you now have a fully functional menu toggle - <strong>made with pure CSS</strong>! </p> +<h2>With Great Power...</h2> +<p>Although this design is very simple to implement, please remember to use these types of menus wisely. Just because you <em>can</em> do something, doesn't always mean you <em>should</em>.</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://git.sr.ht/~bt/barf">barf</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>
