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 id="before-we-begin">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 id="our-final-product">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 id="the-html">The HTML</h2> +<p>To implement this design you really don’t need much in terms of HTML:</p> +<ul> +<li><p>A single <code>checkbox</code> input</p></li> +<li><p>A <code>label</code> that corresponds to the <code>checkbox</code></p></li> +<li><p>A <code>nav</code> element to house our unordered list items</p> +<p>Menu</p></li> +</ul> +<p>That’s it!</p> +<h2 id="the-css">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>` + /* Set nav to absolute (avoids odd page rendering space pop-in) */ + nav { + opacity: 0; + position: absolute; + z-index: -2; + }</p> +<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 id="with-great-power">With Great Power…</h2> +<p>Although this design is very simple to implement, please remember to use these types of menus wisely.
