The problem is, I tend to see a lot of developers reaching for plugins or JavaScript components in order to implement these toggles.</p> +<p><em>This is overkill</em>. You can create your own custom <code>input</code> elements to mimic toggles perfectly with just a small amount of CSS.</p> +<h2>What we will be building</h2> +<p><img src="/public/images/easy-toggle-switches.png" alt="Easy toggle switches" /></p> +<p><a href="https://codepen.io/bradleytaunt/pen/bGgbajY">Live CodePen Example</a></p> +<h2>The HTML</h2> +<p>The build structure for these toggles is really simple, we only need:</p> +<ul> +<li>a parent container to hold all our corresponding elements</li> +<li>a checkbox <code>input</code> element (which we will hide)</li> +<li>an empty label designed to represent the slider</li> +<li>a text label that references the <code>input</code> </li> +</ul> +<pre><code>/* Main toggle parent container */ +<div class="toggle-switch"> + /* Checkbox input, hidden with CSS */ + <input class="toggle-input" type="checkbox" id="toggle-1"> + /* The toggle slider element */ + <label class="toggle-slider" for="toggle-1"></label> + /* The text label to the right of the slider */ + <label class="toggle-label" for="toggle-1">Toggle Switch</label> +</div> +</code></pre> +<p>And that's everything we need for the HTML.</p> +<p><strong>ProTip:</strong> Don't forget to increment both the <code>id</code> and <code>for</code> attributes when adding additional toggles. This seems like a no-brainer but it's overlooked more than you think.</p> +<h2>The CSS</h2> +<p>To get things started we will add the styling to the <code>.toggle-switch</code> item directly (using <code>flexbox</code> in this demo for easier layout).</p> +<p><strong>Sidenote</strong>: You will notice the inclusion of CSS variables in this demo - if you are unfamiliar with how to use root variables in CSS, take a look at one of my previous posts: <a href="https://accssible.com/2018/03/24/css-variables/">CSS variables</a>.</p> +<pre><code>:root { + --primary-color: #4A90E2; +} + +.toggle-switch { + align-items: center; + display: flex; + font-size: 14px; + justify-content: center; + margin: 20px 0; +} +</code></pre> +<p>Next we will hide the default browser checkbox element since we won't be needing it:</p> +<pre><code>.toggle-input { + position: absolute; + visibility: hidden; + z-index: -1; +} +</code></pre> +<p>Let's also add some base styling for the <code>label</code> containing the text corresponding to it's <code>input</code> sibling:</p> +<pre><code>.toggle-label { + color: #ccc; + cursor: pointer; + font-weight: bold; + padding-left: 10px; + text-shadow: 1px 1px 0 rgba(255,255,255,0.3); + transition: ease all .3s; +} +</code></pre> +<p>Now we target the <code>.toggle-slider</code> label and add the styling for the main slider base:</p> +<pre><code>/* This is just the main slider base */ +.toggle-slider { + background: #eee; + border-radius: 9999px; + box-shadow: inset 0 2px 4px rgba(0,0,0,0.1), + inset 0 4px 8px rgba(0,0,0,0.1), + 0 1px 1px rgba(255,255,255,1); + cursor: pointer; + display: inline-block; + height: 20px; + position: relative; + transition: all ease .3s; + width: 40px; +} +</code></pre> +<p>We <em>could</em> include a separate element for the circle toggle switcher itself, but instead we will use the <code>:before</code> pseudo element:</p> +<pre><code>.toggle-slider:before { + background: white; + border-radius: 9999px; + box-shadow: 0 4px 8px rgba(0,0,0,0.1), + 0 2px 4px rgba(0,0,0,0.2); + content:''; + height: 16px; + left: 2px; + position: absolute; + top: 2px; + transition: all ease .3s; + width: 16px; +} +</code></pre> +<h3>Interaction</h3> +<p>Right now we just have a static toggle that does nothing when the user interacts with it. Let's change that by moving the pseudo element's position based on the checkbox <code>input</code> state and updating the label text color:</p> +<pre><code>.toggle-input:checked + .toggle-slider { + background: var(--primary-color); +} +.toggle-input:checked + .toggle-slider:before { + /* Move 100% of the width minus it's own width plus initial 'left' */ + left: calc(100% - 18px); +} + +.toggle-input:checked ~ .toggle-label { + color: var(--primary-color); +} +</code></pre> +<p>And because we already included the <code>transition</code> property on both the base slider and label text, everything animates nicely between state changes.</p> +<h2>Final code</h2> +<p>To make things easier, you can find the HTML & CSS is their entirety below:</p> +<h3>HTML</h3> +<pre><code><div class="toggle-switch"> + <input class="toggle-input" type="checkbox" id="toggle-1"> + <label class="toggle-slider" for="toggle-1"></label> + <label class="toggle-label" for="toggle-1">Toggle Switch</label> +</div> +<div class="toggle-switch"> + <input class="toggle-input" type="checkbox" id="toggle-2"> + <label class="toggle-slider" for="toggle-2"></label> + <label class="toggle-label" for="toggle-2">Toggle Switch</label> +</div> +<div class="toggle-switch"> + <input class="toggle-input" type="checkbox" id="toggle-3" checked> + <label class="toggle-slider" for="toggle-3"></label> + <label class="toggle-label" for="toggle-3">Toggle Switch</label> +</div> +<div class="toggle-switch"> + <input class="toggle-input" type="checkbox" id="toggle-4"> + <label class="toggle-slider" for="toggle-4"></label> + <label class="toggle-label" for="toggle-4">Toggle Switch</label> +</div> +</code></pre> +<h3>The CSS</h3> +<pre><code>:root { + --primary-color: #4A90E2; +} +.toggle-switch { + align-items: center; + display: flex; + font-size: 14px; + justify-content: center; + margin: 20px 0; +} +.toggle-input { + position: absolute; + visibility: hidden; + z-index: -1; +} +.toggle-slider { + background: #eee; + border-radius: 9999px; + box-shadow: inset 0 2px 4px rgba(0,0,0,0.1), + inset 0 4px 8px rgba(0,0,0,0.1), + 0 1px 1px rgba(255,255,255,1); + cursor: pointer; + display: inline-block; + height: 20px; + position: relative; + transition: all ease .3s; + width: 40px; +} +.toggle-slider:before { + background: white; + border-radius: 9999px; + box-shadow: 0 4px 8px rgba(0,0,0,0.1), + 0 2px 4px rgba(0,0,0,0.2); + content:''; + height: 16px; + left: 2px; + position: absolute; + top: 2px; + transition: all ease .3s; + width: 16px; +} +.toggle-input:checked + .toggle-slider { + background: var(--primary-color); +} +.toggle-input:checked + .toggle-slider:before { + left: calc(100% - 18px); +} +.toggle-label { + color: #ccc; + cursor: pointer; + font-weight: bold; + padding-left: 10px; + text-shadow: 1px 1px 0 rgba(255,255,255,0.3); + transition: ease all .3s; +} +.toggle-input:checked ~ .toggle-label { + color: var(--primary-color); +} +</code></pre> +<p>Enjoy your custom toggles!</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>
