+<p>2019-02-18</p>
+<p>Sometimes there is a need to use toggle elements in-place of the default <code>checkbox</code> inputs. 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 id="what-we-will-be-building">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 id="the-html">The HTML</h2>
+<p>The build structure for these toggles is really simple, we only need:</p>
+<ul>
+<li><p>a parent container to hold all our corresponding elements</p></li>
+<li><p>a checkbox <code>input</code> element (which we will hide)</p></li>
+<li><p>an empty label designed to represent the slider</p></li>
+<li><p>a text label that references the <code>input</code> </p>
+<p>&#47;* Main toggle parent container <em>&#47;
+
+ &#47;</em> Checkbox input, hidden with CSS <em>&#47;
+
+ &#47;</em> The toggle slider element <em>&#47;
+
+ &#47;</em> The text label to the right of the slider *&#47;
+ Toggle Switch
+</p></li>
+</ul>
+<p>And that&#8217;s everything we need for the HTML.</p>
+<p><strong>ProTip:</strong> Don&#8217;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&#8217;s overlooked more than you think.</p>
+<h2 id="the-css">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: CSS variables.</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&#8217;t be needing it:</p>
+<pre><code>.toggle-input {
+ position: absolute;
+ visibility: hidden;
+ z-index: -1;
+}
+</code></pre>
+<p>Let&#8217;s also add some base styling for the <code>label</code> containing the text corresponding to it&#8217;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>&#47;* This is just the main slider base *&#47;
+.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:&#39;&#39;;
+ height: 16px;
+ left: 2px;
+ position: absolute;
+ top: 2px;
+ transition: all ease .3s;
+ width: 16px;
+}
+</code></pre>
+<h3 id="interaction">Interaction</h3>
+<p>Right now we just have a static toggle that does nothing when the user interacts with it. Let&#8217;s change that by moving the pseudo element&#8217;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 {
+ &#47;* Move 100% of the width minus it&#39;s own width plus initial &#39;left&#39; *&#47;
+ 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 id="final-code">Final code</h2>
+<p>To make things easier, you can find the HTML &#38; CSS is their entirety below:</p>
