<p>Default radio inputs are notoriously horrible looking and are something designers tend to over-think when trying to customize them. Let&#8217;s walk through how to create custom radio buttons with <em>pure CSS</em>, while still preserving performance and accessibility.</p>

-
<pre><code>&#60;input class="radio-btn" name="radio-collection" id="radio-1" type="radio"&#62;
</code></pre>

<p>This is the default <code>radio</code> input. We give it:</p>
-
<ul>
<li>a <code>name</code> (inputs with a shared <code>name</code> are grouped together)</li>
<li>an <code>id</code> (so our label can target this input)</li>
<li>a <code>class</code> (so we can style it later)</li>
</ul>
-
<p><strong>Important</strong>: be sure to have a unique <code>id</code> for each input so your labels don&#8217;t end up connected to multiple radios. In this demo we are simply incrementing them by one.</p>
-
<h3 id="labels">Labels</h3>
-
<p>Adding the labels is fairly straightforward, we just include the corresponding input&#8217;s <code>id</code> in the label&#8217;s <code>for</code> attribute. The label content is wrapped in a <code>span</code> - which I will explain the reasoning for later.</p>
-
<p>For styling purposes we also add the <code>radio-label</code> class.</p>
-
<pre><code>&#60;label class="radio-label" for="radio-1"&#62;&#60;span&#62;I am very satisfied&#60;&#47;span&#62;&#60;&#47;label&#62;

<p>First we give some basic styling to our <code>label</code> and <code>input</code> classes (along with hover states). The <code>radio</code> element is actually hidden from view, but by using the <code>visibility</code> attribute we still keep it accessible for screen-readers.</p>

<p>I hope this shows new designers that simple custom radio inputs aren&#8217;t so hard to implement after-all and can actually be pretty fun to design.</p>
