For this we want to display 3 simple payment choices to the user:</p> +<ul> +<li>One-time payment</li> +<li>Recurring payment</li> +<li>Free tier payment</li> +</ul> +<h2 id="the-final-demo">The Final Demo</h2> +<p><a href="https://codepen.io/bradleytaunt/embed/vYXjpLO">Live CodePen</a></p> +<p>Let’s get started with the base skeleton.</p> +<h2 id="the-html">The HTML</h2> +<pre><code><div class="radio-toggles"> + <input type="radio" id="option-1" name="radio-options"> + <label for="option-1">One-Time</label> + <input type="radio" id="option-2" name="radio-options" checked> + <label for="option-2">Recurring</label> + <input type="radio" id="option-3" name="radio-options"> + <label for="option-3">Free</label> + <div class="slide-item"></div> +</div> +</code></pre> +<h2 id="the-css">The CSS</h2> +<p>Now for the main event – the CSS. First we want to style the wrapper that holds all of our pieces together. You can tweak this to your liking, but I prefer a simple and clean style:</p> +<pre><code>.radio-toggles { + align-items: center; + background: #eee; + border: 1px solid lightgrey; + border-radius: 9999px; + display: flex; + justify-content: center; + margin: 20px auto; + max-width: 400px; + overflow: hidden; + padding: 4px; + position: relative; +} +</code></pre> +<p>Next, we “hide” (only visually) the default <code>radio</code> inputs:</p> +<pre><code>input[type="radio"] { + left: -9999px; + position: absolute; + z-index: -1; +} +</code></pre> +<p>Then we give the corresponding <code>label</code> elements a little spacing and breathing room:</p> +<pre><code>label { + cursor: pointer; + padding: 10px 20px; + text-align: center; + width: 33.33%; + z-index: 2; +} +</code></pre> +<p>Remember that <code>.slide-item</code> I referenced earlier? That element will be the visual “slider” that animates between the individual radio options. We style that like so:</p> +<pre><code>.slide-item { + background: white; + border-radius: 9999px; + box-shadow: 0 2px 4px rgba(0,0,0,0.15); + height: calc(100% - 8px); + left: calc(33.33% + 4px); + position: absolute; + width: calc(33.33% - 8px); + transition: left .4s; + z-index: 0; +} +</code></pre> +<p>You’ll notice the <code>left</code>, <code>height</code>, and <code>width</code> properties utilize the CSS <code>calc</code> attributes – this just gives some much needed padding and visual clean-up to the whole tabbed interface.</p> +<p>For the finishing touches, we just need to tell the <code>.slide-item</code> where to position itself based on which <code>radio</code> input is currently selected:</p> +<pre><code>input[type="radio"]:nth-of-type(1):checked ~ .slide-item { + left: 4px; +} +input[type="radio"]:nth-of-type(3):checked ~ .slide-item { + left: calc(66.66% + 4px); +} +</code></pre> +<p>That’s pretty much it! You now have a fully functional, animated toggle slider with just a set of simple <code>radio</code> inputs and pure CSS.</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>
