The <code>z-index</code> property on the label is important for how we will be stacking our content on the z-axis (labels above inner content for example).</p> -<pre><code>/* Hide the default radio inputs */ -.tab-input { - position: absolute; - visibility: hidden; -} - -/* The main tab headings */ -.tab-label { - background: white; - box-shadow: inset 0 -4px 4px rgba(0,0,0,0.02); - color: lightgrey; - cursor: pointer; - display: inline-block; - font-weight: 600; - margin: 0 5px 0 0; - padding: 10px 20px; - position: relative; - text-align: center; - z-index: 0; -} -</code></pre> -<p>The main inner content of each tab needs to have an <code>absolute</code> position set as it’s default, since the one currently selected will switch to <code>relative</code> on mobile (more on that in a moment):</p> -<pre><code>/* The inner tab content */ -.tab-content { - background: white; - bottom: 0; - box-shadow: 0 6px 8px rgba(0,0,0,0.02); - left: 0; - overflow: scroll; - padding: 20px; - position: absolute; - right: 0; - top: 50px; - z-index: 0; -} -</code></pre> -<p>The final step is just telling the browser to style both the <code>label</code> and inner content of the currently selected radio <code>input</code>:</p> -<pre><code>/* Style the currently selected tab label */ -.tab-input:checked + .tab-label { - border: 1px solid #eee; - border-bottom: 0; - box-shadow: 0 -6px 8px rgba(0,0,0,0.02); - color: #268bd2; - z-index: 2; -} - -/* Show the currently selected tab content */ -.tab-input:checked ~ .tab-content { - border: 1px solid #eee; - z-index: 1; -} -</code></pre> -<p>It’s as simple as that! For reference, here is the entire CSS file for easier access:</p> -<pre><code>/* Main parent that holds all contents */ -.tabs { - height: 100%; - min-height: 250px; - position: relative; -} - -/* Each tab items (includes heading & content) */ -.tab-item { - display: inline; -} - -/* Hide the default radio inputs */ -.tab-input { - position: absolute; - visibility: hidden; -} - -/* The main tab headings */ -.tab-label { - background: white; - box-shadow: inset 0 -4px 4px rgba(0,0,0,0.02); - color: lightgrey; - cursor: pointer; - display: inline-block; - font-weight: 600; - margin: 0 5px 0 0; - padding: 10px 20px; - position: relative; - text-align: center; - z-index: 0; -} - -/* The inner tab content */ -.tab-content { - background: white; - bottom: 0; - box-shadow: 0 6px 8px rgba(0,0,0,0.02); - left: 0; - overflow: scroll; - padding: 20px; - position: absolute; - right: 0; - top: 50px; - z-index: 0; -} - -/* Style the currently selected tab label */ -.tab-input:checked + .tab-label { - border: 1px solid #eee; - border-bottom: 0; - box-shadow: 0 -6px 8px rgba(0,0,0,0.02); - color: #268bd2; - z-index: 2; -} - -/* Show the currently selected tab content */ -.tab-input:checked ~ .tab-content { - border: 1px solid #eee; - z-index: 1; -} -</code></pre> -<h2 id="dont-forget-about-mobile">Don’t forget about mobile</h2> -<p>With only a few extra lines of CSS we can ensure that our custom tabs will stack on top of each other and look solid on mobile devices:</p> -<pre><code>@media(max-width:38em) { - .tab-label { - display: block; - width: 100%; - } - .tab-content { - display: none; - } - .tab-input:checked ~ .tab-content { - bottom: auto; - display: block; - position: relative; - top: auto; - } -} -</code></pre> -<h2 id="one-minor-caveat">One minor caveat</h2> -<p>Even though I’m a pretty big fan of implementing tabs this way, there is a small drawback:</p> -<p>The <code>height</code> of the inner content doesn’t grow dynamically since it defaults as <code>absolute</code>, so a <code>min-height</code> or <code>height</code> value is required on the parent element. This could become a problem in certain situations where you don’t have the luxury of setting a static height.</p> -<p>Other than that, enjoy building some JavaScript-free tabs!</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>
