I set out to see if I was able to create such an illusion with only 2 HTML elements and as little CSS as possible.</p> -<p>This is what I ended up creating:</p> -<p><img src="/public/images/css-orb.png" alt="Blue 3D orb made out pure CSS" /></p> -<p><a href="https://codepen.io/bradleytaunt/pen/VwvzKyb">Live CodePen Example</a></p> -<h2 id="the-html">The HTML</h2> -<p>Prepare for your mind to be blown:</p> -<pre><code><div class="main-orb"> - <div class="inner-orb"></div> -</div> -</code></pre> -<p>That’s it - I wasn’t kidding when I said we would use only 2 HTML elements. The <code>.main-orb</code> is the core shape (set to 400x400) and the <code>.inner-orb</code> is placed on top of it’s parent at a slightly smaller size (360x360) - but more on that below in the CSS portion.</p> -<h2 id="the-css">The CSS</h2> -<p>First we give the bigger orb element (<code>.main-orb</code>) the default styling needed to represent a 2D circle:</p> -<pre><code>.main-orb { - background: linear-gradient(#fff 0%, #eee 10%, #2E86FB 50%, #1A237E 100%); - border-radius: 9999px; - height: 400px; - margin: 4rem auto; - position: relative; /* This is important for the inner orb element later */ - width: 400px; -} -</code></pre> -<p>Next, we include both <code>:before</code> and <code>:after</code> pseudo elements for our orb’s drop shadow. You <em>could</em> do this with a simple <code>box-shadow</code> property on the <code>.main-orb</code> itself, but I’ve explained in a previous post why <a href="/blog/better-box-shadows.html">that’s not the best approach</a>.</p> -<pre><code>/* Shared styling for both pseudo elements - Remember DRY */ -.main-orb:before, .main-orb:after { - border-radius: 200px 200px 9999px 9999px; - bottom: -10px; - content:''; - filter: blur(20px); - height: 40px; - position: absolute; - z-index: -1; -} - -/* Bigger, lighter shadow */ -.main-orb:before { - background: rgba(0,0,0,0.4); - left: 7.5%; - width: 85%; -} - -/* Smaller, darker shadow */ -.main-orb:after { - background: rgba(0,0,0,0.7); - left: 20%; - width: 60%; -} -</code></pre> -<p>With our main orb complete we can move on to the <code>.inner-orb</code> element to help bring slightly more depth to our floating ball of CSS:</p> -<pre><code>.inner-orb { - background: linear-gradient(#fff 0%, #2E86FB 60%, #283593 100%); - border-radius: 9999px; - box-shadow: 0 8px 20px rgba(0,0,0,0.5); - height: 360px; - filter: blur(18px); - left: 20px; - position: absolute; - top: 15px; - width: 360px; -} -</code></pre> -<h2 id="poor-mans-3d-elements">Poor-man’s 3D elements</h2> -<p>Clearly implementing something like this will never come close to generating true 3D renders on a website, but it is a fun exercise to see how much further we can push simple CSS. Feel free to fork the above CodePen to play around with different colors and shadow placements.</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://barf.btxx.org">barf</a>. <br> - Feeds: <a href="/atom.xml">Atom</a> & <a href="/rss.xml">RSS</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>
