+<p>2021-04-27</p>
+<p>Everyone can appreciate fancy, animated buttons - but often times they come with a performance cost: <em>JavaScript</em>. Luckily for us, we can create our very own shiny, animated buttons with pure CSS.</p>
+<h2 id="the-demo">The Demo</h2>
+<p><img src="/public/images/shiny-buttons.png" alt="Four buttons that shine when hovered" /></p>
+<p><a href="https://codepen.io/bradleytaunt/pen/oNBQevj">Live CodePen Example</a></p>
+<h2 id="the-html">The HTML</h2>
+<p>Nothing fancy going on here, just a set of <code>ahref</code> elements with specific <code>button</code> classes added:</p>
+<pre><code>&#60;a href="#" class="button green"&#62;&#60;span&#62;Green Button&#60;&#47;span&#62;&#60;&#47;a&#62;
+&#60;a href="#" class="button blue"&#62;&#60;span&#62;Blue Button&#60;&#47;span&#62;&#60;&#47;a&#62;
+&#60;a href="#" class="button orange"&#62;&#60;span&#62;Orange Button&#60;&#47;span&#62;&#60;&#47;a&#62;
+&#60;a href="#" class="button purple"&#62;&#60;span&#62;Purple Button&#60;&#47;span&#62;&#60;&#47;a&#62;
+</code></pre>
+<h2 id="the-css">The CSS</h2>
+<p>First we set the default base styling for all the buttons. We also place the inner text into <code>span</code> elements (I will explain why in a little bit):</p>
+<pre><code>.button {
+ background: white;
+ border: 1px solid #a5b1c2;
+ border-radius: 6px;
+ box-shadow: 0 4px 8px rgba(0,0,0,0.1);
+ color: #111111;
+ display: inline-block;
+ margin: 1rem auto;
+ min-width: 180px;
+ overflow: hidden;
+ padding: 15px 30px;
+ position: relative;
+ text-align: center;
+ text-decoration: none;
+ transition: .3s ease-in-out all;
+}
+.button span {
+ position: relative;
+ z-index: 2;
+}
+</code></pre>
+<p>Now we need to create our <em>shiny</em> element that will pass across the button on <code>hover</code> or <code>focus</code>. For this object we will use the <code>before</code> pseudo element:</p>
+<pre><code>.button:before {
+ background: linear-gradient(transparent 0%, rgba(255,255,255,0.6) 50%, transparent 100%);
+ content:&#39;&#39;;
+ height: 200%;
+ position: absolute;
+ right: calc(100% + 20px);
+ top: -55%;
+ transform: rotate(-70deg);
+ transition: .6s ease-in-out right;
+ width: 80px;
+ z-index: 0;
+}
+</code></pre>
+<p>Next, we tell the <code>before</code> element to swipe across the main <code>.button</code> parent element when the user hovers or focuses on it. Remember placing our inner content into a <code>span</code> element? That insures that our shiny&#47;swipe element doesn&#8217;t position itself <em>over</em> the text, but instead flows under it:</p>
+<pre><code>.button:hover:before {
+ right: -100%;
+}
+&#47;* Extra visual styling for buttons on hover - optional *&#47;
+.button:hover, button:focus {
+ box-shadow: 0 8px 12px rgba(0,0,0,0.1), inset 0 10px 30px rgba(255,255,255,0.3), inset 0 2px 2px rgba(255,255,255,0.2);
+ color: white;
+}
+</code></pre>
+<p>All that&#8217;s left is adding some visual flare to each individual button - in this case background-color and border-color:</p>
+<pre><code>.button.green:hover, button.green:focus { background: #20bf6b; border-color: #20bf6b; }
+.button.blue:hover, button.blue:focus { background: #0984e3; border-color: #0984e3; }
+.button.orange:hover, button.orange:focus { background: #ff793f; border-color: #ff793f; }
+.button.purple:hover, button.purple:focus { background: #6c5ce7; border-color: #6c5ce7; }
+</code></pre>
+<h2 id="browser-support">Browser Support</h2>
+<p>These buttons work across all browsers flawlessly. See the details <a href="https://caniuse.com/css-gencontent">on the caniuse report itself</a>.</p>
