+# Shiny, Animated CSS Buttons
+
+2021-04-27
+
+Everyone can appreciate fancy, animated buttons - but often times they come with a performance cost: *JavaScript*. Luckily for us, we can create our very own shiny, animated buttons with pure CSS.
+
+## The Demo
+

+
+[Live CodePen Example](https://codepen.io/bradleytaunt/pen/oNBQevj)
+
+## The HTML
+
+Nothing fancy going on here, just a set of `ahref` elements with specific `button` classes added:
+
+
+    <a href="#" class="button green"><span>Green Button</span></a>
+    <a href="#" class="button blue"><span>Blue Button</span></a>
+    <a href="#" class="button orange"><span>Orange Button</span></a>
+    <a href="#" class="button purple"><span>Purple Button</span></a>
+
+
+## The CSS
+
+First we set the default base styling for all the buttons. We also place the inner text into `span` elements (I will explain why in a little bit):
+
+
+    .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;
+    }
+
+
+Now we need to create our *shiny* element that will pass across the button on `hover` or `focus`. For this object we will use the `before` pseudo element:
+
+
+    .button:before {
+        background: linear-gradient(transparent 0%, rgba(255,255,255,0.6) 50%, transparent 100%);
+        content:'';
+        height: 200%;
+        position: absolute;
+        right: calc(100% + 20px);
+        top: -55%;
+        transform: rotate(-70deg);
+        transition: .6s ease-in-out right;
+        width: 80px;
+        z-index: 0;
+    }
+
+
+Next, we tell the `before` element to swipe across the main `.button` parent element when the user hovers or focuses on it. Remember placing our inner content into a `span` element? That insures that our shiny/swipe element doesn't position itself *over* the text, but instead flows under it:
+
+
+    .button:hover:before {
+        right: -100%;
+    }
+    /* Extra visual styling for buttons on hover - optional */
+    .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;
+    }
+
+
+All that's left is adding some visual flare to each individual button - in this case background-color and border-color:
+
+
+    .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; }
+
+
+## Browser Support
+
+These buttons work across all browsers flawlessly. See the details [on the caniuse report itself](https://caniuse.com/css-gencontent).
