Shiny, Animated CSS Buttons

Apr 27, 2021

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

See the Pen Shiny Buttons by Bradley Taunt (@bradleytaunt) on CodePen.

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.
