<h1 id="animated-card-tiles">Animated Card Tiles</h1>
<p>2019-02-27</p>
<p><em>The design trend of using “cards” or “tiles” to display interactive</em> sections/article headings in an app or website remains a popular choice among designers. So, let’s build a set of animated cards with only HTML & CSS. </p>
<h2 id="what-we-will-be-building-live-demo">What we will be building (live demo)</h2>
<p>This is the set of animated card tiles we will be creating:</p>
<p><em>(try hovering)</em></p>
<p><a href="https://codepen.io/bradleytaunt/pen/rNjBpob">Live CodePen</a></p>
<h2 id="the-html">The HTML</h2>
<p>For the base skeleton of these cards we only need:</p>
<ul>
<li><p>a <code>flexbox</code> main container to hold everything</p></li>
<li><p>a <code>.card-tile</code> parent element</p></li>
<li><p>the inner child element that will display on <code>:hover</code></p></li>
<li><p>proper <code>h4</code> and <code>p</code> tags inside that child element</p></li>
</ul>
<p>That’s all that is needed - for now. We will be returning to this code shortly to add some extra classes to make our lives easier.</p>
<h2 id="the-css">The CSS</h2>
<p>First we set the main housing container to use <code>flex</code> so we save ourselves the headache of aligning all the cards in a nice row:</p>
<pre><code>.card-tiles-container {
display: flex;
font-size: 14px;
margin: 20px 0;
}
</code></pre>
<p>Next we create the default styling for our tile cards and set the <code>transform</code> property to scale the card on <code>:hover</code>:</p>
<pre><code>/* Default card tile styles */
.card-tile {
border: 1px solid;
border-radius: 10px;
cursor: pointer;
height: 150px;
margin: 0 10px;
overflow: hidden;
position: relative;
width: 33.33%;
}
.card-tile:hover {
transform: scale(1.1);
}
</code></pre>
<h3 id="where-are-my-cards">Where are my cards?!</h3>
<p>Don’t panic if you can’t <em>visually</em> see any card elements in your demo yet - that’s to be expected. We will be styling these card elements momentarily.</p>
<p>Our next step is to hide the default inner <code>text-content</code> and only show it on hover. We achieve this by setting it’s position to <code>absolute</code>, placing it’s opacity at 0 and pushing it’s z-index back to -1.</p>
<p>When the user hovers over a main card tile, we change the <code>text-content</code> values of both the opacity and z-index to 1.</p>
<pre><code>/* Card tile text content */
.card-tile .text-content {
background: linear-gradient(rgba(0,0,0,0.4) 0%, rgba(0,0,0,0.6) 100%);
bottom: 10px;
border: 1px solid rgba(0,0,0,0.4);
border-radius: 5px;
box-shadow: inset 0 1px 1px rgba(255,255,255,0.8),
0 2px 4px rgba(0,0,0,0.5);
height: 65px;
left: 10px;
opacity: 0;
padding: 10px;
position: absolute;
width: calc(100% - 20px);
z-index: -1;
}
.card-tile:hover .text-content {
opacity: 1;
z-index: 1;
}
</code></pre>
<p>Finally we add some minor styling for the inner header and paragraph tags:</p>
<pre><code>.card-tile .text-content h4,
.card-tile .text-content p {
color: #fff;
margin: 0;
text-shadow: 1px 1px 1px rgba(0,0,0,0.6);
}
</code></pre>
<h3 id="dont-forget-mobile">Don’t forget mobile</h3>
<p>We want out UI to stack the cards if users are viewing them on smaller devices:</p>
<pre><code>@media(max-width: 600px) {
.card-tiles-container {
flex-direction: column;
}
.card-tile {
margin: 0 0 10px 0;
width: 100%;
}
}
</code></pre>
<h2 id="customizing-each-card">Customizing each card</h2>
<p>Remember how I mentioned that we would be adding more classes to the original HTML? Now is the time. We will be including a simple class on each card tile to provide it’s own custom coloring:</p>
<pre><code><div class="card-tiles-container">
<!-- `Blue` class -->
<div class="card-tile blue">
<div class="text-content">
<h4>Card Title</h4>
<p>Inner card content text</p>
</div>
</div>
<!-- `Orange` class -->
<div class="card-tile orange">
<div class="text-content">
<h4>Card Title</h4>
<p>Inner card content text</p>
</div>
</div>
<!-- `Green` class -->
<div class="card-tile green">
<div class="text-content">
<h4>Card Title</h4>
<p>Inner card content text</p>
</div>
</div>
</div>
</code></pre>
<p>And these color classes correlate to some new CSS styling:</p>
<pre><code>/* Blue Card */
.card-tile.blue {
background-color: #0093E9;
background-image: linear-gradient(0deg, #0093E9 0%, #80D0C7 100%);
border-color: #0093E9;
box-shadow: 0 4px 12px rgba(128,208,199,0.7),
inset 0 2px 1px rgba(255,255,255,0.6);
}
.card-tile.blue:hover {
box-shadow: 0 8px 18px rgba(128,208,199,0.4),
inset 0 2px 1px rgba(255,255,255,0.6);
}
/* Orange Card */
.card-tile.orange {
background-color: #FAD961;
background-image: linear-gradient(180deg, #FAD961 0%, #F76B1C 100%);
border-color: #F76B1C;
box-shadow: 0 4px 12px rgba(247,107,28,0.7),
inset 0 2px 1px rgba(255,255,255,0.6);
}
.card-tile.orange:hover {
box-shadow: 0 8px 18px rgba(247,107,28,0.4),
inset 0 2px 1px rgba(255,255,255,0.6);
}
/* Green Card */
.card-tile.green {
background-color: #096e40;
background-image: linear-gradient(0deg, #096e40 0%, #2AF598 100%);
border-color: #096e40;
box-shadow: 0 4px 12px rgba(9,110,64,0.7),
inset 0 2px 1px rgba(255,255,255,0.6);
}
.card-tile.green:hover {
box-shadow: 0 8px 18px rgba(9,110,64,0.4),
inset 0 2px 1px rgba(255,255,255,0.6);
}
</code></pre>
<h3 id="adding-transitions">Adding transitions</h3>
<p>We can now see the actual cards visually and have the ability to interact with them, but there is a problem - they don’t animate.</p>
<p>Lucky we can target all elements we wish to animate with the <code>transition</code> property, like so:</p>
<pre><code>/* Shared transitions */
.card-tile,
.card-tile .text-content {
transition: .3s ease all;
}
</code></pre>
<p>Done and done.</p>
<h2 id="the-final-code">The final code</h2>
<p>To make things easier for reference, I have included all the <code>html</code> and <code>css</code> below. Please feel free to use these cards anywhere you like and change them as you see fit!</p>
