Perfectly aligned buttons inside cards with flexbox

suggest change

It’s a regular pattern in design these days to vertically align call to actions inside its containing cards like this:

This can be achieved using a special trick with flexbox

HTML

<div class="cards">
  <div class="card">
    <p>Lorem ipsum Magna proident ex anim dolor ullamco pariatur reprehenderit culpa esse enim mollit labore dolore voluptate ullamco et ut sed qui minim.</p>
    <p><button>Action</button></p>
  </div>
  <div class="card">
    <p>Lorem ipsum Magna proident ex anim dolor ullamco pariatur reprehenderit culpa esse enim mollit labore dolore voluptate ullamco et ut sed qui minim.</p>
    <p>Lorem ipsum Magna proident ex anim dolor ullamco pariatur reprehenderit culpa esse enim mollit labore dolore voluptate ullamco et ut sed qui minim.</p>
    <p>Lorem ipsum Magna proident ex anim dolor ullamco pariatur reprehenderit culpa esse enim mollit labore dolore voluptate ullamco et ut sed qui minim.</p>
    <p>Lorem ipsum Magna proident ex anim dolor ullamco pariatur reprehenderit culpa esse enim mollit labore dolore voluptate ullamco et ut sed qui minim.</p>
    <p><button>Action</button></p>
  </div>
</div>

First of all, we use CSS to apply display: flex; to the container. This will create 2 columns equal in height with the content flowing naturally inside it

CSS

.cards {
    display: flex;
}
.card {
    border: 1px solid #ccc;
    margin: 10px 10px;
    padding: 0 20px;
}
button {
    height: 40px;
    background: #fff;
    padding: 0 40px;
    border: 1px solid #000;
}
p:last-child {
    text-align: center;
}

The layout will change and become like this:

In order to move the buttons to the bottom of the block, we need to apply display: flex; to the card itself with the direction set to column. After that, we should select the last element inside the card and set the margin-top to auto. This will push the last paragraph to the bottom of the card and achieve the required result.

Final CSS:

.cards {
    display: flex;
}
.card {
    border: 1px solid #ccc;
    margin: 10px 10px;
    padding: 0 20px;
    display: flex;
    flex-direction: column;
}
button {
    height: 40px;
    background: #fff;
    padding: 0 40px;
    border: 1px solid #000;
}
p:last-child {
    text-align: center;
    margin-top: auto;
}
