Don&#t use CSS position: absolute to overlay two elements

Let's asume you have the following HTML structure to overlay an image with a header:

<div>



<p>You could be tempted to position the header absolute:<br>
</p>

<pre class="brush:php;toolbar:false">.card {
    position: relative;
    width: 300px;
}
.card > * {
    margin: 0;
}
.card header {
    position: absolute;
    width: 100%;
    height: 100%;
    background-color: #fff3;
}

...but then you loose layout on the header. Use grid instead:

.card {
    display: grid;
    width: 300px;
}
.card > * {
    grid-area: 1/1;
    margin: 0;
}
.card header {
    background-color: #fff3;
}

Here is a codepen link with the full example.

Happy coding!
