The need is to have the .card-media column width set to 0 when empty.
.card {
display: grid;
grid-template-columns: minmax(0, 24%) 1fr;
grid-template-rows: auto 1fr auto;
grid-auto-flow: row;
grid-template-areas: 'card-media card-title' 'card-media card-content' 'card-action card-action';
padding: 1rem;
width: 100%;
}
.card-media {
grid-area: card-media;
margin-right: 2%;
float: left
}<div class="card">
<div class="card-media"></div>
<div class="card-content">
<div class="card-title">Title</div>
<div class="card-text">
<p>Content</p>
</div>
<div class="card-action">
<button class="btn">Some action</button>
</div>
</div>
</div>In this case, although empty, the .card-media column remain at 24% width. Same result when using minmax(auto, 24%).
Can I set that column to 0 using CSS Grid?
This snippet simply sets display: none if the element is empty:
.card {
display: grid;
grid-template-columns: minmax(0, 24%) 1fr;
grid-template-rows: auto 1fr auto;
grid-auto-flow: row;
grid-template-areas: 'card-media card-title' 'card-media card-content' 'card-action card-action';
padding: 1rem;
width: 100%;
}
.card-media {
grid-area: card-media;
margin-right: 2%;
float: left;
}
.card-media:empty {
display: none;
}<div class="card">
<div class="card-media"></div>
<div class="card-content">
<div class="card-title">Title</div>
<div class="card-text">
<p>Content</p>
</div>
<div class="card-action">
<button class="btn">Some action</button>
</div>
</div>
</div>You are actually looking for fit-content()
use it like this:
grid-template-columns: fit-content(24%) 1fr;
And apply to .card-media
min-width: 0;
to make it have no minimum width.
