this is a standard grid concept:
.wrap{
display:grid;
grid-template-columns: 1fr 1fr 1fr;
}
<div class='wrap'>
<div class='el'>lorem</div>
<div class='el'>ipsum</div>
<div class='el'>dolor</div>
</div>
I tried this:
<div class='wrap'>
<img class='el' src='...' alt='img'>
<img class='el' src='...' alt='img'>
<img class='el' src='...' alt='img'>
</div>
And seems it works - images as grid elements
So my question is - what else can I use as grid elements - inputs, forms, video...
I suppose there are some restrictions but can't find any specification regarding this.
Never rendered svg elements cannot be used as grid items for sure.
Other descendants of <svg>
elements also probably can't be used, though I can't find any spec on those.
For HTML elements, pretty much anything works as a grid item if you force it to generate a CSS box.
