如何在多个div周围放置边框

Question

I want to have a border around multiple divs, so I was trying to set the border around the parent div. However, this leads to a slight gap between the children and the parent (One of the children will have a different background color). Is there a way to prevent this behavior?

 .container { display: inline-flex; border: 1px solid black; } .child { padding: 0.5rem; } .child:first-child { background-color: red; }

 <div class="container"> <div class="child"> child1 </div> <div class="child"> child2 </div> </div>

Thanks!

Answer 1

The reason is still to be figured out. Maybe this happens because of the 0.5rem padding that for some reason doesn't coincide well with the fact that zoom of browser is different than 100%. That's why px unit is better(?) Should I use px or rem value units in my CSS? )

But here's a workaround (using borders for the child indeed, but only top and bottom).

 .container { display: inline-flex; border-left: 1px solid black; border-right: 1px solid black; } .child { padding: 0.5rem; border-top: 1px solid black; border-bottom: 1px solid black; } .child:first-child { background-color: red; }

 <div class="container"> <div class="child"> child1 </div> <div class="child"> child2 </div> </div>
