CSS grid height wrong when using percent as grid gap

问题

I'm using a CSS grid with images in it and wanted to set a gap between elements that scales with the size of the grid. So I set the grid-gap to 2%, but doing that caused the grid height to be wrong, and caused the grid contents to overlap with the next element below. Using other units as the grid-gap, like vw works fine.

If I want to use a percentage as the gap, how can I fix the overlap problem?

Here's a minimal reproduction of the issue I'm running into:

.grid {
  display: grid;
  grid-template-columns: repeat(2, auto);
  grid-gap: 10%;
  background-color: #EEE
}

.grid-item {
  display: block;
  width: 100%;
}

<div class="grid">
  <img src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAADUlEQVR42mP839r6HwAHngMKGIKGywAAAABJRU5ErkJggg==" class="grid-item">

</div>

回答1:

the 10% seems to be honoured with flex.

.container {
   width:90%;
   margin:0 auto;
   display:block;
}

.grid {
  display: flex;
  justify-content:space-between;
  flex-wrap:wrap;
  width:100%;
  background-color: #EEE
}

.grid-item {
  flex:0 0 45%;
  max-width:500px;
  margin:0 0 10% 0;
  display: block;
}

img.grid-item:last-of-type {
   margin-bottom:0;
}

 <div class="container">
<div class="grid">
