Grid Property Similar to Flex-Grow

Question

I discovered a bug with Chrome version 75's implementation of flexbox. Hence I wanted to see if the issue persists with grid, but the test will only work if there is a grid property that is similar to flex-grow due to the current structure of my document.

body {
  display: flex;
  flex-direction: column;
}
header {
  /* height is implicitly determined by font-size and padding */
}
main {
  flex: 1;
  scrollbar-width: none;
  overflow-y: auto;
}
::-webkit-scrollbar {
  display: none;
  -ms-overflow-style: none;
}
footer {
  /* height is implicitly determined by font-size and padding */
}

Is there a similar grid property?

Answer 1

You can rely on 1fr to fill the remaining space:

body {
  display: grid;
  grid-template-rows: auto 1fr auto;
  margin: 0;
  height: 100vh;
}

header {
  padding: 15px;
  font-size: 1rem;
  background: red;
}

main {
  background: green;
  overflow:auto;
  padding:10px;
}

footer {
  padding: 15px;
  font-size: 1rem;
  background: blue;
}
