Flexbox fill available space vertically

So you can try this:

  1. flex-direction: column for the flex container.

  2. flex: 1 for the element that needs to fill the remaining space.

See demo below where the flexbox spans the viewport height:

body {
  margin: 0;
}
*{
  box-sizing: border-box;
}
.row {
  display: flex;
  flex-direction: column;
  height: 100vh;
}
.flex {
  flex: 1;
}
.row, .row > * {
  border: 1px solid;
}
<div class="row">
  <div>some content</div>
  <div class="flex">This fills the available space</div>
  <!-- fills/grows available space -->
  <div>another content</div>
</div>

Cheers!


You just need to use flex-direction: column on parent and flex: 1 on middle div.

body,
html {
  padding: 0;
  margin: 0;
}
.row {
  display: flex;
  flex-direction: column;
  min-height: 100vh;
}
.row > div:not(.flex) {
  background: #676EE0;
}
.flex {
  flex: 1;
  background: #67E079;
}
<div class="row">
  <div>some content</div>
  <div class="flex"></div>
  <!-- fills/grows available space -->
  <div>another content</div>
</div>
