Answer 1

This layout is perfect to use flex.

csshtml,
body {
  height: 100%;
}

body {
  margin: 0;
}

article {
  height: 100%;
  display: flex;
  flex-direction: column;
  text-align: center;
}

header {
  height: 50px;
  background: #ccc;
}

footer {
  height: 50px;
  background: #ccc;
}

section {
  flex: 1;
  background: #eee;
}
