You can do something like this:

html, body {
  margin: 0;
  height: 100%; /* can also use viewport units (height: 100vh) */
}

#container {
  display: flex; /* displays flex-items (children) inline */
  flex-direction: column; /* stacks them vertically */
  height: 100%; /* needs to take the parents height, alternative: body {display: flex} */
}

main {
  flex: 1; /* takes the remaining height of the "container" div */
  overflow: auto; /* to scroll just the "main" div */
}

section {
  height: 100%; /* takes the visible area of the "main" div */
  overflow: auto; /* recommended */
  border-bottom: 1px solid;
  background: lightgreen;
}

header {background: #f88}
section:last-child {border: none}
footer {background: lightblue}
