A full-height page with a fixed sidebar and scrollable content area can be created by setting the height to 100% and applying proper positioning of elements.
The following example illustrates the above.
Example
<!DOCTYPE html>
<html>
<head>
<style>
.main {
margin-left: 140px;
font-size: 200%;
padding: 0 3%;
}
section {
height: 400px;
background-color: tomato;
}
.sidebar {
height: 100%;
width: 140px;
top: 0;
left: 0;
position: fixed;
background-color: darkslategrey;
padding-top: 20px;
}
.sidebar a {
display: block;
padding: 2% 4%;
text-decoration: none;

font-size: 1.4em;
}
.sidebar a:hover {

font-size: 1.8em;
box-shadow: inset 0 0 15px rgba(0,0,0,0.6)
}
</style>
</head>
