I am trying to achieve this layout: Page is 1200px wide and centered Page fills 100% of the browser's height Page does not scroll The green and red divs should have inline scroll

Solution 1:

Using flexbox model make your design more easy. Look here:

html, body {
  height: 100%;
  width: 100%;
}

html {
  background-color: rgb(160,160,100);
}

body {
  padding: 0;
  margin: 0;
}

main {
  display: flex;
  flex-direction: column;
  flex-wrap: nowrap;
  justify-content: flex-start;
  align-content: stretch;
  align-items: stretch;
  max-width: 1200px;
  margin: 0 auto;
  height: 100%;
}

header {
  min-height: 40px;
  flex: 0040px;
  background-color: rgba(100, 100, 0, 0.4);
  overflow: hidden;
}

nav {
  min-height: 80px;
  flex: 0080px;
  display: flex;
  flex-direction: row;
  flex-wrap: nowrap;
  justify-content: flex-start;
  align-content: stretch;
  align-items: stretch;
}

.logo {
  min-width: 80px;
  flex: 00 auto;
  background-color: yellow;
  overflow: hidden;
}

.nav-wrapper {
  flex: 11 auto;
  display: flex;
  flex-direction: column;
  flex-wrap: nowrap;
  justify-content: flex-start;
  align-content: stretch;
  align-items: stretch;
}

.nav-wrapper > div {
  flex: 11 auto;
  overflow: hidden;
}

.nav-wrapper > div:first-child {
  background-color: blue;
}

.nav-wrapper > div:last-child {
  background-color: grey;
}

.main {
  flex: 11 auto;
  display: flex;
  flex-direction: row;
  flex-wrap: nowrap;
  justify-content: flex-start;
  align-content: stretch;
  align-items: stretch;
  overflow: auto;
}

.main > div {
  flex: 1150%;
  line-height: 3em;
  align-self: auto;
  overflow: auto;
}

.main > div:first-child {
  background-color: rgba(255, 0, 0, 0.4);
}

.main > div:last-child {
  background-color: rgba(0, 100, 0, 0.4);
}

<main><header></header><nav><divclass="nav-wrapper"><div></div><div></div></div><divclass="logo"></div></nav><divclass="main"><div>
