How to create a sticky footer in CSS inside an absolutely positioned div?

Question

I would like to create a sticky footer inside an absolutely positioned div element.

My approach was to position the footer div absolutely as well - inside an ad

Answer 1

The only method I can think of here is flexbox and not absolute positioning.

  .page {
    position: relative;
    min-height: 100%;
    display: flex;
    flex-direction: column;
  }

  .footer {
    margin-top: auto;
    height: 30px;
    color: brown;
    border: 1px solid brown;
    background: rgba(255,255,255,0.5);
  }

body {
  color: white;
}

nav {
  position: absolute;
  top: 0;
  left: 0;
  bottom: 0;
  width: 200px;
  overflow: hidden;
}
nav .logo {
  position: absolute;
  top: 0;
  left: 0;
  right: 0;
  height: 60px;
  background-color: salmon;
}
nav .navmenu {
  margin: 0;
  position: absolute;
  top: 60px;
  left: 0;
  right: 0;
  bottom: 0;
  overflow-y: auto;
  padding: 10px 20px;
  background-color: pink;
}

.content-wrapper {
  position: absolute;
  top: 0;
  left: 200px;
  bottom: 0;
  right: 0;
  overflow: hidden;
}
.content-wrapper .header {
  position: absolute;
  top: 0;
  left: 0;
  right: 0;
  height: 60px;
  background-color: pink;
}
.content-wrapper .content {
  position: absolute;
  top: 60px;
  left: 0;
  right: 0;
  bottom: 0;
  overflow-y: auto;
  padding: 10px 20px;
  background-color: rosybrown;
}
.content-wrapper .page {
  position: relative;
  min-height: 100%;
  display: -webkit-box;
  display: -webkit-flex;
  display: -ms-flexbox;
  display: flex;
  -webkit-box-orient: vertical;
  -webkit-box-direction: normal;
  -webkit-flex-direction: column;
      -ms-flex-direction: column;
          flex-direction: column;
}
.content-wrapper .footer {
  margin-top: auto;
  height: 30px;
  color: brown;
  border: 1px solid brown;
  background: rgba(255, 255, 255, 0.5);
}

Some footer - it shouldn't overlap with the content if you resize the page
