Remove white space below footer

Question

There's always a large empty white space below my footer. How do I ensure that the page ends at the end of the footer?

Answer 1

There are three solutions to this problem

In all of the following examples I've just a extremely basic HTML-template by only using three divs: header, content and footer. All the options are minified but should work fine on more advanced websites.

1. Using the background-color

Set for both the body and footer the same background-color.

body {
  margin: 0px;
  font-family: Arial;
  line-height: 20px;
  background-color: red;
}
#header {
  height: 20px;
  background: #222;
  color: white;
}
#content {
  background: gray;
  height: 200px;
}
#footer {
  height: 20px;
  background: red; /*Same as body, you could also use transparent */
  color: white;
}

<div id="header">
  Header
</div>
<div id="content">
  Content
</div>
<div id="footer">
  Footer
</div>

2. Using a sticky footer

Use a sticky footer that is fixed at the bottom of the browser window. (I wouldn't recommend this option, because many users don't like sticky footers. You could however use a sticky header)

body {
  margin: 0px;
  font-family: Arial;
  line-height: 20px;
}
#header {
  height: 20px;
  background: #222;
  color: white;
}
#content {
  height: 2000px;
}
#footer {
  position: fixed;
  width: 100%;
  bottom: 0;
  left: 0;
  height: 20px;
  background: #222;
  color: white;
}

<div id="header">
  Header
</div>
<div id="content">
  Content
</div>
<div id="footer">
  Footer
</div>

3. Using a minimum-height for the content

Set a minimum-height for the content div that equals the browser windows height minus the height of the header and footer. (This is my personal favorite because it works cross-browser and is responsive on all screens)

body {
  margin: 0px;
  font-family: Arial;
  line-height: 20px;
}
#header {
  height: 20px;
  background: #222;
  color: white;
}
#content {
  min-height: calc(100vh - 40px);
}
#footer {
  height: 20px;
  background: #222;
  color: white;
}

<div id="header">
  Header
</div>
<div id="content">
  Content
</div>
<div id="footer">
  Footer
</div>
