Question: I can't seem to change the background color of a div I have in my HTML, here is what I have so far:

```html
<div class="footer">
  <div class="left-footer">
  </div>
  <div class="center-footer">
  </div>
  <div class="right-footer">
  </div>
</div>

```

```css
.footer {
  color: #FF0000;
  width: 100%;
}

```

Answer: 
You're probably after something like this:

```
.footer {
    color: #FF0000;
    width: 100%;
    background-color: blue;
}

```

You'll also need some content in the actual div's to see the background colour, or set height/padding
You may need background-color, instead of color. Color is normally for font color
