Question: How can I change the background color from selected text? Like selecting this question but instead of a blue background and white text, a white background and red, blue, white etc. text.  

Thanks, VVW

Answer: 
You can use `::selection` CSS to achieve this.
Eg:

```css
::selection {
  background:#fff;
  color:red;
}

```
In CSS3, you can use the `::selection` declaration.

```
::selection { background: #00FF00; }

```
