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

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

```
It can be done with the`::selection` CSS pseudo-element.
for example:

```
p::selection {
 background:red;
}

```
