How to change the background color of a line of user input in a textarea?
I know how to change the background color of a textarea, but what about changing the background color of the text that users type into a text area?
For example, in HTML you can change the background color of a span of text using span tags, ie:
<span style="background-color: blue">Words with blue background</span>
...But what about the text that users type into a text field?
I need to do this for a form that I'm creating, so that users can clearly see spaces and returns they're entering as well as the characters they enter.
Can it be done using CSS?
