After I looked around some themes, I realized that the Twilight Theme separating parts of the code with different background colors.
It looks like selected, but it isn’t. It seems that it colorizing the background of different parts in the code. (example <?php ?p> part in a PHP file)
How this is called?
And are there plugins out there who working more advanced with these behavior?
I often thought how nice it could be if while, for, if statements could have different backgrounds. Or that the developer can set start and end points for different background colors in the code with comments parameters.
Is there something like this out there?
More advanced?
