What exactly is CDATA and what does it do?

Question

I sometimes notice a CSS or JS code surrounded with and ]]> tags. I couldn\'t find any explanation to this. What does CDATA do? Why

Answer 1

It marks data that shouldn't be parsed - in most cases, just HTML or text that needs to be written directly to the page.
