Using HTML Entities With CSS

I want to use the html entity version of < (& # 6 0 ; ) and > (& # 6 2 ; ) and make anything in-between them blue. If I just did it with p or something it would be fine but that's not possible. There's also the < span > deal but I don't want to span 32k things.

I just want it to be like this:
<blah blah blah blah blah stuff>

I have no idea why it renders the entities even with the code around them.
