Aplying CSS to external .txt

Man…i really feel stupid, but i have this really simple doubt…
i’m creating a website, but i’m having problems loading an external .txt and aplying CSS.
i want to easely update my texts, instead of having to format it in HTML everytime, like the kirupa forums tells us to do. i think this is really simple, cause i just want it to detect a title and a text…can i create an external txt who tells the CSS file what i want?
something like:

title=help me please!
text=bla bla bla …

…and the CSS automatically detects whats supose to do ?

thanks in advance for any tip guys!
(and sorry for my terrible english!)
