Using a PHP page to post "blog" entries on my website.

I’ve finally managed to setup a page that allows me to submit a message and retrieve it from another page on my website. Now, to go a step further, I’ve setup a news area on my homepage that display recent entries that I’ve made (very similar to a blog.) What I’m trying to do is submit a message on the page I’ve created, fetch it for use on my homepage, and place it right in my news area, and still be able to apply my CSS style to it.

(Additional info.)
On my ‘submittion’ page, it’s a simple php form that has two text areas, one for a title and one for the body of my article. In my stylesheet, I’ve created custom styles for the title and body, but I’m wondering if its possible to apply them, since i’m only retrieiving them rather than coding them into the html.

I hope this wasn’t too confusing. I’m trying to get a grasp on this before i actually settle out to do it. So can anyone give me an idea on how to do this, it can’t be that hard, I just can’t find any tutorials on it.
