Frame extending across page

Hi, I’m kind of new to HTML and I’ve been trying to make a website that has 3 frames in it. One frame extends across the entire top of the page and has about a 100 pixel height. The second frame extends the entire length of the page, but only has a width of about 200 pixels. Which leaves the rest for the thrid frame. I’m doing this so that frames one and two don’t change and all of the content changes in the third frame.

I’m running into an issue, because I cannot figure out how to get one frame extend across the top and one fram extend the length of the page. I can do one or the other but not both. is there any way that I can configure the columns and rows so that the page takes on this look?

Thank you.

here is a visual of what I’m trying to do:
