How do I achieve this layout

Hi everyone, I’m currently working on my website which is not yet online and I’m trying to get it look a certain way.

My website’s homepage has a banner, navigation bar, etc. all at the top of the page and I want my blog to be underneath with some information on the side.

I stumbled upon a users post in “Your WordPress” that had a similar layout of what I was trying to achieve (I’ve posted there as well).

Here is their website / blog and the thread where I found it:

How would I go about doing this. I am not new to HTML / CSS, but I am with embedding blogs. I recently purchased a domain that had a one-click install for WordPress.

Should I use that and simply copy paste my HTML code from my original page around it? Or manually install WordPress?

I’m new to embedding blogs and am wondering if I fiddle with the code to get it to look a certain way it well interfere with the functionality of the blog.

Any help appreciated, thanks.
