Embed CMS within website

Is there a way to embed a CMS within an already existing website?

Currently my site is set up with a static header, sidebar, etc. The center of the page (content section) is just a php include file. I would like to have a CMS take the place of the content section, so that I can post articles, etc without having to totally re-do the header and whatnot for the CMS.

The site is http://www.miamidolphinsposters.com

Basically, the center section where the posters are now I would like to replace with a content management system that I can use for posting articles and whatnot, while leaving the rest of the page untouched.

Is this possible? If so, with what CMS?

 

The way it's usually done is to match the CMS to the website. 2 things cannot occupy the same space. when you see sites with CMS like wordpress that seem to be embedded, what is actually happening is that they have configured, color matched and duplicated the look of the website for the CMS.

I could be wrong, but I am going to say that you cannot simply embed a code below the existing header and have a CMS. You need to customize the CMS to match the website.

 

I was actually able to find one that was designed to do exactly what I was looking for:

I'm using it now down on the bottom of my site: Miami Dolphins Posters

 

Good for you. Never heard of it, but if it gets the job done and does what you need, that's all that matters.
