Extra Page Styling

Hello again

I'm trying to edit my default "About" page and use the code area to write my HTML/CSS into.
When I click "Update" it looks fine but when I open the actual page in the browser, it' all changed. Even the code I wrote into, it's all changed.

Any idea what I need to do, because in admin editing it looks all good, on the server it's everything over written ! ? !

I have attached some screenshots that show the differences.
On the ma-admin-2 image I have added a background colour so you can see the col html works fine. Why it is all overwritten on the server, this puzzles me (see the code change in the ma-server attached image.

Thank you
