CSS issues?

Is there a ghost on my host?
I am really having trouble and cannot get around this issue. I ahve not touched my CSS file in sometime. I have been adding pages to my site for the past week.

All of a sudden the footer is overlapping with teh sidebar, pages that do not have content or not a lot the footere is under the text.

SO I go into the CSS modify the footer to get it to live at the bottom of each page. Then the footer sets itself at the bottom of page overlapping the sidebar.

I remove the content and it looks good not a fix but it works for now.

then the sidebar is off to the right. i remove the right align. now it is back.

Now my header content is off, and my navigation bar is overlapping my logo.

this has happened before to me and I intalled clear cache then these problems went a way, but that was when I created the template.

I am using the Engineering and Machinering theme. It doesn’t look like it anymore. i need to get my site working. it is living in dev area and my main site is down until i can resolve this.
