CSS Headache!

Hello!

I recently inherited this site http://www.complete-it.co.uk and I am having a bit of trouble with the CSS that controls the H2 and H3 tags.

At the bottom of every page is a widget that shows the latest blog article (why this isn't in the footer I have no idea!) and in the footer there is a contact form.

If you browse through the pages you will see that on some of them the 'COMPLETE I.T. BLOG' is in bold and on others it isn't. You will also see that 'meet or call you back?' is also in bold on some pages but not on others.

I cant figure out how to control this so that all the pages show these elements in bold and wondered if you could hep?

Thanks

Allan
