Technical Support

I'm gearing up to get blogging again (lots of things to blog about!), but have been trying to give my blog a home makeover. When I view my blog on my PC, it looks fine, however, on my laptop, the header gets cut off by my blog posts. Is that what you are seeing? Do you have any tips/suggestions for how to fix this? I will look into it, but I thought one of my brilliant blogging friends may be able to help! Can't wait to blog to my heart's content!
