page misaligning in safari

[aliceinwonderla]

Hi! I have just noticed that my blog layout misaligns on Safari. You can see the difference between Safari and Firefox versions.

It only happens in pages, not posts or the main page.

What causes this? Is it my CSS? How do I fix it?

xxx Thanks you are always so helpful!!
