Help - extra space below my content

Hi everyone.
Would you mind having a look at this:
and telling me why on earth do I have that extra white space below my content? and why is my last div slightly overflowing?

Thanks so much in advance!

EDIT: Nevermind! It took a long time to update but when it finally did, it was working properly.

@VirginiaBalseiro … did you check it your body tag? the white space is a body… you can check it by giving background color to your body tag and you can see the difference with the violet div.
Or you can add more height to the violet div.
