Huddle Responsive Landing Page - BEM, Mobile First

Hi Everyone, Input and feedback on my code and how it can be improved will be greatly appreciated!

I did also have the following question that I couldn't figure out the answer to.

• Why is there a scrollbar where there's a slight scroll to the page where it shouldn't exist? I tried figuring it out and realized that things were overflowing from the body. From what I can tell, it seems to be because of the container div I wrapped everything with but I can't figure out what exactly I'm doing to make things overflow. Any input would be appreciated.
• I realize that I can set an overflow: hidden to the body to make it go away but it seems like a poor solution but if you think that's not the case, I'd love to hear your opinion.
