Clipboard Landing Page Master

I got into some problems building the layout of the snippets section, so feel free to look at it and provide me with the best practice method to build this layout. Also, take a look at the footer and tell me if there's a better or easier way to build it. Last thing is that i feel the web page is much bigger in height than the actual screenshot of the challenge, i don't really know if that matters but if you had an idea about it then please leave a comment with the answer. Feel free to take an overview on the whole web page and correct my mistakes if there's any.
