Based off of some basic HTML and LESS

I'm redesigning my personal website (more posts to come shortly!) and I was using a screenshot of some code in Sublime Text for a while but the graphic was too busy. It wasn't my screenshot so the code was someone else's too, and I felt weird about that. So today I sat down and created a simple, clean graphic to replace it!

I'd love to hear constructive criticism regarding layout, spacing, size, etc!

Thank you for your help!
