My first impression is that the pages seem washed out. I thought maybe there was a problem with the browser at first. Very plain too. Why not use black text instead of gray? This lack of contrast with a medium gray on white hurts my eyes. This is just a first impression, not a critique.
The webpage has a lot line space in the text box, making it hard to read, especially if someone types in their code its a lot of scrolling!
Also the extra space makes it look simple and white.
Yes to the black text ! I can change the text color, which is great.
