Technical Documentation Page -I need your feedback, please

I finished my Technical Documentation Page:

But I do not like the look of the page with a small screen width. In particular, I made a great distance between articles. With it I have achieved that when I click on the appropriate menu item, the title of this article is at the top of the main-doc (sorry for my English)))

nice gradient! I would,

change hover link colors to something different that it gives more contrast to the background color.
Increase overall font-size.
Consider using different background-colors for your codes.

Good luck!

Just a personal opinion, butI would increase font size and let the background be still, may be just a plain background. Technical documentation tends to be confusing enough by itself, so I don’t need other things (that bring no clarification) calling my attention while I read it…
Its a nice website anyway :wink:
