I am using Notepad2 and Notepad++.
I think the Notepad++ editor is the best free code editor. Because it is so lightweight and its color schemes are very good colorized. I recommend it.
You have high quality images and good design, but I don’t like the footer.
You have poor typography on the footer.
The footer does not have enough quality like other sides.
The content is more complex, try to reduce it.
