I kind of like this repo, that's why I gotta criticize it:

This "app" should be (more) optimized for Arabic
It's border-right, not border left!

When scrolling, the preview and the editor sections don't go together.

In my humble opinion, running it on localhost is useless since it can be run simply by opening it in the browser (using the file protocol)

Also, consider linking to Arabic Wikipedia instead of the English one.
