Why does the coder not recognize some elements?

Question

The coder section of this app is awesome however it doesn’t recognize certain elements when I try to implement them. For instance it did not seem to know what “inline” was. And it doesn’t have “flex” either.

I’m fairly new to coding so forgive me if I’m missing something obvious but does anyone have any insight on this?

Answer 1

This app is more of learning then coding so if you want to code you should be doing it on computer where its much easier if you have one.
