Answer 1

what is the difference between frame and iframe tag?

Answer 2

Ahmed Adel hi,
When you have doubts about what is supported, you can use "W3validator" site and check directly importing either your html (or CSS) file or directly by copy/paste your code, and they will give you a report with warnings and errors .
Also you can use "caniuse" site to check if browsers support or not elements you're using.

Answer 3

I didn't know frame tag was existing🙂.It seems it was a html4 version tag, not supported anymore and replaced by iframe.
