Display of a web page in a card

I would like a card when I can display a web page.
for example, with opensky I can get flight number but not starting and landing point. A web page would help
for example, every week I look the program of local movies and movies on 2 next cities, a web page would help.

We should be able to specified the dimension of the card.

This already exists.

Oh I am learning every day . I am sorry and thank you
