How is it possible to change the style by a user input?

Question

/*var cng = prompt("width size")
document. getElementById("test").style.width""
*/ I am trying to put style.width"cng" but width is not being changed. It is being changed just by a number entry

Answer 1

getElementById("test").style.width = cng + "px"

Does this not work?
If not i might be on the wrong track and look into it again.
It would be nice if you could provide a code sample here on sololearn :)

Answer 2

I have tried it but the same size.

Answer 3

Thanks Dragonxiv it is working now
cng was in ""🙄

Answer 4

You have to add "px" after it.
Or any other size indication like "em" or others
