[Coca-code]

Hello,I have run it successful, but I can not set it's size. It's width is 250px; height is 250px. I want to use 'rem' units. How can I do in a 'Html \css\ js ' project? Thank you.

just change the values of 150,150 that is your width and height

@Coca-code I have not noticed this but what @jeraldkingn suggests seems to be correct.

@Coca-code Raphael itself does not seem to accept numbers in rem for the size of canvas. Would this work for you:

1. Create an element styled with width: Xrem; height: Yrem.
2. Get size of the element in pixel with JS.
3. Initialize Raphael-Rafar with the size you got above.
