get the width and lineheight of the character

[zundaren]

I have a container 800px wide and 800px high, how do I set the appropriate rows and cols to fill the container?
If lineheight*rows != height, the background color of xterm-screen should be filled

Your request is covered in #702. The standard way to do this is to use the builtin fit addon, here's example usage in the demo:

xterm.js/demo/client.ts

Line 281 in 9154831

addons.fit.instance!.fit();
