How to set canvas height to be Full Document height (Cover the whole page)

Question

Heyy all,

Just getting ready for xmas so I had some snow falling using the Canvas and it looks really cool, although it is only fulling up via 100vh due to:

c.width = innerWidth;
c.height = innerHeight;

So if someone could help me out here I would much appreciate it =)

I have tried using via CSS:

canvas#c {
position: absolute;
z-index: 999;
bottom: 1px;
top: 1px;
height: 100%;}

Answer 1

For anyone who cares, I changed from position: absolute; to position: fixed;

Now it just stays in the screen looking like its snowing =)
