The canvas is scalable if the parent's height is 100%

Question

The canvas is scalable if the parent's height is 100%

I am using particles to create canvas animations. The problem is, I need to make sure the section height #home

is 100% of the window, but when I do that, the canvas does not look as expected.

While using the following CSS rule technically works, I cannot use it because I need to set it $('#home').height($(window).height())

for some purpose later in my code.

html, body, #home {
  height:100%;
}

Snippet of code:

if ($('#particles-js').length > 0) {
    particlesJS('particles-js',
