Creating an HTML5 canvas that expands to cover the entire html document

After learning JavaScript, I decided to create a page on Github. Everything seems fine, except that the JS code for canvas doesn't scale to fit the entire HTML page. The particles only bounce off the initial window, leaving empty space when scrolling down. How can I adjust the JS canvas code so that the particle effect covers the entire page?

TLDR: How do I modify the JS code to make the particle effect span the entire HTML page instead of just the initial window?

Answer №1

It appears that the issue at hand is related to HTML and CSS rather than JavaScript. Despite setting your element with a 100% width, the body of your template might contain default padding. To address this, you can try the following steps:

<!-- HTML -->

<div id="my-canvas-container">
  <!-- This section is designated for loading your canvas -->
</div>



/* CSS */

html, body {
  padding: 0;
  margin: 0;
}

#my-canvas-container {
  min-width: 100%;
}
