particles.js not covering entire page


I'm trying to use particles.js as background, but I am not able to set the canvas as a full-size background.

I tried at least 10 different solution from similar issues but nothing worked. The canvas always results as as an element having width-height ratio as the screen but it doesn't cover it as a whole when it is resized. In addiction, it won't set as background but as a child of the body, over or below the remaining elements.

I simplified the code as much as possible and the problem still persist.

Example of the problem

HTML

<!DOCTYPE HTML>

<html>
    <head>
        <title>Try</title>
        <meta charset="utf-8" />
        <meta name="viewport" content="width=device-width, initial-scale=1.0, minimum-scale=1.0, maximum-scale=1.0, user-scalable=no">
        <link rel="stylesheet" media="screen" href="css/style.css">
    </head>

    <body>
        <div id="particles-js"></div>
        <div>
            <p>Something here</p>
        </div>
    </body>

    <script src="assets/js/particles.js"></script>
    <script src="assets/js/app.js"></script>
</html>

CSS

canvas{
  display:block;
  vertical-align:bottom;
  position: absolute;
}

/* ---- particles.js container ---- */

#particles-js{
  position: absolute;
  width: 100%;
  height: 100%;
  background-color: #b61924;
  background-image: url('');
  background-size: cover;
  background-position: 50% 50%;
  background-repeat: no-repeat;
  top: 0;
}

APP.JS and PARTICLES.JS can be downloaded from the owner's website posted before. I'm using themas they are at the moment

Thanks for any help


Solution

  • Ok I finally solved the background question: That's how I managed it (I'm pretty sure I had already tried that but re-building the whole html if finally worked)

    CSS

    #particles-js{
      width: 100%;
      height: 100%;
      position: fixed;
      background-color: #000;
      background-image: url('');
      background-size: cover;
      background-position: 50% 50%;
      background-repeat: no-repeat;
    }
    
    .body-particles{
      position: absolute;
      top: 0;
      left: 0;
      z-index: 100;
    }
    

    HTML

    <html>
        <head>
            <title>Title</title>
            <meta charset="utf-8" />
            <meta name="viewport" content="width=device-width, initial-scale=1" />
    
            <!-- SOME CSSs HERE -->
    
            <link rel="stylesheet" media="screen" href="assets/css/particles.css">
    
             <!-- SOME SCRIPTS HERE -->
        </head>
        <body>
            <div class="body-particles">
    
            <!-- Wrapper -->
                <div id="wrapper">
                    <!-- MY STUFF HERE, STYLED WITH MY CSS -->
                </div>
            </div>
    
            <!-- particles.js container -->
            <div id="particles-js"></div>
    
            <!-- scripts -->
            <script src="assets/js/particles.js"></script>
            <script src="assets/js/app.js"></script>
    
        </body>
    </html>
    

    Now, I have a new problem: being set as an underlying layer, it catch no pointer-events. As soon as I will make it works, I'll update the answer.

    Obviously, feel free to help if you have any suggestion.

    UPDATE: Workaround for mouseEvents: Adding class mouseEvents to elements I need to focus (for example , navbar, etc.)

    CSS

    .body-particles{
      pointer-events: none;
    }
    
    .mouseEvents{
      pointer-events: all;
    }
    

    However, it would be nice if someone knows a better way to keep events both in front and back layer
