javascript - HTML content underneath WebGL animation not clickable -

-

i trying figure out why html content underneath webgl animation cannot clicked or interact with.

please see example.

currently div containing animation set to:

.webgl-glitch {     position: absolute;     z-index: 2;     overflow: hidden;     opacity: 0.5; }

..otherwise not display @ all.

i have tried setting z-index: 1; property on header/container div, not seem help.

here html section of header including animation div:

<!-- begin header animation --> <div class="webgl-glitch"></div> <!-- end header animation -->   <header id="principalheader" class="centercontainer aligncenter fullscreen tintbackground stonebackground" style="z-index:1">     <div>         <div class="container">             <!-- site logo-->             <a href="#" class="logo"><img alt="kubo" src="img/logo.png"></a>             <!-- site principal slogan-->             <h1>digital exploration the digital age</h1>             <!-- site resume-->             <div class="row">                 <div class="hidden-xs col-md-10 col-md-offset-1">                     <h2>craft experiences <strong>defy</strong> expectations<br/>                         create the twin <strong>virtues</strong> of inspiration , innovation<br/>                         beauty in simplicity , complexity <strong>combined</strong> best of both worlds</h2>                 </div>                 <div class="col-md-10 col-md-offset-1">                     <a class="fa fa-angle-down" href="#" data-scrollto="#about"></a>                 </div>             </div>         </div>     </div> </header>

another thing have noticed if wrap .web-glitch animation div inside html5 canvas element not display @ all? why be?

the property have on canvas in the css @ moment width: 100%;

it's not because of webgl animation, it's because of .webgl-glitch <div>. putting 1 html element on top of prevents 1 clicking whatever underneath it; doesn't matter if it's transparent or not.

as <canvas>: put inside <canvas> element supposed placeholder browsers don't support said element; if browser supports it, whatever put inside <canvas> ignored; so, if have this:

<canvas>     <h1>sorry, browser not support canvas element.</h1> </canvas>

on browsers not support canvas, message "sorry, browser not support canvas element." displayed user; on other hand, browsers support canvas not display elements inside canvas tag, , allow canvas operate normally.
