I have been following Keith Clark's guide to CSS Parallax. His concept it like so:
HTML:
<div class="container”>
<div class="parallax-child”></div>
</div>
CSS:
.container {
width: 100%;
height: 100%;
overflow-x: hidden;
overflow-y: scroll;
perspective: 1px;
perspective-origin: 0 0;
}
.parallax-child {
transform-origin: 0 0;
transform: translateZ(-2px) scale(3);
}
This works perfect for the most part, for example on my development website. However I need to add this effect to another website where I can't control the HTML structure much at all, below is the basic structure tree, added comments to where I can edit.
<html>
<body>
<div itemscope itemtype="http://schema.org/AutoDealer">
<div id="main-wrap">
<div class="row">
<div class="main twelvecol">
<!-- Editable -->
<div>
<div class="row-block finance parallax__group">
<div class="parallax__layer--back parallax__layer">
<p>Content in here scrolls slower than everything else</p>
</div>
<div class="wrapper">
<div class="container">
<div class="parallax__layer--base parallax__layer">
<p>This is all of the top level content</p>
</div>
</div>
</div>
</div>
</div>
<!-- END Editable -->
</div>
</div>
</div>
</div>
</body>
</html>
I can add any styles I want, just can't edit the HTML structure apart from where stated in the comments.
My issue is I can't seem to get the parallax effect to work, if I put the example container styles for the parallax effect (at the top of this post) on the body the parallax effect works...
From what I have read I would need to add the transform-style: preserve-3d; style onto elements between the container and the children, however this doesn't appear to work.
Anyone know what's going wrong?
Edit:
Codepen of the working CSS on the body.
Codepen of the non-working CSS on the HTML.
Edit: Due to more complications with fixed positions and detecting body scroll (not possible it seems), I really need to get this working by using the HTML element.
What is strange, is that is sort of works. Follow this link and click and drag the slider left/right, the parallax effect is there, just not when you scroll down...
Not too sure why this effect doesn't work when you scroll down...
