CSS calc() convert decimals to pixels
I'm trying to achieve css parallax effect via css-variables privided by scroll-out script.
Basically what script does - it sets --viewport-y css variable which I want to rely when calculating top value for image. The problem is --viewport-y values are decimals - e.g. 0.861, 0.034 etc
How do I get pixels value from this values?
I created snippet to demonstrate the issue where I changing opacity easily, but unable to set left property
body {
--test: 0.5;
}
.container {
background: yellow;
width: 100px;
height: 100px;
margin: 30px;
position: absolute;
opacity: calc( var(--test));
left: calc( 100 * var(--test))px;
}<div class="container"></div>css css-variables

Move px inside the calc expression, like this:
body {
--test: 0.5;
}
.container {
background: yellow;
width: 100px;
height: 100px;
margin: 30px;
position: absolute;
opacity: calc( var(--test));
left: calc( 100px * var(--test));

Using decimal values for px is perfectly fine. But the way you are using calc with units is wrong. You should do it as follows:
body {
--test: 0.5;
}
.container {
background: yellow;
width: 100px;
height: 100px;
margin: 30px;
position: absolute;
opacity: calc(var(--test));
left: calc(100px * var(--test));
}<div class="container"></div>The reason it works like that is that you can mix different units within calc. For example calc(100% - 10px).
