How do I change the black color to transparent so that it is see-through?

Edit fiddle - JSFiddle - Code Playground

:root {
--color-a: #1155cc;
--color-b: black;
--color-c: #1155cc;
--color-d: black;
}

Maybe try "#00000000". That is see through black. If you want to see some black, change those last two 0's. What more might you be trying to do? JS can edit these variables. All those are in hex. X E.

Here is the way to achieve a transparent effect on a black color, depending on what you're working with:

If you're dealing with web elements or images, you can use the opacity property in CSS to control the transparency level. A value of 0 represents completely transparent, while 1 is fully opaque (black in this case). Here's an example:

CSS

.transparent-element {
background-color: black;
opacity: 0.5; / 50% transparent /
}

CSS

.transparent-element {
background-color: rgba(0, 0, 0, 0.5); / 50% transparent black /
}

I am trying to be able to place an image behind it where the gradient is see-through.
