I´m working on a website with a CMS tool. I want to change the background of an image preview, which is in css code this:
.mfp-container {
background: rgb(222, 222, 222);
}
So it's a really basic code, I just want to adjust the color. My CMS Tool works with css variables and I never worked with those and really have no idea how to get a variable out of this.
Does someone know how to get one out of this basic code? Or is there any formula to "convert" it?
