I've set a background image to an element but would like to tint it so that it is darker.
I'm trying to do it with multiple background images:
.c-to-c {
background: url('https://picsum.photos/535/250') no-repeat, rgba(0, 0, 0, .75);
background-size: cover;
}
The black doesn't show up however, and it's displaying as though there is only the background image.
If I understand your question correctly, then here is an example with linear-gradient
rule.
.c-to-c {
background: linear-gradient(rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5)), url('https://picsum.photos/535/250') no-repeat;
background-size: cover;
}
