I'm trying to add a black rectangle as a bakcground for the red div.
I managed to make the horizontal hard fade:
background: rgb(0,0,0);
background: linear-gradient(90deg, rgba(0,0,0,1) 60%, rgba(208,6,30,1) 60%);
It seems it's either horizontal or vertical. Can I do both?
I'd like to do this with CSS, not add a black image as background.
If you set the background-color to the red you can overlay it with a rectangle of the black which has, say, 60% width and 50% height and is positioned from the bottom.
div {
--r: rgba(208, 6, 30, 1);
--b: rgba(0, 0, 0, 1);
display: inline-block;
width: 50vmin;
height: 30vmin;
background-color: var(--r);
background-image: linear-gradient(var(--b), var(--b));
background-size: 60% 50%;
background-position: left bottom;
background-repeat: no-repeat;
}
<div></div>
