Adds a fading gradient to an overflowing element to better indicate there is more content to be scrolled.

<div class="overflow-scroll-gradient">

CSS
.overflow-scroll-gradient {
position: relative;
}
.overflow-scroll-gradient::after {
content: '';
position: absolute;
bottom: 0;
width: 240px;
height: 25px;
background: linear-gradient(
rgba(255, 255, 255, 0.001),
white
); /* transparent keyword is broken in Safari */
pointer-events: none;
}
.overflow-scroll-gradient__scroller {
overflow-y: scroll;
background: white;
width: 240px;
height: 200px;
padding: 15px;
line-height: 1.2;
}
Output
Brief Explanation
position: relative on the parent establishes a Cartesian positioning context for pseudo-elements.
::after defines a pseudo element.
background-image: linear-gradient(...) adds a linear gradient that fades from transparent to white (top to bottom).
position: absolute takes the pseudo element out of the flow of the document and positions it in relation to the parent.
width: 240px matches the size of the scrolling element (which is a child of the parent that has the pseudo element).
height: 25px is the height of the fading gradient pseudo-element, which should be kept relatively small.
bottom: 0 positions the pseudo-element at the bottom of the parent.
pointer-events: none specifies that the pseudo-element cannot be a target of mouse events, allowing text behind it to still be selectable/interactive.
