In this lab, we will learn how to add a fading gradient to an overflowing element using CSS. The purpose of this lab is to create a visual cue for users that there is more content to be scrolled. By using the ::after pseudo-element and linear-gradient() function, we can create a gradient that fades from transparent to white, indicating that there is additional content to be viewed.

Overflow Scroll Gradient

index.html and style.css have already been provided in the VM.

To add a fading gradient to an overflowing element and indicate that there is more content to be scrolled, follow these steps:

  1. Use the ::after pseudo-element to create a linear-gradient() that fades from transparent to white (top to bottom).
  2. Position and size the pseudo-element in its parent using position: absolute, width, and height.
  3. Exclude the pseudo-element from mouse events by using pointer-events: none, allowing text behind it to still be selectable/interactive.

Here is an example HTML and CSS code snippet:

<div class="overflow-scroll-gradient">
  <div class="overflow-scroll-gradient-scroller">
    Lorem ipsum dolor sit amet consectetur adipisicing elit. <br />
    Iure id exercitationem nulla qui repellat laborum vitae, <br />
    molestias tempora velit natus. Quas, assumenda nisi. <br />
    Quisquam enim qui iure, consequatur velit sit? <br />
    Lorem ipsum dolor sit amet consectetur adipisicing elit.<br />
    Iure id exercitationem nulla qui repellat laborum vitae, <br />
    molestias tempora velit natus. Quas, assumenda nisi. <br />
    Quisquam enim qui iure, consequatur velit sit?
  </div>
</div>

.overflow-scroll-gradient {
  position: relative;
}

.overflow-scroll-gradient::after {
  content: "";
  position: absolute;
  bottom: 0;
  width: 250px;
  height: 25px;
  background: linear-gradient(transparent, white);
  pointer-events: none;
}

.overflow-scroll-gradient-scroller {
  overflow-y: scroll;
  background: white;
  width: 240px;
  height: 200px;
  padding: 15px;
  line-height: 1.2;
}
