html - Transparent scrollbar with css

asked Oct 17, 2021 in Technique[技术] by 深蓝 (71.8m points)

Now use this code (and many variations of this), but scroll track get dark-grey color, something like #222222 or near this. Find many examples, but all of them give same result. Opera, Chrome and Firefox show this bug. How to fix?

#style-3::-webkit-scrollbar-track {
    -webkit-box-shadow: inset 0 0 6px rgba(0, 0, 0, 0.3);
    background-color: transparent;
}

#style-3::-webkit-scrollbar {
    width: 6px;
    background-color: transparent;
}

#style-3::-webkit-scrollbar-thumb {
    background-color: #000000;
}

If you use this:

body {
    overflow: overlay;
}

The scrollbar will then also take transparent backgrounds across the page. This will also put the scrollbar inside the page instead of removing some of the width to put in the scrollbar.

Here is a demo code. I wasn't able to put it inside any of the codepen or jsfiddle, apperantly it took me a while until I figured out, but they don't show the transparency, and I don't know why.

But putting this in a HTML file should go fine.

Was able to put it on fiddle: https://jsfiddle.net/3awLgj5v/

<!DOCTYPE html>
<html>
<style>
html, body {
  margin: 0;
  padding: 0;
}

body {
  overflow: overlay;
}

.div1 {
  background: grey;
  margin-top: 200px;
  margin-bottom: 20px;
  height: 20px;
}

::-webkit-scrollbar {
  width: 10px;
  height: 10px;
}

::-webkit-scrollbar-thumb {
  background: rgba(90, 90, 90);
}

::-webkit-scrollbar-track {
  background: rgba(0, 0, 0, 0.2);
}
</style>
  
<body>

<div class="div1"></div>

<div class="div1"></div>

<div class="div1"></div>

<div class="div1"></div>

<div class="div1"></div>
  

</body>
</html>
