Transparent scrollbar with css

问题

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;
}

回答1:

With pure css it is not possible to make it transparent. You have to use transparent background image like this:

::-webkit-scrollbar-track-piece:start {
    background: transparent url('images/backgrounds/scrollbar.png') repeat-y !important;
}

::-webkit-scrollbar-track-piece:end {
    background: transparent url('images/backgrounds/scrollbar.png') repeat-y !important;
}

    .scrollable-content {
      overflow-x:hidden;
      overflow-y:scroll; // manage scrollbar content overflow settings
    }
    .scrollable-content::-webkit-scrollbar {
      width:30px; // manage scrollbar width here
    }
    .scrollable-content::-webkit-scrollbar * {
      background:transparent; // manage scrollbar background color here
    }
    .scrollable-content::-webkit-scrollbar-thumb {
      background:rgba(255,0,0,0.1) !important; // manage scrollbar thumb background color here
    }

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.

<!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>

Best way to test it is to create a local html file, I guess.

You can also apply that on other elements, such as any scrolling box. While using inspector mode, it could be that you have to put the overflow to hidden and then back to anything else. It probably needed to refresh. After that it should be possible working on scrollbar without having to refresh it again. Just note that was for the inspector mode.

To control the background-color of the scrollbar, you need to target the primary element, instead of -track.

::-webkit-scrollbar {
    background-color: blue;
}

::-webkit-scrollbar-track {
    -webkit-box-shadow: inset 0 0 6px rgba(0, 0, 0, 0.3);
}

I haven't succeeded in rendering it transparent, but I did manage to set its color.

Since this is limited to webkit, it is still preferable to use JS with a polyfill: CSS customized scroll bar in div

Try this one, it works fine for me.

In CSS:

::-webkit-scrollbar
{
    width: 0px;
}
::-webkit-scrollbar-track-piece
{
    background-color: transparent;
    -webkit-border-radius: 6px;
}

and here is the working demo: https://jsfiddle.net/qpvnecz5/

Just set display:none; as an attribute in your stylesheet ;)
It's way better than loading pictures for nothing.

body::-webkit-scrollbar {
  width: 9px;
  height: 9px;
}

body::-webkit-scrollbar-button:start:decrement,
body::-webkit-scrollbar-button:end:increment {
  display: block;
  height: 0;
  background-color: transparent;
}

body::-webkit-scrollbar-track-piece {
  background-color: #ffffff;
  opacity: 0.2;

  /* Here */
  display: none;

  -webkit-border-radius: 0;
  -webkit-border-bottom-right-radius: 14px;
  -webkit-border-bottom-left-radius: 14px;
}

body::-webkit-scrollbar-thumb:vertical {
  height: 50px;
  background-color: #333333;
  -webkit-border-radius: 8px;
}

回答7:

if you don't have any content with 100% width, you can set the background color of the track to the same color of the body's background
