Custom CSS Scrollbar for Firefox

Question

I want to customize a scrollbar with CSS.

I use this WebKit CSS code, which works well for Safari and Chrome:

::-webkit-scrollbar {
    width: 15px;
    height: 15px;
}

::-webkit-scrollbar-track-piece  {
    background-color: #C2D2E4;
}

::-webkit-scrollbar-thumb:vertical {
    height: 30px;
    background-color: #0A4C95;
}

How can I do the same thing in Firefox?

I know I can easily do it using jQuery, but I would prefer to do it with pure CSS if it's doable.

Would be grateful for somebody's expert advice!

Answer 1

May I offer an alternative?

No scripting whatsoever, only standardized css styles and a little bit of creativity. Short answer - masking parts of the existing browser scrollbar, which means you retain all of it's functionality.

.scroll_content {
    position: relative;
    width: 400px;
    height: 414px;
    top: -17px;
    padding: 20px 10px 20px 10px;
    overflow-y: auto;
}

Answer 2

I thought I would share my findings in case someone is considering a JQuery plugin to do the job.

I gave JQuery Custom Scrollbar a go. It's pretty fancy and does some smooth scrolling (with scrolling inertia) and has loads of parameters you can tweak, but it ended up being a bit too CPU intensive for me (and it adds a fair amount to the DOM).

Now I'm giving Perfect Scrollbar a go. It's simple and lightweight (6KB) and it's doing a decent job so far. It's not CPU intensive at all (as far as I can tell) and adds very little to your DOM. It's only got a couple of parameters to tweak (wheelSpeed and wheelPropagation), but it's all I need and it handles updates to the scrolling content nicely (such as loading images).

P.S. I did have a quick look at JScrollPane, but @simone is right, it's a bit dated now and a PITA.

It works in user-style, and it seems not to work in web pages. I have not found official direction from Mozilla on this. While it may have worked at some point, Firefox does not have official support for this. This bug is still open https://bugzilla.mozilla.org/show_bug.cgi?id=77790

scrollbar {
/*  clear useragent default style*/
   -moz-appearance: none !important;
}
/* buttons at two ends */
scrollbarbutton {
   -moz-appearance: none !important;
}
/* the sliding part*/
thumb{
   -moz-appearance: none !important;
}
scrollcorner {
   -moz-appearance: none !important;
   resize:both;
}
/* vertical or horizontal */
scrollbar[orient="vertical"] {
    color:silver;
}

Answer 4

There's no Firefox equivalent to ::-webkit-scrollbar and friends.

You'll have to stick with JavaScript.

Plenty of people would like this feature, see: https://bugzilla.mozilla.org/show_bug.cgi?id=77790

This report is asking for the exact same thing you're asking for: https://bugzilla.mozilla.org/show_bug.cgi?id=547260

It was closed as a duplicate of the first report I linked to.

As far as JavaScript replacements go, you can try:

• https://github.com/noraesae/perfect-scrollbar
• https://github.com/jnicol/trackpad-scroll-emulator
• https://github.com/vitch/jScrollPane (but it's outdated and apparently a PITA...)

@-moz-document url-prefix(http://),url-prefix(https://) {
    scrollbar {
       -moz-appearance: none !important;
       background: rgb(0,255,0) !important;
    }
    thumb,scrollbarbutton {
       -moz-appearance: none !important;
       background-color: rgb(0,0,255) !important;
    }

    thumb:hover,scrollbarbutton:hover {
       -moz-appearance: none !important;
       background-color: rgb(255,0,0) !important;
    }
    scrollbarbutton {
       display: none !important;
    }
    scrollbar[orient="vertical"] {
      min-width: 15px !important;
    }
}

Since Firefox 64, is possible to use new specs for a simple Scrollbar styling (not as complete as in Chrome with vendor prefixes).

In this example is possible to see a solution that combine different rules to address both Firefox and Chrome with a similar (not equal) final result (example use your original Chrome rules):

The key rules are:

For Firefox

.scroller {
  overflow-y: scroll;
  scrollbar-color: #0A4C95 #C2D2E4;
}

For Chrome

.scroller::-webkit-scrollbar {
    width: 15px;
    height: 15px;
}

.scroller::-webkit-scrollbar-track-piece  {
    background-color: #C2D2E4;
}

.scroller::-webkit-scrollbar-thumb:vertical {
    height: 30px;
    background-color: #0A4C95;
}

Please note that respect to your solution, is possible to use also simpler Chrome rules as the following:

.scroller::-webkit-scrollbar-track  {
    background-color: #C2D2E4;
}

.scroller::-webkit-scrollbar-thumb {
    height: 30px;
    background-color: #0A4C95;
}

Finally, in order to hide arrows in scrollbars also in Firefox, currently is necessary to set it as "thin" with the following rule scrollbar-width: thin;
