List of CSS vendor prefixes?

Besides the following list, are there other CSS vendor prefixes that are important for web development? Are my definitions correct? Should I be more specific about mobile browsers (mobile Webkit, e.g.)

• -khtml- (Konqueror, rea开发者_开发问答lly old Safari)
• -moz- (Firefox)
• -o- (Opera)
• -ms- (Internet Explorer)
• -webkit- (Safari, Chrome)

Does this list (which also contains mso-, -wap-, and -atsc-) add anything of value?

These are the ones I'm aware of:

• -ms- Microsoft
• mso- Microsoft Office
• -moz- Mozilla Foundation (Gecko-based browsers)
• -o-, -xv- Opera Software
• -atsc- Advanced Television Standards Committee
• -wap- The WAP Forum
• -webkit- Safari, Chrome (and other WebKit-based browsers)
• -khtml-, -konq- Konqueror browser
• -apple- Webkit supports properties using the -apple- prefixes as well
• prince- YesLogic
• -ah- Antenna House
• -hp- Hewlett Packard
• -ro- Real Objects
• -rim- Research In Motion
• -tc- Tall Components

These are officially listed in the CSS 2.1 Specification, informative section 4.1.2.2.

While not in the direct context of web development, JavaFX uses a vendor prefix for its use of CSS as well: -fx-.

Just a suggestion, if you're planning to just prefix add a css transition, let's suppose column-count: 3; and you want support for all major browsers, and you prefix your property with all the prefixes mentioned in answers here, then a better and more optimal way would be to use a tool that do this for you:

Input

a {
  column-count: 3;
  column-gap: 10px;
  column-fill: auto;
}

Output

a {
  -webkit-column-count: 3;
     -moz-column-count: 3;
          column-count: 3;
  -webkit-column-gap: 10px;
     -moz-column-gap: 10px;
          column-gap: 10px;
  -webkit-column-fill: auto;
     -moz-column-fill: auto;
          column-fill: auto;
}
