can you provide some example?

Yeah, that is doable with css custom-properties. When I get back coding I'll have a look in how we can provide this.

ahoy!! can I work on that??

@raxraj sadly assigned to @eltonmesquita... ;)

oh! I see, well I will keep trying then.

This didn't make into the v4.0.0 release, but I'll try to prioritize this feature in the next release (probably the next minor version).

@eltonmesquita looking forward!

Hello, I use animate in Vue. But the error has been reported all the time: what's the reason for cannot read property 'prefix' of undefined? Is there a similar solution

@wjxniubi please visit our documentation... https://animate.style/#migration

@wjxniubi请访问我们的文档... https://animate.style/#migration
Sorry, I used it for the first time. Some of them still don't understand

@wjxniubi !
Basically animate.css released a new version namely, v4.
Which has a breaking change and thus for now, if you don't want to continue migrating to the latest version just simply change your
import statement to

'import 'animate.compat.css';'

or if using HTML, which might be the case in VueJS.
Chane the link src as follows

  <link
    rel="stylesheet"
    href="https://cdnjs.cloudflare.com/ajax/libs/animate.css/4.0.0/animate.compat.css"
  />

@wjxniubi！
基本上animate.css发布了一个新版本，即v4。
它具有重大的变化，因此，现在，如果您不想继续迁移到最新版本，只需将您的
import语句更改为

“进口”动画。兼容。css ' ; '

或者使用HTML（在VueJS中可能就是这种情况）。
如下更改链接src

  < link 
    rel = “样式表”
     href = “ https://cdnjs.cloudflare.com/ajax/libs/animate.css/4.0.0/animate.compat.css ” 
  />

thank

@wjxniubi Happy to Help :)

@eltonmesquita any news on this? is this relate to our current project?

Nope, I'm pushing this as it's a bit of a laborious task. And no, it should be handled by animate.css.
