What does this mean_html/css_WEB-ITnose

When I was studying CSS3 recently, I saw this piece of code,
@-moz-keyframes labelON{0%{top: 0px;
left: 0px;
}
100%{ top: 0px;
left: 38px;
}
}
I don’t know what it means, please give me some advice.

I don’t quite understand what those selectors should be before {}, but they don’t look like it!

@-webkit-keyframes labelON{	0%{top: 0px;    left: 0px;	}		100%{top: 0px;    left: 38px;	}}

The complete code is like this

It’s so unpopular

Hurry up and post it, hey, actually this is the key frame technology in CSS animation.
