Are there sites-catalogues of web interface elements with css hosting on their side?

Question

css

I don’t know if I formulated the question correctly, because I don’t understand anything in web development.

Here, let's say, I need to fasten an animated css button, but not on my site, but on a service that allows you to insert html codes. As I understand it from sites found by queries "css-button", these elements can only be used if there is access to the backend of the site in order to place css code there.

Or maybe there are services that provide all sorts of cool interface elements, including buttons, and at the same time host them so that it is enough to use only the html code?

Answer 1

If you can insert html, what prevents you from inserting code like this:

<style> 
div {
  width: 100px;
  height: 100px;
  background-color: red;
  animation-name: example;
  animation-duration: 4s;
}

@keyframes example {
  from {background-color: red;}
  to {background-color: yellow;}
}
</style>

<div></div>
