Question

Hi @artf,

代码片段TEXT
I have added the 
           `let cc = editor.CssComposer;
           cc.setRule('.fadetop-animate', 
               { opacity: 0, 'animation-name': 'fadeTop' }, 
               {
                atRuleType: 'keyframes',               
                atRuleParams: 'fadeTop',              
                selector: 'to',
                style:{                 
                  opacity: 1
                }
              });`
as per the Document [](https://grapesjs.com/docs/api/css_composer.html#setrule)
however rule for keyframes is not getting added to the component.
how to add keyframes to the component style?

editor. CssComposer.getAll().add(`@keyframes fadeTop { ... }`) // Your CSS string

Thanks for reporting this, @niranjank151.

Great question about @keyframes not adding even after i pass the the keyframes object. The recommended approach with StyleManager is to use the event-driven API.

Start here:

  1. Check the GrapesJS documentation for your specific module
  2. Look for the on() event listener method
  3. Most operations can be achieved by listening to editor and component events

Common patterns:

// Listen for changes
editor.on('change', () => console.log('something changed'));

// Component lifecycle
editor.on('component:mount', (c) => console.log('component ready', c));
editor.on('component:update', (c) => console.log('component updated', c));

If you're still stuck:

  • Share a minimal CodeSandbox reproduction
  • Include what you've already tried
  • Mention your GrapesJS version
