Duplicated CSS while multi page creation

This is intentional and I'm not planning to change this behaviour as you can easily create specific CSS selectors if you need different styles per page. The big benefit of this approach is to allow reusing selectors across pages.

I think I'm experiencing an issue with this approach. I'm saving the pages to server like this:

const component = page.getMainComponent();
const css = editor.getCss({ component, avoidProtected: true }) 
saveToBackendApi(component,css)

and loading them like this in a loop:

const page = pageManager.add({
	name: pageName,
	component: pageHtml || `<div> ${pageName} </div>`,
	styles:css,
});

The css rules targeting ids are working fine, but the rules with a class are duplicating even when loaded in separate pages. For instance the # of css rules for .gjs-row class keeps increasing after after each save + load.

Thanks for reporting this, @gxanshu.

Great question about Duplicated CSS while multi page creation. 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));
