Question: How to use same CSS for Multiple pages

Hello Grapejs Team,

We've been working on Multi-page Website Builder.

For each project there will be multiple html pages with single common "style.css" page.

I am lazy loading each page with the following function - for handling multiple page loads

loadPage(pageId: string, cssPageId) {
    this.pageService.getEntity(pageId).subscribe(currentpage => {
      this.htmlPage = currentpage;
      this.editor.setComponents(currentpage.content);
    });
    this.pageService.getEntity(cssPageId).subscribe(stylepage => {
      this.cssPage = stylepage;
      this.editor.setStyle(stylepage.content);
    });
  }

The above page loads the page properly however, if page is empty or different from previous page it removes certain CSS classes. It's not perfectly loading the entire css file.

Am I missing something?

How can I have a common CSS file? Whether there is any workaround. Please help me with this issue.

Thanks for your great work and support :)
