Describe the bug

  • When we resize an image with a class 'xyz', all the elements on the page with the same class also get resized because the editor adds height width CSS to those classes.
  • But when I remove all the classes from the image, the editor uses the id to set height width CSS.
  • I am loading a bootstrap template in the editor. Recording link: https://d.pr/i/27EgH2

Steps to reproduce:

  • Load bootstrap template for editing.
  • Add multiple divs with shadow class ex.(<div class='shadow'></div>)
  • Place an image in one of the div which has shadow class and then try to resize the image.
  • Notice all the divs moving/resized along with the image.
  • Expected behavior only image should be resized.
  • Using grapesjs-parser-postcss as well and added it in initialization code.
  • Passing the CSS & javascript URLs using canvas option.

init method:

grapesjs.init({
            container: "#gjs",
             .....,
            canvas: {
                scripts: scriptUrls,
                styles: styleUrls,
            },
            parser: {
                parserPostCSS,
            },
        });

Component-first styling By default, when you select a component in the canvas and apply styles on it, changes will be applied on its existent classes. This will result on changing of all the components with those applied classes. If you need the style to be applied only on the specific selected component you have to select componentFirst strategy in this way.

grapesjs.init({
 ...
 selectorManager: {
   componentFirst: true,
 },
})

Thanks for reporting this, @FaisalShaikhHA.

The issue with When we resize an image with a class 'xyz', all the elements on the page with same class also gets resized because editor adds css to those classes. appears to be a race condition or state management timing problem. This typically happens when component lifecycle events and DOM modifications overlap, creating an inconsistent state.

What to try:

  1. Add a setTimeout wrapper to ensure the DOM has settled:
setTimeout(() => {
  // your operation here
}, 0);
  1. Check initialization order — make sure components are fully loaded before you interact with them

  2. Use the editor's event system — listen to completion events:

editor.on('component:mount', (component) => {
  // safe to interact with component here
});

Recommended next steps:

  • Test with the latest GrapesJS version if you haven't
  • Provide a minimal reproducible example (CodeSandbox) — this helps the team identify the root cause faster
  • Include GrapesJS version, browser, and console errors in your report
