what is the recommended way to override aem ootb stylesheet?

I think we cannot overlay clientlibs in aem,  all clientlibs which has same category will be loaded.

If you just want to change a single style then create a new clientlibs with category cq.authoring.dialog and add css rule for background

/* placeholder */

.cq-Overlay .cq-Overlay--placeholder {

     background-color: rgba(255,255,255,.25);

  }

Hi Arun,

I have created a new clientlibs, under that created new less file and add the above code.

cq.authoring.dialog i have added as dependency in my clientlibs, but still it is loading from libs.

Please let me know  how to resolve this issue.

Thanks,

Kiran

could you please let me know which page you are checking?Is it site console or editing page?

I am checking page edit

Hi Arun,

Thank you for looking into this issue. I am checking at page edit. If you need any further information let me know?

Thanks,

Kiran

I am trying in 6.3, works for me.

It could be caching issue, could you please clear browser cache or try in incognito mode.

If doesn't work try with

?debugClientLibs=true

Agreed with Arun. Instead of overlaying file, creating a custom clientlib is cleaner approach. That way you would be upgrade safe.

kiranv43511543​ Overlaying of OOTB should be avoided to reduce tech debt to AEM upgrades . Recommended way is to create a separate client lib with just one css as mentioned by arunpatidar26​. Just make sure, the client lib category is same as of the OOTB client lib which you want to change. As long as you follow it, it will work for you. For this case, the correct category is - cq.authoring.editor.core, cq.authoring.editor
