Iframe element style both domain host at different server

I want to style inside iframe element using js and HTML, Have any library or concept.

Hi @shrikant_Maurya and welcome to the community :wave:

Could you explain a bit more what your goals are? I don’t quite understand what you mean. Can you make an example?

Have a nice day,

Integrate Instagram feed with embedded code, I want to change style using css. But css not work on Instagram embedded code.

Thanks for the clarification.

Since you are trying to style an iframe from another domain (cross-domain) this won’t work. To inject style you would need to do it with JS, but the Same-origin Policy prevents that in your case.
This would only be possible if the parent window and the embedded page are on the same domain.
