I have two applications running on the same origin/server like app.myserver.com and portal.myserver.com. I embed a page from app.myserver.com to the portal.myserver.com using <embed>. How can I change the css style for the embed page from portal.myserver.com i.e I need to change/override the css style of the app from portal.
template inside the portal.server.com is as following
<object id="app-page" data="app.myserver.com/page" width="100%" height="100%">
    Error: Embedded data could not be displayed.
</object>
I can see the ispect element of the portal.myserver.com like below
<object id="app-page" data="app.myserver.com/page" width="100%" height="100%">
  #document
  <!DOCTYPE html>
  <html>
  <head><title>Hello</title></head>
  <body>
  <div class="first-div"><p>lorem ipsum</p></div>
</object>
I'm open to use any javascript or jquery solutions
