How to add css using jquery into iframe?

You can add CSS styles to elements within an iframe using jQuery by accessing the contents of the iframe and using the contents() method to manipulate the CSS.

Here's an example code snippet on how you can add CSS to elements within an iframe using jQuery:

// Select the iframe element
var iframe = $('iframe');

// Get the document object of the iframe
var iframeDoc = iframe.contents();

// Add CSS styles to elements within the iframe
iframeDoc.find('button').css('background-color', 'blue');
iframeDoc.find('h1').css('color', 'red');

In this example, we are selecting an iframe element using jQuery, accessing the document object of the iframe using the contents() method, and then using the find() method to target specific elements within the iframe and apply CSS styles to them.

Remember that you need to make sure that the iframe source is from the same domain as your website, as cross-origin security restrictions may prevent you from accessing the contents of the iframe.
