Remove CSS inside the iframe

Navigation
1

Hello, I have a page and I'm displaying it in an iframe, I want to create it as if it were a version 2 of the page with another style, so I want to remove the css from it and add another one without having to edit the style.css file, because I also want to keep the v1 page with the same style. Help me, it's in the same domain.

You can access the elements of iframe by using, for example, id of iframe : 

<iframe id="frame" width="500" height="200" src="pagina.php"></iframe>

<script>
    var iFrame = document.body.querySelector("#frame");

    iFrame.onload = function(){ // aguarda o iframe ser carregado
        // altera a cor do texto da #div1 dentro do iframe
        iFrame.contentWindow.document.querySelector("#div1").style.color = "red";
    }
</script>

Using iFrame.contentWindow you can access elements with querySelector or another way to select elements you want.
