I wanted an embed Google Form in my website so i grabbed embed code and pasted it in my page.
<iframe src="https://docs.google.com/forms/d/1u1NO8u4vu6Q9XuUNigo4qy22hjvRmL-HFIRVsgiaL9c/viewform?embedded=true" width="760" height="500" frameborder="0" marginheight="0" marginwidth="0">Loading...</iframe>
(that's what Google gave me)
Everything is working fine BUT it's an iframe so I can't edit it's appearance using CSS. Google Docs' deafult themes don't match my site so I want to this page's CSS. I tried downloading https://docs.google.com/forms/d/1u1NO8u4vu6Q9XuUNigo4qy22hjvRmL-HFIRVsgiaL9c/viewform as html but this way I didn't get the css file. Do I have to create it by myself or there's another solution to my problem?
You can simply copy the form section of the html and copy paste to your page. It will post to google, and you still have full control over it.
You can't style it while it's an iframe.
