Use CSS on embedded Forms/Views?

Use CSS on embedded Forms/Views?

Hello, how can I override the Zoho CSS stylesheets on embedded forms and views? I need to update my UI and unfortunately the Zoho styling is a little outdated.

I am tried to simply assign new CSS to specific Zoho classes in my html <head> but they aren't taking effect. I then did a "View Source" and copied the HTML/JS code into my own html page and was able to augment the CSS, but crucial Zoho functions stopped working.

Please let me know what I can do here, really considering using a different tool than Zoho for my form/database management if I am unable to change the style to something more modern. Thanks!
