Survey Add-On I can't see the selection

Hi,
I have installed the Survey Add-On and when I preview the form I can see the points for each selection correctly but when I include it in a web page I cannot see the selection. I understand that it may have to do with the CSS classes of the website but I am afraid that the developer who made it is no longer with us. I was wondering if there was a way for the form to avoid taking the classes from the website.

I opened this incident with Gravity and they told me the following:
The CSS added to your pages is not applied by Gravity Forms but by the browser, so which CSS rules are applied to your form elements is not something we can decide, it’s something the browser does.
Checking your page I see multiple CSS rules being added from your theme’s style.css file with very generic CSS targeting, so they apply to all elements in the page, for example.

I was wondering if anyone here could help me.

Thank you very much.
