Plugin does not respect HTML formatting

This test page https://www.mpba.org.uk/ztest-popup/. The popup is supposed to look like the 2nd one

Dear @mpbaweb,

We checked your site URL and noticed that your theme is affecting the styles on your pages.
This is why the popup formatting is also distorted.
Please, contact your theme developers and report them about this issue so they can fix it.

Ok. Did that. The theme developers said there is a css reset (Whatever that is) and you need to provide the css for the element

Dear @mpbaweb,

Can you, please, try to copy the popup content, and paste it into a plain page, out of the popup?
Please, check the results and let us know.

Please refresh the url:

See bottom section

The issue is that my theme is doing a ‘CSS Reset’ for anything other than Pages and Posts, so the popup element is not being styled. The styling is taken into account in the bottom section of the page in the above URL as it is not wrapped in the popup.

Dear @mpbaweb,

Please, contact us so we can offer a solution with the styling on your site.

All the coding in the popup is displayed just as like on your site.
So, if the styling in the popup is reset, it’s reset on your site as well.
