Thank you for getting in touch.
A large part of the CSS we give out is to help with theme incompatibilities where our plugin and a theme have contradictory CSS. In theory this shouldn’t happen, however in practise it’s quite commonplace.
If you are able to link us to your map page then we can provide CSS to get that looking presentable in the very least,
If you do want to to know what classes each element uses, you can right click any element on the page and choose “Inspect” to view the element, along with all it’s classnames and other attributes.
Does that help?
