Try using the developer console to find/locate whatever element is giving you problems: right-click it and inspect > the console will tell you what selector to use in the styles pane.
Still having problems? Try transferring the problematic parts (just the pertinent CSS and HTML) to a reduced CodePen demo.
Unfortunately, as it stands, folks won’t want to go inspecting your website on your behalf because A) it’s difficult to decipher what you want, or have tried, from your description, and nobody likes to guess, B) wading through a whole website codebase is distracting and takes too much effort, and C) you’re a first-time poster and the link looks like self-promo spam.
