My site is a little off in other browsers

So I’ve been working on this site for awhile, and yesterday, I basically finished the homepage, besides a few things needed, like finishing the customer service interaction, replacing parallax images with the correct one, and etc. I created these tabs in the site, as a guide to whats next when scrolling, which looks great in the designer mode, but when I published the site, it didn’t turn out the way I thought it would. At least on mozilla, and internet explorer, the tab is separated from the section. Also my testimony has a slight spacing between each other.

Here is the preview link:

Also here is the actual site link:

Again this is very general (No way to give answer like this)

Sorry for the lack of information, I was seeking for help on how to keep the tabs from displaying a dividing line between sections on particular browsers, but I was able to find the solution to my problem. Thanks for reaching out.
