Adding drop shadow and outline to links on cover page

Is there a way to add drop shadow and outline to link text on a cover page? I've added a custom logo to the cover page, but I'd like the links to match the styling and can't seem to figure out a way to do it.

Any help is appreciated!

.sqs-slide-wrapper[data-slide-type="cover-page"] [data-slice-type="navigation"] ul li a {
   color: #d7e5bd;
   text-shadow: 3px 3px #000000;
