Try adding this rule to your custom CSS:
#nav li:first-child {
border-left: solid 1px #eee;
}
One tip: try not to use the !important clause with your property values. I see it used most often by beginning designers who don’t understand how CSS specificity works. The only time you really need to use it is to override an inline style, or if !important was used on a property that you need to override. Here’s a good article on when and how it should be used.
Perfect! Thank you so much. And I appreciate the tip – while I’m still a beginner, much of this modification work was done when I was an EXTREME beginner, thus the important clause. I’ll do my best to avoid in the future.
