I want to add a button (or rather, a link formatted to look like a button) in the utilities area somewhere above the main navigation menu of a WordPress-based business site (that is, not in the body of a post or page). The purpose of the link is to enable the website visitors to download the company's annual report to their computers, either from media library, or from some other directory on the server.
I found some information among earlier WordPress Answers, but still couldn't figure out the best way to do what I need to be done.
Just to explain what I mean: I'm not asking how to place a link into a page. What I want to learn is how to force a file download onto a user's computer. Apparently, there are plugins that allow you to do that, but they all end up with a link in the body of the post. What I want is a link in the website's header.
Would be grateful for assistance!
