I'm using my wordpress blog as a website. I'm not sure what the terminology is, but I'd like to have an info button that I can place next to a word or phrase that requires a definition so that when clicked or hovered over a pop up box will appear with the definition rather than being linked to a page or a post. Or if that's not possible, can i have a post that this info button can be linked to but will not show up on with my actual blog posts? Thank you!
The blog I need help with is spinestrong.wordpress.com.
