I'm also having trouble making my last item on my nav into a button, i've copied different codes from multiple sources including this one and nothing seems to be making the item turn into a button of any sort.
This is the website: https://www.danceathaven.com/
I want to turn the "PARENT PORTAL" into a button that acts/looks like the "Register Here" button or just has a box around it like the register here button. Is there a specific code that could help me?
