Lightbox

Hello,

I’m wondering if anyone could help me with adding some simple CSS to a live editor. I would like to add a modal to a button when clicked to make a lightbox.

Here is the website [ redundant link removed ] the button is “The Full Story”

What code would I add in “On Click”? screenshot here: https://scontent.fper2-1.fna.fbcdn.net/v/t1.0-9/34120056_1747234108703271_2066048418073018368_n.jpg?_nc_cat=0&oh=6ba8688fe9893f653e54000c28bf7a1b&oe=5BA7A5DA

Any help would be greatly appreciated.
