Overlay/Lightbox Effect
Hello,
Is it possible, for me to create a button that opens an image without having people leave the website.
Basically, I would like for visitors to click on a button and when they do an image will pop up.
Also, I am very confused on the button shortcodes. How do I know exactly what code to type in? For example, a button with icon , where can I find that exact code?
I went to http://themes.muffingroup.com/betheme/shortcodes/typography and went down to where the buttons are then right clicked "inspect element", but I don't believe I am quite sure exactly what part of the code I should copy. So If you can provide the code for button with icon, I can probably figure it out. Unless you have detailed instructions somewhere

as we understand, you refer to popup shortcode. You can find this shortcode under wordpress editor where []+ button is.
