This snippet allows you to create a link or button on the page that opens a pop-up window displaying text. The pop-up can include headings, links, and images.
Please refer to here to build a pop-up. The below is legacy and may not work as expected.
Interested in having a pop-up on your webpage, similar to what you see when you click here? This tutorial will help you to accomplish such a task. However, I will warn you now, that this will require some HTML knowledge.
Locate the page/highlight in the CMS that should have the pop-up and edit said item. In the TinyMCE editor make a new line at the bottom of the content, this area will be the location of your new pop-up. With the new line created, from the “Format” dropdown in the styles bar, select “Blocks” and “Div” from the submenu. This will create a block that will wrap the content of your pop-up and is the actual pop-up content.
You may place images, headings, videos, and most anything that you would normally slot into the rest of the page inside of this div.
