Getting the pop-up to work on click

Hi,

The website I am currently developing needs to have pop-ups through the site to add more text and images without having to build additional pages. I've already purchased your Pro version and so have access to all features.

Therefore, I want to add a pop to a 'Read more >>' button. On click the pop-up will launch and display.

Can this be done without having to insert code. My client will be updating this site themselves and won't understand the concept of coding. Therefore I want to make this as easy as possible for them to understand.

Can you please help me out.

Thanks

Emma
