Preview of entered text on same page
I am delveloping a greeting card site and would like to have a preview option.
I want to set up an area that appears like the inside of a greeting card to show clients how their product will actually print. So, if they type into a text field it would appear in the area of the card as a greeting in the proper font and size. Or when a customer chooses an option from a select list it would automatically display an image example of how the actual card imprint will look.
Is is some sort of repeating region?
Any guidance? I have no clue where to start.
