Thank you so much.

But that won't achieve the effect I want！

I add 4*5=20 shapes in document and each shape has word on it.


Below is my sample pic:

card.jpg - Google Drive


The effect I need is that when I cilck one of the shapes,the shape will change to another color.
If I use content control,it seems that I Can't put the shapes where I want.
Though I can put a picture in a "wdContentControlBlockPicture",but I can't add some words just up on it.
Or if I use content control(wdContentControlRichText),may I change it's background color ?

Do you have any suggestion?

Thank you!
