Practice problem: Click behavior

[GitSmoosher]

In this activity's step 3 called "Get started", at the very bottom there is a section called "Add visual polish" in it we can read the following

" Give the BUTTON an accent color and slightly ROUNDED corners to let the users know that they can tap the image."

In what previous activity along the units and paths up to this point did you teach the reader how to ROUND corners of a button let alone how to add an image to a button?

To add image in the button, you just nest the Image compose inside the Button.

As for visual polish, these things are for you to explore and research about yourself. It is to promote self learning and creativity.
