Safari Books Online is a digital library providing on-demand subscription access to thousands of learning resources.
The text frame itself has many formatting options. You can create columns directly inside a frame, choose a border stroke and customize it, fill the frame with color or a gradient, alter the shape, and much more. This book can’t cover all the possibilities, but here are some techniques to get you started. Chapter 7 on Graphics has more details about strokes and fills, and Chapter 8 on Color has all the details on creating and choosing colors.
Every frame has a stroke (the default is “None” so you don’t see it) and a fill (also “None”), but you can change those when appropriate.
1 Create a frame with text, or use one of the frames you’ve already created.
2 With the black Selection tool, click on the frame to select it.
