Empty objects, frames that hold text and pictures, and lines are the fundamental building blocks of pages. InDesign's Tools palette contains several tools for creating these objects. The easiest way to create a text frame is by clicking and dragging a rectangle with the Type tool. After you create a text frame, you can enter text directly into it or import a text file, then modify the appearance of the frame or the text within. Similarly, after you create a graphics frame, you can import a picture into it and then crop, scale, or apply other effects to the graphic or modify the frame. The Line tool lets you draw straight lines, which you can modify by changing color , width, and style.
