When you are creating an area for your inline by using the third method of inserting inlines (in other words, by using the Object Creator buttons),
You can create an area it in your HTML file for the inline in one of two ways:
Note: If you hold down the shift key while dragging out a region, the aspect of the region stays the same as a square. Similarly, if you drag out a polygon, and then resize by clicking and dragging, you can maintain the original aspect ratio by holding down the shift key while dragging.
You can modify the size of an inline after it has been inserted with the Inline Attributes panel.
Notice that when you select an object creator, the cursor changes shape.
