If you want to sweep out a blank region for document formatting purposes, use the insert whitespace function in Cosmo Create. To create white space in your document:
Alternatively, you can just click the left mouse button where you want white space inserted, and a default amount (200x200 pixels) of whitespace is inserted. You can then modify the amount of space as you desire.
Cosmo Create creates a GIF file for that white space. You can modify the attributes of your whitespace with the Inline Attributes dialog, available through the Element menu.
Note: White Space is created in your HTML document by using an empty GIF file; the Netscape SPACER tag is not used.
