Choose Element→Style→New Style. New Style appears, as shown in
Figure 7‑1. The left side displays the property categories. The right side displays the properties for the category that you select.
To create a user-named style, specify a unique descriptive name for Custom Style. Ensure that the name is not the same as any of the predefined style names. If you specify a name that is the same as a predefined style, your custom style takes precedence, and you will no longer be able to use the predefined style to apply cascading styles.
