Caution If you want to make a style conditional, you have to do it while the style window is
still open for the first time. After the window closes, the Condition tab no longer
appears in the window.
Figure 243: Condition page for paragraph styles
When you create a conditional style, you are saying “in this condition make this style look like that
other style”. For example, “When typing into a footer, make this style look like the my_footer
paragraph style; when typing into a table, make this style look like the table_text paragraph style”.
In addition to setting the normal (unconditional) properties of the style, you need to define which
other style it will look like in different situations. You do this on the Condition page.
To set up a conditional paragraph style:
1) Define a new paragraph style.
2) Select all the paragraph properties for the style. Do not click OK!
3) Click the Condition tab.
4) Select the Conditional Style option.
5) Select the first condition in the Context list (left side of the dialog) and select the style you
want for this condition in the Paragraph Styles list on the right-hand side.
6) Click Apply. The name of the paragraph style appears in the middle list.
7) Repeat steps 5 and 6 for each condition you want to have linked to a different style.
8) Click OK.
When the style is selected, you will see that the formatting of your text depends on the context.
