Select one or more paragraphs, or click the text box, shape, or table cells with the text you want to change.
Note: Your changes only apply to the paragraphs or text selected. If you’re using paragraph styles in your document and want to incorporate the line spacing change in the paragraph style, drag past the last character in the paragraph to include the formatting symbol (it’s invisible until you drag over it).
In the Format sidebar, click the Style button near the top.
If the text is in a text box, table, or shape, first click the Text tab at the top of the sidebar, then click the Style button.
Click the disclosure arrow next to Spacing, then click the arrows for Before Paragraph and After Paragraph.
