To format text on your Google Site, such as making it bold, italicizing it, or creating headings, follow these steps:

• Bold: Enclose the text you want to make bold and select "B" bold text will display as bold text.

• Italics: Enclose the text you want to italicize with (I ). For example, italicized text will display as italicized text.

• Headings: Use the "Text box" tool to add headings to your site. Select the text you want to use as a heading, then choose a heading style from the toolbar (e.g., Heading 1, Heading 2, etc.).

You can also use the formatting options in the toolbar to apply these styles directly to your text.
