The Pullquote Block allows you to highlight certain text. Pull quotes are short excerpts from your content. They're used to pull a text passage out of the content so as to highlight and provide a visual aid to your readers.
Once you've added your content to your Pullquote Block, there are further options available in the Settings Sidebar.
You can change the Text and Background colours, and various Typography settings like Font size, Appearance, Line height, Letter case & Letter spacing. You can also change the Border Width, Style, Colour and the corner Radius.
