The Verse Block allows you to add poetry to your content. The Verse block is almost identical to the Preformatted Block in that it respects your spacing and tabs.
Once you've added your text to your 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 spacing around the block by adding Padding within the Dimensions settings.
