# Colons

Use colons to introduce unordered lists, tables, or images. Always precede lists, tables, and images with a full sentence. You can also introduce a list within a sentence.

Introduce tables with a complete sentence that describes the purpose of the table because not all screen readers preannounce tables. The introductory sentence can end with a colon or a period; usually a colon if it immediately precedes the table, and usually a period if there's more material (such as a note paragraph) between the introduction and the table.
