# Colons

Last updated Aug 20, 2026|Copy as Markdown|[View as Markdown](https://developers.cloudflare.com/style-guide/style-and-grammar/grammar/punctuation-marks-and-symbols/colons/index.md)|[Agent setup](https://developers.cloudflare.com/agent-setup/)

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.
