Rich text markup

UI rich text utilizes simple markup tags to style sections of a string in bold, italics, underline, fill color, stroke variations, and more. You can apply styling tags to TextLabel, TextButton, and TextBox objects.

Enable rich text

You must enable rich text on a per-object basis through its RichText property in the Properties window, or by setting the property to true in a LocalScript.

local title = Instance.new("TextLabel")
title.RichText = true

title.Text = "Use a <b>bold title</b>"

Note

When editing an object's Text property in Studio, toggling the RichText checkbox in the Properties window displays the text string as a final render. This is useful for identifying and correcting mistakes in any supported tags.

Note

Localizing a game to support other languages removes rich text formatting tags. To ensure formatting appears in other languages, re-apply the tags manually to your localized strings.

Supported tags

Rich text tags are similar to XML/HTML tags and you must include both an opening and closing tag around the formatted text.

<b>Formatted text</b>

You can also nest tags inside each other as long as you close them in the reverse order of how you opened them.
