You can use USS to style a whole text string, but what if you only want to style one word of your text string? This is difficult with USS, but it’s simple with rich text tags.
Rich text tags are tags that you can place inside a text string to style the text between the tags.
For all the supported tags, see Supported tags.
Note: In the current release, rich text tags aren’t supported for TextField.
Rich text tags are similar to HTML or XML tags, but have less strict syntax.
A simple tag can have be just its name and have no additional values or attributes. For example, the <b> tag makes text bold.
Some tags have additional values or attributes like this:
<tag="value"><tag attribute="value">例
<color="red">: Makes text red<sprite index=3>: Inserts the fourth sprite from the default Sprite Asset.Note: In a UXML file, you must use HTML code for the following characters:
<: (<)
>: (>)
": (")
The following table lists possible attribute value types and example values.
| Value type | Example value |
|---|---|
| Decimals | 0.5 |
| Percentages | 25% |
| Pixel values | 5px |
| Font units | 1.5em |
| Hex color values |
#FFFFFF (RGB)#FFFFFFFF (RGBA)#FF (A) |
| Names | Both <link="ID"> and <link=ID> are valid. |
Tags have a scope that defines how much of the text they affect. Most of the time, a tag added to a specified point in the text affects all of the text from that point forward.
For example, if you add the tag <color="red"> to the beginning of the text, it affects the entire text block: <color="red">This text is red.
If you add the same tag in the middle of the text block, it affects only the text between the tag and the end of the block : This text turns<color="red"> red.
If you use the same tag more than once in a text block, the last tag supersedes all previous tags of the same type: <color="red">This text goes from red<color="green"> to green.
You can also use a closing tag to limit the scope of a tag, and use nested tag within another tag: <color=red>This text is <color=green>mostly </color>red
The first <color> tag’s scope is the entire text block. The the second <color> tag has a closing tag that limits its scope to one word.
When you nest tags, you don’t need to close their scopes in the same order that you started them.
Rich text tags are enabled by default.
To disable the rich text tag, do one of the following:
enable-rich-text attribute to false.
