Font-related

Property	Description	Value type	Default value	Optional values	Syntax	Notes
font-size	Font size	Length unit	16px		font-size: 10px;
font-weight	Font weight	string	normal	normal, bold, 100, 200, 300, 400, 500, 600, 700, 800, 900. `normal` is equivalent to `400`. iOS supports all nine values. On Android, a value of `400` is rendered as `normal`, `700` or higher is rendered as `bold`, and values between 400 and 700 are rendered with a FakeBold effect.	font-weight: bold;
font-weight	Font weight	string	normal		font-weight: 700;
font-style	Font style	string	normal	normal, italic	font-style: normal;
font-family	Font family	string	Platform default font		font-family: PingFangSC-Regular;	Cross-platform consistency is not guaranteed. If the specified font is unavailable, the platform default font is used.

Layout-related

Property	Description	Value type	Default value	Optional values	Syntax	Notes
lines	Number of text lines	int	0, which means no line limit		lines: 10;
text-align	Text alignment	string	left	left, center, right	text-align: center;
text-overflow	Ellipsis style for overflowing content	string	clip	clip, ellipsis	text-overflow: clip;	`ellipsis` is currently supported only for single-line text. Note On some Android phones, the ellipsis may appear in the middle of the text. This is determined by the operating system.
line-height	Line height	Length unit + number	0		line-height: 12px;	If a number is specified, the value is `fontSize` × `value`. If a length unit with a `px` suffix is specified, the value is the `value` itself. If a percentage is specified, the value is `fontSize` × `value`.
white-space	Line break and whitespace policy	string	pre-wrap	normal: Whitespace is collapsed and text wraps automatically. Existing line breaks and paragraph breaks are ignored. nowrap: Collapses whitespace characters. The text does not wrap and is displayed on a single line, which can extend beyond the background box. pre: Whitespace characters do not collapse, line breaks occur between text segments, and text within each segment does not auto wrap (each segment is displayed on a single line and can extend beyond the background). pre-wrap: Whitespace characters are preserved, line breaks are preserved, and text wraps automatically. pre-line: Whitespace characters are collapsed, line breaks are preserved, and text wraps automatically.	white-space: nowrap;	-
word-wrap	Line break behavior, such as whether to break words	string	break-word	normal: Breaks lines at the end of words. Can extend beyond the background box. break-word: Breaks lines at the end of words. If the line is still too long, it can break within the word. anywhere: Can break lines at any point.	word-wrap: break-word:	-
word-break	Word breaking behavior at line breaks	string	None	normal: Words are not broken at line breaks. Can extend beyond the background box. break-all: Words can be broken at any point to wrap. keep-all: Same as `normal`.	word-break;	Does not differentiate between Chinese, English, and mixed Chinese-English text.
letter-spacing	Spacing between characters. Accepts positive or negative values.	string	0	normal: No extra space. Single value length unit: Can be positive or negative.	letter-spacing:5px;	-
text-indent	First-line text indentation. Accepts positive or negative values, or a percentage of the parent element width.	string	0	Single value length unit + percentage: Can be positive or negative.	text-indent:30%;	-
vertical-align	Vertical alignment of the text	string	baseline	baseline\|sub\|super\|length\|percentage\|top\|bottom\|middle\|top\|bottom Important The baseline is related to the font. Use this property with caution. `middle` aligns the middle of the element with the baseline of the parent plus half the x-height of the parent. `baseline` aligns the baseline of the element with the baseline of its parent. The HTML specification does not detail the baseline of some replaced elements, such as `<textarea>`. This means the behavior of these elements with this value may vary across browsers. `sub` aligns the baseline of the element with the subscript-baseline of its parent. `super` aligns the baseline of the element with the superscript-baseline of its parent. `top` aligns the top of the element and its descendants with the top of the entire line. `bottom` aligns the bottom of the element and its descendants with the bottom of the entire line. For elements that do not have a baseline, the bottom margin edge is used instead.	vertical-align:middle	-

color	Font color	Color unit	0x000000		color:red;
					color:#333;
					color:rgb(255,0,255);
text-decoration	Text decoration	string	none	underline, none, line-through, overline	text-decoration: underline;	-
text-shadow	Text shadow	Length unit & Color unit		Supports the format `${x} ${y} ${size} ${color}`. `x`, `y`, and `size` are length units, and `color` is a color unit.	text-shadow: 2px 2px 3px gray;	The color defaults to the font color. `x` and `y` are required parameters. Others are optional.
text-shadow-color	Text shadow color	Color unit	Same as `color`		text-shadow-color: blue;	Optional parameter
text-shadow-offset	Text shadow offset	Length unit		-	text-shadow-offset: 2px 2px;	Required parameter
text-shadow-radius	Text shadow radius	Length unit	0		text-shadow-radius: 3px;	Optional parameter

Differences from web

Key differences between Ant Dynamic Cards and web behavior:

Ant Dynamic Cards does not differentiate between Chinese and English text when handling `word-break`.
Ant Dynamic Cards does not differentiate between mixed Chinese and English text when a long word overflows the background box.

Web	Ant Dynamic Card
If `word-wrap` is not specified, the behavior is the same as `word-wrap: normal`.	If `word-wrap` is not specified, the behavior is the same as `word-wrap: break-word`.
`word-wrap: normal`: Words do not break and overflow the background box. A word is defined as a sequence of English characters.	`word-wrap: normal`: Words do not break and overflow the background box. A word is defined as a sequence of English characters and can include Chinese characters.
`word-break: normal`: Chinese text wraps to the next line. English words do not break and overflow the background box.	`word-break: normal`: Chinese text wraps to the next line. English words do not break and overflow the background box.
`word-break: keep-all`: Neither Chinese text nor English words wrap. They overflow the background box.	`word-break: keep-all`: The behavior is the same as `normal`.
-	`letter-spacing` is supported on Android 5.0 and later.
