If the preferred font sizes were not set, the font size will be adjusted based on the maximum and minimum font sizes and the step you have set. If the maximum number of lines in the text cannot be met, text-overflow is used to truncate the text. If this parameter is set, font-size, max-font-size, min-font-size, and font-size-step do not take effect.

Example values: 12px,14px,16px

word-break6+

  • pre: All contents are output as-is.
  • pre-wrap: All contents are output as-is with line breaks.
  • pre-line: All spaces and tabs are combined into one space, the carriage return remains unchanged, and the text is wrapped.

adapt-height7+

boolean

false

No

Whether the text size adapts to the container height.

NOTE:

The settings take effect after font size auto-adaptation is configured.

NOTE:

  • In dynamic font adjustment, both the preset size set and the minimum/maximum font sizes are used to adjust the font size to display the text within the maximum number of lines. The preset size set is checked from left to right, and the minimum/maximum font sizes are checked from large to small, to find a size meeting the requirement.
  • Use the escape character \r\n for newline.
  • The following escape characters are supported: \a, \b, \f, \n, \r, \t, \v, \', \", and \0.
  • When you use <span> as a child component to form a text paragraph, note that if a <span> style is abnormal, the text paragraph cannot be displayed.
  • The letter-spacing, text-align, line-height, text-overflow, and max-lines styles take effect on text content held by the <text> component and its child components (<span>).
  • The <text> component does not support the coexistence of the text content and <span> subcomponents. (If both of them exist, only the content in <span> is displayed.)
