QS:CSS Class
From LimeSurvey Manual
CSS class (css_class)
说明
如果你要在某些问题里添加特殊的 CSS 类,你可以在这个框里输入 CSS 类的名字。确保在每个不同的类名之间保留一个空格。
有效值
- 在 CSS 类名之间都有一个空格的任意字符串。
Hint: You can also insert an expression in this box (New in 3.0.0 ). Remember that the output of the expression will not be updated dynamically.
According to the W3C, CSS class names can contain only the characters [a-zA-Z, and 0-9] and ISO 10646 characters U+00A1 and higher, plus the hyphen (-) and the underscore (_). They cannot start with a digit, or a hyphen followed by a digit. LimeSurvey encodes CSS classes, but it does not fix it totally.
