CSS white-space 属性用于控制元素中文本内部的空白流动。
可能的值
- normal:默认值,其中空格序列被折叠,当文本达到可用宽度时,文本换行到下一行。
- nowrap:空格折叠,文本不会换行到下一行。它在同一条线上继续,溢出可用宽度。
- pre:完全保留 HTML 代码中的空格。换行符和多个空格按原样显示。
- pre-wrap:保留 HTML 代码中的换行符和空格。
- pre-line:折叠空格,但保留换行符。当文本达到可用宽度时,文本将换行。
- break-spaces:折叠空格序列,但保留换行符并换行机会。这是一个实验值,可能并非在所有浏览器中都受支持。
- initial:将值设置为默认值,这是正常的。
- inherit:从其父元素继承值。
适用于
所有块级别元素。
