📜  CSS |空白属性

📅  最后修改于: 2021-08-30 10:31:46             🧑  作者: Mango

CSS 中的white-space 属性用于控制文本换行和 white-spacing。此属性中有多种类型的值可供使用。

句法： 

white-space: normal|nowrap|pre|pre-line|pre-wrap|initial|inherit;

属性值：

  • normal：这是该属性的默认值。当 CSS 的 white-space 属性设置为 normal 时，每个两个或多个空格的序列都将显示为单个空格。元素中的内容将在必要时换行。
    句法： 
    white-space : normal;

    例子 ：
