由 人盡茶涼 提交于 2020-02-29 20:17:32
溢出属性： （重要） overflow :visible/hidden/scroll/auto/inherit 值 描述 visible 默认值。内容不会被修剪，会呈现在元素框之外。 hidden 内容会被修剪，并且其余内容是不可见的。 scroll 内容会被修剪，但是浏览器会显示滚动条以便查看其余的内容。 auto 如果内容被修剪，则浏览器会显示滚动条以便查看其余的内容。 inherit 规定应该从父元素继承 overflow 属性的值。 overflow-x:hidden; 隐藏横向滚动条 overflow-y:hidden; 隐藏纵向滚动条 文本单行显示省略号： 1.容器宽度: width:value;(px、%都可以） 2.强制文本在一行显示： white-space:nowrap; 3.溢出内容为隐蔽： overflow:hidden; 4.溢出文本显示省略号： text-overflow:ellipsis 来源： https://www.cnblogs.com/wjsblog/p/12384962.html
