如何用 CSS 让 div 高度随其内容展开？
原文:https://www . geesforgeks . org/how-to-make-div-height-expand-with-it-content-use-CSS/
height 属性用于设置元素的高度。height 属性不包含元素的填充、边距和边框。height 属性包含许多定义元素高度的值。高度属性值如下所示:
语法:
height: length|percentage|auto|initial|inherit;
属性值:
- 高度:自动；用于将高度属性设置为默认值。如果高度属性设置为自动，浏览器将计算元素的高度。
- 高:长；用于以 px、cm 等形式设置元素的高度。长度不能为负。
- 高度:初始；用于将高度属性设置为默认值。
- 身高:遗传；用于从其父元素设置高度属性。
例 1: 本例使用高度:auto 属性来显示内容。
