CSS max-height屬性用法及代碼示例

它設置元素內容框的最大高度。這意味著內容框的高度可以小於 max-height 值，但不能大於。它設置元素高度的上限。

當內容大於最大高度時，就會溢出。如果內容小於 max-height，則該屬性不受影響。該屬性確保 height 屬性的值不能大於 max-height 屬性的值。它不允許負值。

有時將元素的高度限製在某個範圍內很有用。

用法

max-height:none | length | initial | inherit;

此 CSS 屬性的值定義如下。

none:它是不限製內容框大小的默認值。

length:該值以 px、cm、pt 等為單位定義 max-height。

initial:它將屬性設置為其默認值。

inherit:它從其父元素繼承屬性。

現在，讓我們看一個這個 CSS 屬性的例子。

示例

在這個例子中，有四個帶有內容的段落元素。我們使用 max-height 屬性的長度值定義這些段落的 maximum-height。第一段最大高度60px，第二段6em，第三段130pt，第四段5cm。

第一段的內容大於 max-height 屬性的值，所以在輸出中，我們可以看到第一段的內容溢出了內容框。
