HTML <img> height 属性

❮ HTML <img> 标签

示例

高度为 600 像素,宽度为 500 像素的图像

<img src="img_girl.jpg" alt="Girl in a jacket" width="500" height="600">
自己试一试 »

The height 属性指定图像的高度,以像素为单位。

提示: 始终为图像指定 heightwidth 属性。如果设置了高度和宽度,则在页面加载时将保留图像所需的空间。但是,如果没有这些属性,浏览器将不知道图像的大小,也无法为其保留适当的空间。效果将是页面布局在加载过程中会发生变化(在图像加载时)。

提示: 使用 heightwidth 属性缩小大型图像会迫使用户下载大型图像(即使它在页面上看起来很小)。为了避免这种情况,请在将图像用于页面之前使用程序对其进行重新缩放。
