HTML <input> height 属性

❮ HTML <input> 标签

示例

将图像定义为提交按钮,并带有高度和宽度属性

<form action="/action_page.php">
  <label for="fname">姓:</label>
  <input type="text" id="fname" name="fname"><br><br>
  <label for="lname">名:</label>
  <input type="text" id="lname" name="lname"><br><br>
  <input type="image" src="img_submit.gif" alt="Submit" width="48" height="48">
</form>
自己试试 »

定义和用法

The height 属性指定 <input> 元素的高度。

注意:height 属性仅用于 <input type="image">

提示: 始终为图像指定 height width 属性。如果设置了高度和宽度,则在加载页面时会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,也不能为其保留适当的空间。效果是页面布局会在加载过程中发生变化(在图像加载时)。


浏览器支持

表中的数字指定完全支持该属性的第一个浏览器版本。

属性
height 16.0

语法

<input height="pixels">

属性值

描述
pixels 以像素为单位的高度(例如 height="100")
