使用 <label> 是一种好习惯吗?对于非输入/非交互元素? [英] Is it good practice to use <label> for non-input/non-interactive elements?

问题描述

When labeling a non-input element with no interactivity, such as a preview <img>, is it better (or correct) to use <span> instead of <label>?

e.g.:

<span>Image preview:</span>
<img id="preview">

or this:

<label for="preview">Image preview:</label>
<img id="preview">

解决方案

The <label> tag defines a label for an <input> element.

So use <span>instead.

The for attribute associates the label with a control element, as defined in the description of label in the HTML 4.01 spec. This implies, among other things, that when the label element receives focus (e.g. by being clicked on), it passes the focus on to its associated control. The association between a label and a control may also be used by speech-based user agents, which may give the user a way to ask what the associated label is, when dealing with a control. (The association may not be as obvious as in visual rendering.

HTML specifications do not make it mandatory to associate labels with controls, but Web Content Accessibility Guidelines (WCAG) 2.0 do. This is described in the technical document H44: Using label elements to associate text labels with form controls, which also explains that the implicit association (by nesting e.g. input inside label) is not as widely supported as the explicit association via for and id attributes,
