Legend Element: Caption for Fieldset Groups
The <legend> HTML element is used to provide a caption or title for a <fieldset> element, which groups related form controls within a form. The <legend> element enhances the accessibility and usability of forms by giving context to the grouped controls, helping users understand the purpose of the section. It is typically rendered as a block-level element that appears at the top of the <fieldset>.
Usage and Characteristics
The <legend> element must be the first child of a <fieldset> and is used to describe the grouping of form controls within that fieldset. This is particularly useful in complex forms where multiple sections need to be clearly identified. Here is an example of how the <legend> tag can be used:
<form>
<fieldset>
<legend>Personal Information</legend>
<label for="name">Name:</label>
<input type="text" id="name" name="name"><br>
<label for="email">Email:</label>
<input type="email" id="email" name="email">
</fieldset>
</form>Valid Attributes for <legend>
The <legend> element does not have specific attributes beyond the global attributes, which include:
| Attribute | Description |
|---|---|
| class | Specifies one or more class names for the element, used for CSS styling. |
| id | Defines a unique identifier for the element, useful for linking and JavaScript. |
| style | Contains inline CSS styles for the element. |
| title | Provides additional information about the element, often displayed as a tooltip. |
