<p>HTML Tag Attributes

<p>HTML attributes are an important tool for providing additional information about HTML elements. These properties can be used to set the element's behavior, appearance, or specify additional data.

<p>Attribute syntax

<p>HTML attributes use the form of attribute name and value pairs, separated by an equal sign. The attribute name is followed by an attribute value enclosed in double quotes or single quotes. For example:

<p style="color: red;">
  这是一段红色文本。
</p>
Copy after login
<p>Here, style is the attribute name, and color: red; is the attribute value. This property sets the color of the <p> element's text to red.

<p>Common Attributes

<p>Some of the most common HTML attributes include:

  • id: Uniquely identifies an element.
  • class: Group similar elements.
  • style: Set the style of the element.
  • src: Links to images, scripts, or other resources.
  • alt: Provides alternative text for the image (for accessibility).
  • title: Provides the element's tooltip text (displayed on mouseover).
  • href: Points to the destination of the hyperlink.
<p>Attribute value

<p>Attribute value can be a string, number, boolean, or enumeration (list of predefined options). For example:

<input type="text" name="username">
Copy after login
<p>Here, the value of the type attribute is text, indicating that this is a text input field.

<p>Attribute priority

<p>If an HTML element has multiple identical attributes, the CSS style has the highest priority, followed by the inline style, and finally the default element style .
