1. class: used to specify one or more class names for elements, which can be used for style definitions in selectors and style sheets.

2. id: Specify a unique identifier for the element, which can be used for DOM operations in JavaScript and style definitions in style sheets.

3. style: used to specify inline styles for elements. CSS styles can be defined directly in the attributes of the element.

4. title: used to provide additional prompt information for the element, which will be displayed when the user hovers the mouse over the element.
