- In HTML, the id and class attributes are used to identify and group elements, primarily for styling with CSS and manipulating with JavaScript. The key difference is that an id must be unique within a page, while a class can be used on multiple elements
class Attribute
Must be unique to a single element in the HTML document.
Uses a hash symbol (#) (e.g., #header).
Higher specificity.
Only one id per element.
