HTML attributes are special keywords that provide additional information about HTML elements, modifying their behavior or appearance. They are always included within the opening tag of an element and come in the form of name-value pairs separated by equals signs. For example, in `<a href="https://example.com">`, `href` is the attribute name, and `"https://example.com"` is its value.

Attributes can be categorized into several types, including global attributes, event attributes, and element-specific attributes. Global attributes, such as `id`, `class`, and `style`, can be applied to any HTML element. The `id` attribute uniquely identifies an element, while `class` allows for grouping elements with shared styling or scripting. The `style` attribute directly applies CSS to an element.

Event attributes trigger JavaScript when an event occurs, such as `onclick`, `onload`, or `onmouseover`. These attributes are shorthand for assigning event handlers inline. For instance, `<button onclick="alert('Clicked!')">Click Me</button>` executes JavaScript when the button is clicked.

Element-specific attributes are unique to certain tags. For example, the `src` attribute in `<img>` specifies the image source, and the `alt` attribute provides alternative text for accessibility. The `type` attribute in `<input>` defines the kind of input field, such as text, password, or checkbox.

Attributes can be self-closing, such as `<img src="image.jpg" alt="Description" />`, where no closing tag is required. Boolean attributes, like `disabled` or `checked`, indicate the presence of a property without needing a value. For example, `<input type="checkbox" checked>` marks a checkbox as pre-selected.

Proper use of attributes enhances HTML structure, improves accessibility, and enables dynamic behavior through scripting. Following best practices, such as using semantic attributes and avoiding inline styles for maintainability, ensures cleaner and more efficient code.
