HTML5 supports a wide range of APIs. Some of the most popular ones include:

• Geolocation API, used to identify the user’s location
• Web Speech API, which provides speech recognition functionality
• Clipboard API, which provides copy, cut, and paste functionality
• History API, which provides access to the browser navigation history
• Web Notifications API, used to send web-based notifications to users

The ‘&copy’ code is used to generate the copyright symbol (©). As a best practice, it should be accompanied by a year and the name of the organization.

To include copyright information in the footer of a web page, the code would look like this:

<footer> <small>&copy; Copyright Date, Organization Name</small> </footer> 

HTML5 supports two types of web storage. These are:

1. sessionStorage: temporary storage available for the duration of the page session
2. localStorage: permanent storage available until data is deleted by the user
