View webpage source code.

Viewing webpage source code refers to the process of inspecting the HTML code of a webpage. This code contains information of how the webpage is structured and displays its contents, such as text, images and multimedia elements. To view the source code of a webpage, users using most web browsers can right-click on the webpage itself and select "View page source" or "Inspect". This allows advanced users to delve deeper into the underlying structure of the webpage, which can be useful for debugging purposes or gaining a better understanding of how websites are designed and constructed.
