The source code of a webpage is the underlying code that is used to create the webpage. It is the HTML, CSS, and JavaScript code that is used to define the structure, layout, and functionality of a webpage. A webpage source code can be viewed by using the "View Source" or "View Page Source" options in the browser's menu. The source code of a webpage can be useful for a variety of purposes, such as for learning how a webpage is built, troubleshooting website issues, optimizing website performance, and identifying potential vulnerabilities.
Developers and web designers use the source code to inspect the structure and layout of a webpage, to understand how different elements are created, and to check how the website is functioning and how it is optimized. It can also be used by security professionals to identify potential vulnerabilities and potentially malicious code.
There are also a few browser extensions and online tools that allow you to view the source code of a webpage without having to manually access the browser's menu option.
