Live Server is a popular extension for Visual Studio Code (VSCode), a code editor developed by Microsoft. Live Server is designed to simplify web development by providing a local development server with live reloading capabilities. Here are some key features of Live Server:

1. Local Development Server:

   • Live Server sets up a local development server on your machine, allowing you to run and test your web applications locally.

2. Live Reloading:

3. Support for Static Files:

   • Live Server supports serving static files like HTML, CSS, JavaScript, images, and more. It helps you quickly preview your web pages during development.

4. Support for Dynamic Pages:

   • It works well with dynamic pages and applications, making it a useful tool for both static and dynamic web development.

5. Browser Compatibility:

   • Live Server is designed to work with various web browsers, ensuring a consistent development experience across different platforms.

6. Easy to Use:

   • It's easy to set up and use. Once installed, you can start the server with just a few clicks, and it will handle the rest.

To use Live Server with Visual Studio Code:

1. Install the "Live Server" extension from the VSCode marketplace.

2. Open the HTML file you want to work on.

3. Right-click anywhere in the HTML file and select "Open with Live Server" from the context menu.
