Smart Ways to View HTML Files in Visual Studio Code

HTML previewing is vital for web developers to ensure their designs and functionality align perfectly.

While VS Code is a popular choice for HTML editing, it doesn’t have built-in support for HTML preview. However, there are available HTML preview extensions in the VS Code Marketplace.

Thankfully, various extensions and tools make previewing HTML seamless, whether within the editor or in an external browser.

Let’s dive into the best methods to view HTML files in Visual Studio Code and optimize your development workflow.

Key Points:
