Why should you test web pages using multiple browsers during site development?

Testing web pages using multiple browsers during site development is essential to ensure proper rendering in all browsers. Each web browser interprets HTML, CSS, and JavaScript in slightly different ways, which can lead to variations in how a site appears and functions across them. By testing in multiple browsers, developers can identify inconsistencies or bugs that might affect user experience, such as layout shifts, styling discrepancies, and functionality issues related to specific features.

Ensuring proper rendering helps maintain a consistent user experience, as different users may prefer or only have access to particular browsers. By addressing these issues during development, a site can achieve its intended design and usability across the board, accommodating a broader audience and improving overall satisfaction. This approach also minimizes the need for costly adjustments after launch, making it a best practice in web development.
