How do you ensure that a web page is cross-browser compatible?

To ensure that a web page is cross-browser compatible, testing the page in multiple browsers and adhering to standardized HTML and CSS practices is essential. This approach allows developers to identify how the page renders across different environments, as various browsers can interpret code differently. By standardizing HTML and CSS, you leverage best practices that are widely supported, which enhances the likelihood that your page will display consistently, regardless of the user's browser choice.

Utilizing standardized coding also minimizes the risk of utilizing features that may only be supported in certain browsers. This creates a more inclusive experience, allowing users to access the content regardless of whether they are using Chrome, Firefox, Safari, or another browser. The testing phase is critical because it provides real-world feedback, enabling adjustments to be made to ensure functionality and aesthetics remain intact across devices.
