Additionally, provide alternative content for multimedia elements using HTML5 <video> and <audio> tags with fallback options for browsers that do not support them.

7. Test Responsiveness Across Devices

In addition to testing across different browsers, it’s crucial to ensure that your website is responsive and displays correctly on various devices, including desktops, laptops, tablets, and smartphones.
