Ignoring mobile responsiveness 

Ignoring mobile responsiveness is another common mistake in web development. With most internet users accessing websites on their mobile devices, it is crucial to ensure that your website is responsive and can adapt to different screen sizes. Please do so to ensure a good user experience, with users needing help to navigate or read content on your website. To avoid this mistake, design your website with a mobile-first approach, use responsive design frameworks or CSS media queries, and test it on various devices to ensure it works correctly on all screen sizes.
