Focus on using HTML5 semantic tags like <main> to properly structure your page content. This enhances the readability and accessibility of your HTML.
For responsiveness, use relative units (em, %) in your CSS instead of fixed units (px). This ensures that your website adjusts well to different screen sizes and devices, providing a better user experience.
Implementing these practices will make your code more semantically meaningful and responsive, improving both usability and accessibility of your website.
