Usability is crucial for ensuring that a website is easy to navigate and interact with. It enhances user satisfaction by making web features accessible and intuitive, ultimately improving the overall user experience.

Responsive design ensures that a website adapts smoothly to various devices and screen sizes, offering a seamless user experience regardless of how the site is accessed. This is achieved using flexible layouts and media queries.

Web accessibility ensures that websites can be used by people with diverse abilities, following guidelines that make content more accessible to users with disabilities. This inclusivity enhances user engagement and expands the audience reach.

Visual hierarchy controls the arrangement and presentation of design elements, guiding users’ attention and facilitating comprehension. Effective hierarchy emphasizes important information and helps users navigate the site more efficiently.
