The goal of front end web development is to create an appealing, easy-to-use interface that makes the Internet accessible to everyone. That means front end developers who are building web pages for the best user experience also need to consider the unique requirements of people with disabilities or other kinds of impairments such as problems with coordination, vision, or hearing. Accessibility designing may include resizing buttons, adding audio options, or changing a website color or fonts for easier reading. Over half the global population uses the Internet, so designing sites and pages for accessibility is a vital part of a front end developer job.
