Progressive enhancement

Progressive enhancement is a way to make websites that work for everyone. It helps to make sure that the website you visit works on whatever kind of device or browser you are using. It also helps make sure that everyone who visits the website, even those with disabilities, can use the website. To do this, the website creators first use the most basic web technologies, like basic HTML and CSS, to make sure the website works on all devices. Then they progressively add more and more features, like fancy Javascript and animations, as needed. That way, everyone can access the website, regardless of what device or browser they are using.
