Anything that can show websites can read and display HTML. Like it or not, HTML is the way we structure plain text for the web, because HTML is the single most portable and universally readable format at the time of this writing. There’s only one type of content that can be viewed on virtually any web-enabled device, and that is plain text, or rather, plain text that’s been structured with HTML. This is great, but there’s a problem: technically complex or advanced user interfaces can’t be viewed or used on every device. When embedding these types of apps within a web page, there may be a focus on making that interface accessible-ensuring that the user can navigate with nothing more than a keyboard, for example. It’s easy for developers to plot out company locations on a map. Take a geographical mapping application such as Open Street Maps or Google Maps as an example. One of the biggest problems in web accessibility is that many people start with the advanced user interface, take that as a given, and try to “add accessibility.” Many websites are designed from the UI in rather than from the content out. It can also benefit those with technological limitations, such as an old browser or slow internet connection. Web accessibility means that all people can access web content and services regardless of disability. No app simply contains buttons with nothing on them, text fields without labels, and absolutely no text on the page. This tends to be the case even if the site’s purpose is informational.īy the same token, I’ve never seen a web app without content. Most websites composed of documents are run by an application such as a content management system that requires a user interface. For our purposes, if it’s on the web, it’s probably both. We need not concern ourselves with the heated discussions about apps versus documents. Many developers advocate creating a distinction between web apps and web documents, referring to information-based websites, such as the W3C’s first web page-or your blog-as web documents. We have technologies like JavaScript and SVG that let us draw on the screen, or even create entire user interfaces. We’ve added to the basic building blocks of the web, which were essentially (structured) plain text, hyperlinks, and images. The world’s first website was essentially mobile ready.
