Evolution of the Web

Illustration of different devices connecting onto the internet. This includes desktop and laptop computers, mobile phones and tablets, televisions, camera, and game controllers. The illustration also represents different industry sectors such as mobile, gaming, digital publishing, healthcare, and many more sorrounding the 'Open Web Platform' in the center of the illustration.

Web Accessibility

At the bottom of the illustration are the core technical specifications of the Web, such as HTML, XML, CSS, SVG, SMIL, and others. On top of these technical specifications are the accessibility guidelines ATAG, WCAG, and UAAG. From the left, developers use authoring and evaluation tools to create content – ATAG is relevant in this context. From the right, users use browsers, media players, and assistive technologies to access the content – UAAG is relevant here. On the top-most center is the content, which includes text, images, forms, and more – WCAG is relevant in this context.
