Webmaster level: all
A common annoyance for web users is when websites require browser technologies that are not supported by their device. When users access such pages, they may see nothing but a blank space or miss out a large portion of the page's contents.

Developing modern multi-device websites
Fortunately, making websites that work on all modern devices is not that hard: websites can use HTML5 since it is universally supported, sometimes exclusively, by all devices. To help webmasters build websites that work on all types of devices regardless of the type of content they wish to serve, we recently announced two resources:
- Web Fundamentals: a curated source for modern best practices.
- Web Starter Kit: a starter framework supporting the Web Fundamentals best practices out of the box.
As always, if you need more help you can ask a question in our webmaster forum.
