One example is a site that I developed by order - cryptoscamalert.com. The site contains information about identified fraudsters in the world of cryptocurrency.
Many features are available right out of the box and are configured declaratively, through
data- * attributes for HTML elements. Example: form validator.
Almost ALL Metro 4 components can be declaratively configured via data- * attributes!
Metro 4 was originally designed so that people of different specializations could use it for rapid prototyping of work sites, for example, SEO specialists.
The use of Metro 4 is quite diverse, another example is the leading Ukrainian hosting provider Mirohost.net uses Metro 4 to implement its administrative panel.
Of course, you can implement using Metro 4 and the tiled interface. Special elements - tiles are part of Metro 4. Real example - Start screen.
