A German language e-commerce site selling car parts.
The site makes heavy use of custom
data attributes throughout, and also new
form elements and attributes. The rarely seen
pattern attribute is used in the part selector form on the home page (the two
inputs labelled HSN and TSN) to create a regular expression that the form field is validated against. It’s a very simple pattern in this case, and is made redundant by the
maxlength attribute, but nonetheless interesting to see in the wild.
The general structure of the site is perhaps not as noteworthy as there are a lot of untitled sections in the document outline.
