Responsive Web Design

Status roadmap update: srcset, <main> element, and date inputs in development

For a long time the development team at MSDN have been hinting about the work towards work on the responsive image element and now it;s official. They have begun work on implementing the srcset attribute for image elements focussing initially on the x descriptor to provide higher resolution images
specifically for device DPI.

Thankfully they’re also going to include the sizes and <picture> element features in the future as well.
