Head JS

It's main advantage is its size, at only 2.3 kb.

Head JS can load scripts like images, use HTML5 and CSS3 safely, target CSS for different screens, paths, states and browsers and much more.

Because of how it was built to function, Head JS allows itself to be the only script called in a website's HEAD section.

Head JS is a concise solution to universal issues in Web development, covering problems that deal with dependency injection, script queues, responsive design, code mobile versions, feature detection and many other more.
