Shadow DOM in HTML5
When developing UI using HTML and JavaScript, as it happens when using jQuery libraries (and similar), the internal implementation of the widgets we draw on screen is not encapsulated from the rest of the page. This lack of encapsulation means that whenever the page CSS or the page JavaScript change it might influence our UI. […]

The use strict; Statement in Perl
