Styling native elements

Native HTML controls are a challenge to style. You can style any element in the web platform that uses Shadow DOM with a pseudo element ::pseudo-element or the /deep/ path selector.

video::webkit-media-controls-timeline {
  background-color: lime;
}

video /deep/ input[type=range] {

// Window (Internet Explorer 6 - 7, Opera 11.6, Safari 4 - 5)
(this.Window = this.constructor = function Window() {}).prototype = this;

// Window.chrome (Chrome 14-18, Safari 5.1)
this.Window = this.constructor;



// HTMLDocument (Internet Explorer 6 - 7)
(this.HTMLDocument = this.Document = this.document.constructor = function HTMLDocument() {}).prototype = this.document;

List of features that are supported by Opera 12 but not by Opera 15 due to the switch to Blink/Chromium:

• xhr.responseType = 'json' fixed as of August 19, 2013
• Link HTTP header
• Link HTTP header for stylesheets specifically
• Pressing Enter when an element with tabindex has focus should trigger a click
• Fragment identifiers in data: URIs should be handled correctly
• CSS gradients with transparency
• Accurate SVG rendering
• [`` where foo.svg is an SVG file that contains text looks terrible](https://code.google.com/p/chromium/issues/detail?id=33
