Vendor prefixes
Vendor Prefixes

  • Some CSS rules won’t work without the vendor prefix.

    • Mozilla Browsers (Firefox) -moz

    • Webkit Browsers (Safari, Chrome) -webkit

    • Opera -o

    • Internet Explorer -ms

      <!--[if IE]> <![endif]-->

  • Not all CSS rules work with all browsers:

    • http://www.caniuse.com/

    • http://www.css3.info/selectors-test/

    • http://quirksmode.org/css/contents.html

New selectors

element1~element2Selects an element that is a general next sibling of another element.


[attribute^=value] Represents an element with the attribute whose value begins with the prefix value.

[attribute$=value] Represents an element with the attribute whose value ends with the prefix value.

[attribute*=value] Represents an element with the attribute whose value contains the prefix value.


New selectors!

New pseudo elements classes




Select elements that are first, last, or only child of its type of its parent






Selects an element that is the first, only, or last child of its parent.




New pseudo elements/classes!

More new pseudo elements classes
More new pseudo elements/classes!

  • nth-child(n)

  • :nth-of-type(n)

    • Allows you to select elements with a formula.

    • Example:


  • :nth-last-child(n)

  • :nth-last-of-type(n)

    • Work same as nth-child, except that they start counting at the last element instead of the first.

    • Example:


  • :root

    • Selects the root initial containing block (in HTML, this is the <html> tag)

    • Example:


  • :empty

    • Selects elements with no content (“empty”).

    • Example:


  • :target

    • Selects a targeted element – one with an ID with the same value as the URL's hash.

    • Example:



Still more new pseudo elements classes
Still more new pseudo elements/classes!

  • :enabled

  • :disabled

  • :checked

    • Allows a designer to apply style to enabled, disabled, or checked form field elements.

    • Example:


  • :not(selector)

    • Negates a selector.

    • Example:


  • ::selection

    • Defines style for text that a user selects.

    • Example:
