WHAT BROWSERS WORK?! - http://caniuse.com/
Source               - https://github.com/MichaelBaker/Getting-Happy-with-CSS
Selector tester      - http://dl.dropbox.com/u/8925091/Sandbox/Sandbox.html


-- HTML --
Why should we care about semantics?
  Accessibility mostly
  Different formats for viewing documents
You can make up your own tags!(sort of)


-- CSS --
What is CSS?: A presentation language designed to format HTML.
  Modern convention for web development: HTML for structure, CSS for design, Javascript for behavior.


Basic syntax:
/* Comment */
selector {
  property1:value1;
  property2:value2;
  property3:value3;
}

Three ways to include CSS
  inline
  <span style = "background: red" />

  embedded
  <head>
    <style type="text/css">
      span {
        background: red;
      }
    </style>
  </head>

  external
  <link rel = "stylesheet" href = "sheet.css" />


-- Selectors --
Selectors are patterns that will attempt to match nodes in the DOM

Tag selectors
  p
  li
  wicked
Comma separated selectors
  p, h1
. matches classes
  .important
# matches ids
  #awesome
. and # can be used in isolation or with tags
  span.important
Universal selector: *
  *
Descendent selectors: space
  p *
Attribute selectors: tag[attr="value"]
  li[name]
Child selectors: >
  ul > li
Adjacent sibling selectors: +
  span + strong
Pseudo-classes
  span:hover
Pseudo-elements
  span:first


-- Properties --
Property shorthand
inheritance
The cascade:   Importance, Specificity, Order
border: 1px solid black
  border-top-width: 1px;
  border-bottom-width: 1px;
  border-left-width: 1px;
  border-right-width: 1px;
  border-style: solid;
  border-color: black;
box model: padding, margin, border
           http://css-tricks.com/the-css-box-model/
margin: auto used for centering horizontally


-- Positioning --
Static
  Nothing to show, feh
Fixed
  Four corners position1
Relative
  Box stair step
Absolute
  Four corners boxes again
positioning-context!


-- Display --
block
  like paragraphs
inline
  like text
inline-block
  like text with children


-- Less important stuff --
Hugh Laurie
Importance: !important
@import
@font-face
@media
animation
