<HEAD>
  <LINK REL=STYLESHEET TYPE="text/css" HREF="mystyles.css"> [linked]
  <STYLE TYPE="text/css">
    @import url(standardstyles.css); [imported]
    H1, H2 { font: Arial,sans-serif; }
  </STYLE> [embedded]

<DIV STYLE="color: red">This block is red.</DIV> [inline style]

selectors { list of property:value pairs }
