Some examples we'll use to practice style declarations

BODY {background-color:beige}

also try line-height, letter-spacing (in em units)
H1 {font-family: verdana; font-size: 36pt; color:maroon}
H2 {font-family: verdana; font-size: 20pt; color: sienna}
H3 {font-family: verdana; font-size: 18pt; color:midnightblue}
{text-indent: 2em; font-family: arial; color: black}

also try background:yellow and watch what happens
LI {font-family: verdana; color:darkolivegreen}
A:link {color: green; font-weight: bolder; text-decoration: none}
A:visited color: red; text-decoration: none}
A:hover {color: orange; text-decoration: underline}
A:active {color: yellow; text-decoration: none
