例子

h1{text-decoration:overline}
h2{text-decoration:line-through}
h3{text-decoration:underline}

this text has a line underneath it.
this text has a line over it.
this text has a line going through it.
this link will not be underlined,
    as links generally are by default. be careful when removing
    the text decoration on anchors since users often depend on
    the underline to denote hyperlinks.
this text has lines above and below it.

this text might blink for you,
    depending on the browser you use.
