Hi, In this tutorial, I am going to explain, How to Design The DOT Menu.
.dot { position: absolute; width: 6; height: 6; visibility: hidden; background-color: red; font-size: 1px; cursor: pointer; cursor: hand; z-index: 100 }
.dotoff { position: absolute; width: 6; height: 6; visibility: hidden; background-color: gray; font-size: 1px; cursor:default; z-index: 100}
.dotempty { position: absolute; width: 6; height: 6; visibility: hidden; background-color: orange; font-size: 1px; cursor: pointer; cursor: hand; zindex: 100 }
.caption { position: absolute; visibility: hidden; font-family: Tahoma; color: black;
font-size: 11px; text-align: Center; cursor: default; z-index:
1 }
body { margin: 0px; background-color: white; }
a { color: silver; text-decoration: none }
p { font-size: 10px; font-family: tahoma; color: black }
