  background-color: yellow
.ie7 .example {
  background-color: orange

  background-color: gray
.win.gecko .example {
  background-color: red
.linux.gecko .example {
  background-color: pink
.opera .example {
  background-color: green
.konqueror .example {
  background-color: blue
.webkit .example {
  background-color: black
.example {
  width: 100px;
  height: 100px;
.no_js { display: block }
.has_js { display: none }
.js .no_js { display: none }
.js .has_js { display: block }
