.dropdown {
float:
left;

.topnav a.icon {
float: right;
display: block;
}
}
/* The "responsive" class is added to the topnav with JavaScript when the
user clicks on the icon. This class makes the topnav look good on small
screens (display the links vertically instead of horizontally) */
@media screen and (max-width: 600px) {
.topnav.responsive {position: relative;}
.topnav.responsive a.icon {
position: absolute;

top: 0;
}
