Also, don't forget to include semicolon at the end of your statements :), so your statements

.content {
 transition-property: color, background
 transition-duration: 0.004s, 0.005s

should be

.content {
 transition-property: color, background;
 transition-duration: 0.004s, 0.005s;


no it should be 0.004s, 0.004s
