Stuck at this task

It doesn't look like 'transition-duration: .4s;' is the answer. I don't know what else to try?? Please help

/* nav-item transitions ---------- */

.nav-item {
    flex-grow: 1;
  transition: flex-grow .5s;
  transition-timing-function: ease-out;

.nav-item:hover {
    flex-grow: 2;

/* nav icon transitions ---------- */

.icon {
  right: -25px;
  transition-duration: .4s;

.nav-item:hover .icon {
    right: 12%;

Hey Steffy Neptune,

You can use a shorthand property and include a transition property along with a duration:

  transition: right .4s;

If you would like to learn more about CSS transition, check out this website: https://www.w3schools.com/css/css3_transitions.asp

Hope this helps!

Hi Rabin,

I didn't realize that 'right' was a transition property that could be included in the shorthand without its value of -25px. However it worked! Thank you so much for your help.
