The challenge wants it to start suddenly, then ease out. Try using ease-out instead of ease-in

try the following answer:

.icon { transition-property: opacity; transition-duration: .5s; transition-delay: .3s; transition-timing-function: ease-out; }

Hi,

You need to add 'ease-out' at the end of your transition property.

Please see more info about easing effects

transition: <property> <duration> <timing-function> <delay>;

which would be:

transition: flex-grow .5s (add your ease-out function) and no need for a delay
