Hey Raeed,

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

transition-timing-function: ease-out ease-in;

.nav-item { transition: flex-grow .5s ease-out; }

Timing-Function ease-out starts suddenly, then slows down at the end. The previous question asked you to write a transition shorthand, and it flowed into the the second question above.

Hey Kisha Fields Try the following answer

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

Work step-by-step to break down what they are asking for, do it long hand if you must:

.icon { right: -25px; transition-property: right; transition-duration: 0.4s; }
