"My Portfolio" project - CSS- Step 2

Hello fellow learners,

I am currently working on "My Portfolio" project in CSS. I am stuck at Step 2. I am unable to go back to the project Videos to review where I am going wrong. Please send me the link to "My portfolio" project videos.

I think I have done everything right, even then I am getting an error saying use flex property to align items horizontally. this is the code that I have used inside the

<style>

* {

  margin: 0;

  padding: 0;

  box-sizing: border-box;

  font-family: Courier;

}



nav {

  display: flex;

  justify-content: flex-start;

  padding: 2%;

  background-color: #4535AA;

  color: white;

}



#nav-options {

  margin-left: auto;

}



#nav-options a {

  color: black;

  text-decoration: none;

  padding: 5px;

  background-color: #FFB643;

  border-radius: 5px;

}

</style>

Please get back to me, I will truly appreciate.
