Technical Documentation Page - Build a Technical Documentation Page

I have tried multi @media query but none have worked for me

Your code so far
body {
display: flex;
flex-direction: row;
font-family: ‘Open Sans’;
color: #4d4e53;
line-height: 1.5;
background-color: white;
margin: 0;
padding: 0;
}
#main-doc {
width: 75%;
height: 100vh;
}
@media (max-width: 600px) {
body {
flex-direction: column;
}
#main-doc {
max-width: 100%;
}
#navbar {
width: 100%;
margin-bottom: 40px;
}
}
#navbar {
height: 100vh;
width: 25%;
}
.nav-link a {
text-decoration: none;
font-family: ‘Open Sans’;
color: #4d4e53;
line-height: 1.5;
}
#ul-navbar {
list-style-type: none;

}

have you linked the stylesheet? please show your html code if you are still stuck.

Welcome to our community!
Give us all the code that you have written up to now in order to get the whole picture.
At least, for this time, I can see that you have two of the same selectors with different values for the same property. Plus, you have one closing curly brace that doesn’t belong there.
