Suppose the following code is given:

<html>
 <head>
 </head>
 <body>
   <header>
     <h2 class="logo">Title</h2>
     <div class="hamburger-box"></div>
     <nav class="main-navigation">
       <ul class="flex-container">
         <li class="flex-item">Home</li>
         <li class="flex-item">About</li>
         <li class="flex-item">Contact</li>
       </ul>
     </nav>
   </header>
 </body>
</html>

* {
    margin: 0;
    padding: 0;
    box-sizing: border-box;
}

header {
    display: flex;
    justify-content: space-between;
    margin: 20px;
    height: 30px;
}

.logo {
    height: 30px;
    flex-basis: 485px;
    flex-grow: 1;
    background-color: lightgreen;
}

.main-navigation {
    height: 30px;
    flex-basis: 243px;
    background-color: lightsteelblue;
    display: none;
}

    width: 30px;
    min-width: 30px;
    height: 30px;
    background-color: aqua;
}


@media screen and (min-width: 768px) {
    .flex-container {

        justify-content: space-evenly;
    }

    .hamburger-box {
        display: none;
    }

    .logo {
        flex-grow: 2;
    }

    .main-navigation {
        display: block;
        flex-grow: 1;

Remove the hamburger menu and only display the grey main menu.

Keep the `flex-grow` properties the same as before. 

When shrinking, make sure to shrink the title three times as fast as the menu to ensure there is sufficient space for the menu.

Apply a `min-width` to the whole header such that it does not fall apart when shrunk. For optimal results, feel free to change the `flex-basis` properties of the green and grey items.
