I have no idea what to do

Its asking me to do this "Currently, the width of the div with the class main is set to 400px, but the padding applied is adding an extra 40 pixels to its total width. Add a property that forces the padding into the width of the div." I don't know what to do

index.html 
<!DOCTYPE html>
<html>
<head>
    <title>Width, Height and Overflow Properties</title>
    <link rel="stylesheet" href="page.css">
    <link rel="stylesheet" href="style.css">
</head>
<body>   
    <nav>
        <a href="#">About Me</a>
        <a href="#">My Work</a>
        <a href="#">Contact Me</a>
    </nav>
    <div class="main">
        <p>Veggies sunt bona vobis, proinde vos postulo esse magis kohlrabi courgette sorrel rock melon summer purslane soybean bitterleaf fennel.</p>
        <p>Pumpkin ricebean gourd cauliflower water chestnut garlic parsley bunya nuts earthnut pea tomato lettuce. Swiss chard chickpea burdock soybean soko cucumber garlic wakame pea arugula azuki bean turnip greens spinach eggplant.</p>
        <p>Arugula cress bitterleaf rutabaga potato burdock celery chard eggplant desert raisin.</p>
    </div>
</body>
</html>
style.css 
nav a { 
  display: inline-block;
  width: 100px;
}

You're probably looking for the box-sizing property with the value border-box.
This forces the padding and borders to be calculated in any sizes you define; margins are still 'outside'.

.main {
    ---
}

nav a { 
  display: inline-block;
  width: 100px;
  padding: auto;
}

the extra padding is too much. so putting it at auto will keep it from adding extra width to the div.
