Tell us what’s happening:

Hello everyone,

I am aware that you cannot combine css and html together on the same line of code but I’m having trouble trying to understand what I am reading here.

Could someone help me out?

Your code so far

<!-- file: index.html -->
<!DOCTYPE html>
<html lang="en">    
  <head>
    <meta charset="UTF-8">
    <title>City Skyline</title>
    <link href="styles.css" rel="stylesheet" />
  </head>

  <body>

<!-- User Editable Region -->

   <div class="background-buildings"><div class="bb1"></div></div>

   

<!-- User Editable Region -->

  </body>
</html>
/* file: styles.css */
* {
  border: 1px solid black;
  box-sizing: border-box;
}

body {
  height: 100vh;
  margin: 0;
  overflow: hidden;
}

.background-buildings {
  width: 100%;
  height: 100%;
}

give .bb1 a width of 10% and height of 70%.

I get that. I understood the numbers and the selector, it was just a matter of where to put that.
