Add a body selector that uses $font-stack for font-family. Inside body, nest an a selector that uses $primary-color for color.

SASS

$primary-color: #3498db;
$font-stack: 'Helvetica, sans-serif';

// Add nested styles for body and a here

Need a hint?

Use nesting by placing the a selector inside the body block.

Add a hover effect for links

Inside the nested a selector, add a :hover selector that changes the color to darken($primary-color, 15%) using the SASS darken() function.

SASS

$primary-color: #3498db;
$font-stack: 'Helvetica, sans-serif';

body {
  font-family: $font-stack;
  a {
    color: $primary-color;
    // Add :hover style here
  }
}
