The given CSS code defines a class named .vertical-line. Here's what it does:

1. display: block;

   • This makes the element behave like a block-level element (taking up the full width possible in its container and starting on a new line).

2. background: #cd9f82;

   • This sets the background color of the element to a shade of light brown (#cd9f82 is a hexadecimal color code).

3. width: 1px;

   • This sets the width of the element to 1 pixel, making it a very thin vertical shape.

4. height: 300px;

   • This sets the height of the element to 300 pixels, making it a tall shape.

Functionality:

When applied to an HTML element, this class creates a vertical line with a light brown color that is 1 pixel wide and 300 pixels tall. It is commonly used for styling or separating sections in a webpage, but note that the code snippet is incomplete because there's a missing semicolon after the background property, making it invalid as written. If corrected, it would work as intended.
