body {
  background-color: #CCC;
}

Here, body is the selector for the HTML body element. background-color is a CSS property, and #CCC is a color value represented by a hexadecimal code. You can change the background color by changing the value of #CCC. You can also set the background color using the color's name or RGBA value.
