Parts Of HTML / CSS Code not showing up on page

I’m trying to create a second background/box but it isn’t showing up on my page. The specific code:

The MAIN-PAGE Class HTML and CSS

 <div class="MAIN-PAGE"></div>



.MAIN-PAGE {
  position: fixed;
  height: 100px;
  width: 100px;
  color: red;

}
