CSS CSS Basics (2014) Basic Selectors ID and Class Selectors

Next, target the class main-heading. Give the heading a font-size property and set the value to 72 px.

Thought this looked right.

Did you place classes and id's correctly? It's very important. CSS needs to refer to something. There supposed to be a class="main-header" in <h1> element. <h1 class="main-header">

.main-header {
  background-color: orange;
}

.main-heading {
  font-size: 72px;
}

#main-content {
  background-color: lightsteelblue;
}

Try 72px instead of 32px. Should work.
