What am I missing? It won’t let me progress and my code looks exactly the same as the answer code.

  **Your code so far**

h1 {
  font-size: 68px;
h2 {
  font-size: 52px;
h3 {
  font-size: 40px;
h4 {
  font-size: 32px;
h5 {
  font-size: 21px;
h6 {
  font-size: 14px;

<h1>This is h1 text</h1>
<h2>This is h2 text</h2>
<h3>This is h3 text</h3>
<h4>This is h4 text</h4>
<h5>This is h5 text</h5>
<h6>This is h6 text</h6>

Your CSS worked for me maybe clear the cookie or try incognito mode.

What browser are you using?
Do you have any privacy extensions, like an Ad Blocker or Script Blocker?
Do you have an extension that changes the appearance of websites, like a dark mode or something that changes text?

Thanks! Clearing cache worked.
