Learn Accessibility by Building a Quiz - Step 4

Tell us what’s happening:
I don’t understand, I can’t validate this step. I had a problem with the previous one too, I had to click the button many times.

He tells me : “Hint : You should add a new meta element to the head.”

I have the impression that the validation does not work.

   **Your code so far**
/* file: index.html */
<!DOCTYPE html>
<html lang="en">
 <head>
   <meta charset="UTF-8" />
   <meta name="viewport" content="width=device-width, initial-scale=1.0" />
   <meta name="description" content="freeCodeCamp Accessibility Quiz practice project" />
   <link rel="stylesheet" href="styles.css" />
 </head>
 <body>

 </body>
</html>

/* file: styles.css */
body {
	background: #f5f6f7;
	color: #1b1b32;
	font-family: Helvetica;
	margin: 0;
}
