Pseudo selectors

Hello everyone. Who can explain this to me???

You can use the :not(:last-of-type) pseudo-class to select all but the last element.

   **Your code so far**
/* file: index.html */
<!DOCTYPE html>
<html>
 <head>
   <title>Registration Form</title>
	  <link rel="stylesheet" href="styles.css" />
 </head>
 <body>
   <h1>Registration Form</h1>
   <p>Please fill out this form with the required information</p>
   <form action='https://register-demo.freecodecamp.org'>
     <fieldset>
       <label>Enter Your First Name: 
         <input></input>
       </label>
       <label>Enter Your Last Name:<input>
       </label>
       <label>Enter Your Email:<input>
       </label>
       <label>Create a New Password:<input>
       </label>
     </fieldset>
     <fieldset></fieldset>
     <fieldset></fieldset>
   </form>
 </body>
</html>
/* file: styles.css */
body {
 width: 100%;
 height: 100vh;
 margin: 0;
 background-color: #1b1b32;
	color: #f5f6f7;
}

label {
	display: block;
	margin: 0.5rem 0;
}

Challenge: Step 15

Link to the challenge:

MDN :not()

MDN :last-of_type

Basically this is saying “give me all the elements that are NOT the last of its type”. So for this step you want all the fieldsets that are NOT the last fieldset on the page.

Thanks, I’m grateful.
