Intro component with sign-up form

Hey Alex! Great job! The site looks great. I have tiny suggestions to polish it.

• Center the main container so the content sits nicely on the middle of the screen (in your case, maybe adding margin: 0 auto; on the <main>. Although as a better practice, I would suggest wrapping everything in a <div> and give it a container class.
• Your <input> should have <label>, that's why you're having html issues on your report. Also, consider wrapping your forms with a <form>, it's a better practice from the semantic point of view

An example would be:

<form>
  <label for="firstName">First name:</label>
  <input type="text" id="firstName" name="firstName" value="John">
  <label for="lastName">Last name:</label>
  <input type="text" id="lastName" name="lastName" value="Doe">
</form>

Just tiny things! Overall it's a great job! Keep at it!
