I want to make a replica of the google homepage for a homework task, and I can't seem to format the two buttons (Google Search and I'm Feeling Lucky) below. My expected result:

I tried margins and other stuff but nothing seems to work. My code:
<!DOCTYPE html>
<html lang="en">
<head>
<title>Search</title>
<meta charset="utf-8">
<!-- This link tag is used to link html file with css file -->
<link rel="stylesheet" href="Styles/styles.css">
</head>
<body>
<div class="center">
<center>
<br>
<img src="https://www.google.com/images/branding/googlelogo/2x/googlelogo_color_272x92dp.png" alt="Google" width="272" height="92" class="Logo">
<br>
<br>
<form action="https://google.com/search">
<div class="box">
<input maxlength="2048" name="q" type="text" aria-autocomplete="both" aria-haspopup="false" autocapitalize="off" autocomplete="off" autocorrect="off" autofocus role="combobox" spellcheck="false" class="center input">
<input type="submit" value="Google Search" hidden>
</div>
<section>
<div>
<button type="submit" class="button">Google Search</button>
</div>
<div>
<button type="submit" class="button">I'm Feeling Lucky</button>
</div>
</section>
</form>
</center>
</div>
</body>

Sorry for asking such a stupid question, but I'm still learning this.
