enter image description here

I tried alot of things to fix it but it didn’t work
I was expecting it to display the folowing:
HTML:

<!DOCTYPE html>
 <html>
    <link rel="stylesheet" href="style.css">
    <title>Login To HackerForums</title>
    <div> 
        <H1>Login</H1><br> 
        <label>Username <br>
            <input> <br>
         <label>Password <br>
             <input> <br>
              <button>submit</button>
             </div>

               </html>

CSS:

div{
    border-radius: 10px; 
    text-align: center; 
    position: absolute; 
    background-color: gray
}
*{
    text-align: center; 
    font-family: sans-serif;
} 
button{
    color: green; 
    background-color: green; 
    border-radius: 10px
}
