JS, CSS and HTML to implement the registration page

A registration page template implemented with HTML and CSS. Without further ado, here’s the code!

Update: Use JavaScript to implement username and password form validation.

The code is as follows:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Registration Page</title>
    <style>
        *{
            margin: 0px;
            padding: 0px;
            box-sizing: border-box;
        }
        body{
            background: url("img/register_bg.png") no-repeat center;
            padding-top: 25px;
        }

        .rg_layout{
            width: 900px;
            height: 500px;
            border: 8px solid #EEEEEE;
            background-color: white;
            /* Center the div horizontally */
            margin: auto;
        }

        .rg_left{
            /*border: 1px solid red;*/
            float: left;
            margin: 15px;
        }
        .rg_left > p:first-child{
