css3 html5 Login page

Many websites now have registration pages and login pages, such as Taobao, JD.com, WeChat, etc., which require registration and login. So how do we use HTML5 and CSS3 to write these pages? Now I will teach you step by step how to write a login page using html and css3.

<form id="login">
    <h1 id="Log-nbsp-In">Log In</h1>
    <fieldset id="inputs">
        <input id="username" type="text" placeholder="Username" autofocus required>
        <input id="password" type="password" placeholder="Password" required>
    </fieldset>
    <fieldset id="actions">
        <input type="submit" id="submit" value="Log in">
        <a href="">Forgot your password?</a><a href="">Register</a>
    </fieldset>
</form>

Features of HTML 5 used:

placeholder – a short prompt for the input box, when the input box receives input When the focus is placed, the prompt message automatically disappears

required – Specifies whether the input element must provide

autofocus – Specifies whether the input box automatically obtains input focus after the page is loaded

type =”password” – Specify password input (not exclusive to HTML5)

CSS

Here we use some proprietary properties of CSS3, including:

Box-shadow Can help us make a very good border shadow

#login  
{  
    box-shadow:  
          0 0 2px rgba(0, 0, 0, 0.2),  
          0 1px 1px rgba(0, 0, 0, .2),  
          0 3px 0 #fff,  
          0 4px 0 rgba(0, 0, 0, .2),  
          0 6px 0 #fff,  
          0 7px 0 rgba(0, 0, 0, .2);  
}
Stitch effect (缝效果)
#login  
{  
    position: absolute;  
    z-index: 0;  
}  
 
#login:before  
{  
    content: &#39;&#39;;  
    position: absolute;  
    z-index: -1;  
    border: 1px dashed #ccc;  
    top: 5px;  
    bottom: 5px;  
    left: 5px;  
    right: 5px;  
    -moz-box-shadow: 0 0 0 1px #fff;  
    -webkit-box-shadow: 0 0 0 1px #fff;  
    box-shadow: 0 0 0 1px #fff;  
}

Subtle gradient lines

h1  
{  
    text-shadow: 0 1px 0 rgba(255, 255, 255, .7), 0px 2px 0 rgba(0, 0, 0, .5);  
    text-transform: uppercase;  
    text-align: center;  
    color: #666;  
    margin: 0 0 30px 0;  
    letter-spacing: 4px;  
    font: normal 26px/1 Verdana, Helvetica;  
    position: relative;  
}  
 
h1:after, h1:before  
{  
    background-color: #777;  
    content: "";  
    height: 1px;  
    position: absolute;  
    top: 15px;  
    width: 120px;  
}  
 
h1:after  
{  
    background-image: -webkit-gradient(linear, left top, right top, from(#777), to(#fff));  
    background-image: -webkit-linear-gradient(left, #777, #fff);  
    background-image: -moz-linear-gradient(left, #777, #fff);  
    background-image: -ms-linear-gradient(left, #777, #fff);  
    background-image: -o-linear-gradient(left, #777, #fff);  
    background-image: linear-gradient(left, #777, #fff);  
    right: 0;  
}

    background-image: -webkit-gradient(linear, right top, left top, from(#777), to(#fff));
