创建一个简单的登录表格

我试图创建一个简单的HTML登录,放在一个盒子里。我希望能有这样的东西。

我尝试了一些方法,但似乎都是徒劳的。以下是我到目前为止的代码。HTML。

<div id="login_form">
    <form name="f1" method="post" action="login.php" id="f1">
        <table>
            <tr>
                <td class="f1_label">User Name :</td><td><input type="text" name="username" value="" />
                </td>
            </tr>
            <tr>
                <td class="f1_label">Password  :</td><td><input type="password" name="password" value=""  />
                </td>
            </tr>
            <tr>
                <td>
                    <input type="submit" name="login" value="Log In" style="font-size:18px; " />
                </td>
            </tr>
        </table>
    </form>   
</div>

CSS。

#login_form {
    position: absolute;
    top: 20%;
    left: 30%;
    right: 30%;
    bottom: 20%;
    font-size: 18px;
}

#f1 {
    background-color: #ccc;
    border-style: solid;
    border-width: 1px;
}
.f1_label {
    white-space: nowrap;
}

我希望登录框位于浏览器的中心,所以我使用了#login_form。我有几个问题:使用fieldset标签是否是更好的方法?当我使用fieldset标签时,它产生了更多的问题;表单的外观和文本&amp的大小;密码字段的变化。

我知道<table>应该只用于表格数据,但以其他方式使用 label的任何其他方式似乎都会扰乱密码和用户名字段的大小/宽度(它还需要更多的样式设计)。

在表单中使用<table>是否是糟糕的编码实践?如果我使用<table>,未来的浏览器会不会错误地渲染页面?保持表单的nameid相同是个坏主意吗?我觉得保持它们相同不会产生任何问题(即使在同一个页面中使用jQuery)。

学习登录表格的良好开端。你是对的,fieldet可能不是最好的标签。

但是,我强烈建议你使用HTML5的强大的表单功能来编码它。

在创建表单方面,HTML5实际上比老的HTML更容易学习。

例如,请阅读以下内容。

<section class="loginform cf">  

        <ul>  
            <li>Email  
            <input type="email" name="usermail" placeholder="yourname@email.com" required></li>  
            <li>Password  
            <input type="password" name="password" placeholder="password" required></li>  
            <li>  
            <input type="submit" value="Login"></li>  
        </ul>  

</section>

这不是很容易理解吗?
