利用table实现页面实现移动端页面自适应表单_html/css_WEB-ITnose

为了实现如图所示的效果：

设置table的宽度为百分比的值，让其宽度随页面的宽度而改变。input占据整个td的宽度。
主要html代码如下：

<form action="">    <table class="form">        <tr>            <td colspan="3"><input type="text" placeholder="姓名" name="username" id="user"/><span></span></td>        </tr>        <tr>            <td colspan="3"><input type="text" placeholder="公司名称" name="company" id="company"/><span></span></td>        </tr>        <tr>            <td colspan="3"><input type="text" placeholder="国家/地区" name="area" id="area"/><span></span></td>        </tr>        <tr>            <td colspan="3"><input type="phone" placeholder="手机" name="phone" id="phone"/><span></span></td>        </tr>        <tr>            <td colspan="3"><input type="email" placeholder="电子邮箱" name="email" id="email"/><span></span></td>        </tr>        <tr>            <td colspan="3"><input type="text" placeholder="确认邮箱" name="email-c" id="email-c"/><span></span></td>        </tr>        <tr>            <td class="r-box pl8" width="37%">是否开具发票</td><td class="r-box" width="21.9%"><label for="bill_y" class="r-label checked"><input type="radio" name="bill" id="bill_y"/>是</label></td><td class="r-box"><label for="bill_n" class="r-label"><input type="radio" name="bill" id="bill_n"/>否</label></td></td>        </tr>        <tr>            <td colspan="3"><input type="text" placeholder="抬头"/><span></span></td>        </tr>        <tr>            <td colspan="3" class="pb6"><input type="text" placeholder="联系地址"/><span></span></td>        </tr>        <tr>            <td colspan="3"><input type="submit" value="继续"/></td>        </tr>    </table></form>

主要的scss样式如下：

.form{  width: 96%;  margin: 0.3rem auto;  font-size: 0.7rem;  td{    height: 2.5rem;  }  input{    font-family: "Microsoft Yahei";    outline: none;    color: #d8d8d8;  }  input[type=text],input[type=phone],input[type=email]{    border: 1px solid #e10000;    height: 1.55rem;    line-height: 1.55rem;    padding-left: 0.4rem;    width: 100%;    box-sizing: border-box;    background: transparent;  }
