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; }
