# Foundation 输入框尺寸 ![](https://box.kancloud.cn/2015-12-30_5683952f18bcd.png) 使用网格的列来设置输入框的大小,如 `.large-6`, `.medium-6`, 等。 更多网格系统知识,可以点击 [网格系统](foundation-grid-system.html) 教程。 ### 实例 ``` <form>   <div class="row">     <div class="large-10 medium-7 columns">       <label>large-10 medium-7 (100% on small)         <input type="text" placeholder="Name">       </label>     </div>   </div>   <div class="row">     <div class="small-5 columns">       <label>small-5         <input type="text" placeholder="Name">       </label>     </div>   </div>   <div class="row">     <div class="medium-3 columns">       <label>medium-3 (100% on small)         <input type="text" placeholder="Name">       </label>     </div>   </div> </form> ``` ## 相等大小列 以下演示了相等大小列的实例: ### 实例 ``` <form>   <div class="row">     <div class="medium-4 columns">       <label>medium-4 (100% on small, stacked)         <input type="text" placeholder="Name">       </label>     </div>     <div class="medium-4 columns">       <label>medium-4 (100% on small, stacked)         <input type="text" placeholder="Name">       </label>     </div>     <div class="medium-4 columns">       <label>medium-4 (100% on small, stacked)         <input type="text" placeholder="Name">       </label>     </div>   </div> </form> ``` ## 内联标签 如果你希望你的标签内容显示在左边(不是上边),可以将标签元素 label 放在输入框左边的不同的列上,并使用 `.inline` 类来设置垂直居中: ### 实例 ``` <form>   <div class="row">     <div class="small-8">       <div class="row">         <div class="small-3 columns">           <label for="name" class="inline right">Name</label>         </div>         <div class="small-9 columns">           <input type="text" id="name" placeholder="First Name..">         </div>       </div>     </div>   </div> </form> ``` ## 前置和后置标签 你可以在 `&lt;div class="row collapse"&gt;` 中添加前置和后置标签,元素为: `&lt;_element_ class="postfix"&gt;` 或 `&lt;_element_ class="prefix"&gt;`。可以使用网格系统来设置前置和后置标签的大小: ### 实例 ``` <form>   <div class="row">     <div class="large-6 columns">       <div class="row collapse prefix-radius">         <div class="small-3 columns">           <span class="prefix">Prefix</span>         </div>         <div class="small-9 columns">           <input type="text" placeholder="Value">         </div>       </div>     </div>     <div class="large-6 columns">       <div class="row collapse postfix-radius">         <div class="small-9 columns">           <input type="text" placeholder="Value">         </div>         <div class="small-3 columns">           <span class="postfix">Postfix</span>         </div>       </div>     </div>   </div> </form> ``` ### 前置和后置标签按钮 可以使用 `&lt;a&gt;` 元素添加 `.button` 类来设置前置和后置按钮: ### 实例 ``` <a href="#" class="postfix button">Go</a> ``` ### 前置和后置标签圆角按钮 ### 实例 ``` <form>   <div class="row">     <div class="large-6 columns">       <div class="row collapse prefix-radius">         <div class="small-3 columns">           <span class="prefix">Prefix</span>         </div>         <div class="small-9 columns">           <input type="text" placeholder="Value">         </div>       </div>     </div>     <div class="large-6 columns">       <div class="row collapse postfix-radius">         <div class="small-9 columns">           <input type="text" placeholder="Value">         </div>         <div class="small-3 columns">           <span class="postfix">Postfix</span>         </div>       </div>     </div>   </div>   <div class="row">     <div class="large-6 columns">       <div class="row collapse prefix-round">         <div class="small-3 columns">           <a href="#" class="button prefix">Go</a>         </div>         <div class="small-9 columns">           <input type="text" placeholder="Value">         </div>       </div>     </div>     <div class="large-6 columns">       <div class="row collapse postfix-round">         <div class="small-9 columns">           <input type="text" placeholder="Value">         </div>         <div class="small-3 columns">           <a href="#" class="button postfix">Go</a>         </div>       </div>     </div>   </div> </form> ```
