Bootstrap 3:Div不像以前那样工作

Question

我有section divs自己的形式.每个部分可以有多个字段.它适用于Bootstrap 2.3 css.当我用Bootstrap 3.0 css替换它时,所有字段都来自div部分.我试过检查元素,但找不到任何区别.
CSS

.section {
    position: relative;
    margin: 15px 0;
    padding: 39px 19px 14px;
    background-color: #fff;
    border: 1px solid #649300;
    -webkit-border-radius: 4px;
    -moz-border-radius: 4px;
    border-radius: 4px;

}

HTML

<div class="section" name="amount">
        <span class="section-title">Amount Information</span>
          <div class="span6 form-inline">
                <label class="pocLabel">

                Amount Of</label>
                <input type="text" name="amount" required="">
          </div>
          <div class="span6 form-inline">
                <label class="pocLabel">
                Customer First Name</label>
                <input type="text" name="firstName" required="">

                <input type="text" name="city">
          </div>
          <div class="span6 form-inline">
                <label class="pocLabel">
                State</label>
                <input type="text" name="state">

                State 2</label>
                <input type="text" name="state">
          </div>

      </div>

Bootstrap 3已经废弃了这些spanX类.用col-lg-X类替换它们.

请参阅此迁移指南,从v2.x到Bootstrap的v3.
