Question

各位大神 初学者 问的问题比较低级 请见谅.

还有bootstrap有没有可以再次利用的标签例如 margin-top 我直接可以引用的.

    <div class="container-fluid">
          <div class="row-fluid row nav_top">
            <div class="col-md-2 ">
                <a class="navbar-brand" href="#">Project name</a>
            </div>
            <div class="col-md-7 ">124</div>
            <div class="col-md-1 ">
              <button type="button" class="btn btn-default btn-sm">注册</button>
              <button type="button" class="btn btn-default btn-sm">登录</button></div>
            <div class="col-md-2 ">124</div></div>
          <div class="row-fluid row">
            <div class="col-md-2 ">
                
            <!-- 导航区 -->
              <ul class="nav nav-tabs row mt01" role="tablist">
                <li role="presentation" class="active"><a href="#home" role="tab" data-toggle="tab">图片列表</a></li>
