Question

我修改了bootstrap导航栏，将崩溃断点从768px更改为992px。这是我使用过的解决方案：stackoverflow.com/questions/18192082/bootstrap-3-navbar-collapse

问题：在以下条件下搜索输入不是全宽

1）屏幕尺寸介于768px＆amp; 992px

2）崩溃被切换

我试过了width 100%＆amp;在stackoverflow上找到许多其他建议。这是一个demo on codepen

容器div是给出导航栏宽度的东西，所以如果删除它，它应该可以工作：

      <form class="navbar-form navbar-left">
        <div class="input-group">
          <input type="text" class="form-control" name="q" placeholder="Search Google">
          <span class="input-group-btn"><button type="submit" class="btn btn-primary">Search</button></span>

      </form>
    </ul>
  </div>
</div>

Answer 2

在样式表的底部添加此代码。在您的codepen上测试过。

@media (min-width: 768px) and (max-width: 991px) {
  .navbar-form .input-group .input-group-btn {
    width: 1%;
  }
}
