我想通过bootstrap画一个电视遥控器，但我遇到了一些问题。 背景颜色超过，我甚至不知道如何消除它们。 请帮我看一下代码，随时给我一些建议！

@media screen and (min-width: 1200px) {

我检查了你的代码。

首先根据引导程序，我们必须覆盖12列，然后只有所有元素都覆盖背景。

按照这个就行了。

<div class="row" style="background-color:black;">
   <div class="col-lg-offset-1 col-lg-10">
        <div class="">
             <!-- then you have to put here of each col-lg-4 -->
        </div>
   </div>
  <div class="col-lg-offset-1"></div>
</div>
