标签： html css twitter-bootstrap-3

我有一些麻烦，当它崩溃时为所有页脚添加背景颜色，页脚中间有一些空格...我尝试过这个CSS代码{background-size：100％100％; } 

{
  height: 317px;
  background-color: #3b3b3b;
  margin-top: 200px;
  padding: 4% 0;
}
.no a {
  color: white;
}
footer .container {
  height: 317px;
  background-color: #3b3b3b;
  margin-top: 200px;
  width: 1500px;
}
footer ul,
.taber {
  margin-top: 100px;
}
.last,
.no {
  margin-top: 100px;
}
.last img {
  margin-bottom: 34px;
}
footer ul {
  margin: 0;
  padding: 0 0 0;
}
footer ul li,
.taber {
  font-size: 16px;
  font-family: Aleo;
  color: white;
  list-style: none;
  margin-bottom: 10px;
  font-size: 16px
}
@media (max-width: 723px) {
  .taber {
    border-bottom: 1px solid #ccc;
    padding-bottom: 10px;
    cursor: auto;
    color: yellow;
    background-color: #3b3b3b;
    background-size: 100% 100%;
  }
  .taber.collapsed:after {
    content: "+";
    float: right;
    font-size: 22px;
    margin-right: 10px;
  }
  .taber:after {
    content: "-";
    float: right;
    font-size: 22px;
    margin-right: 10px;
  }
  .panel-collapse {
    padding-left: 15px;
    padding-right: 15px;
  }
  #collapseOne,
  #collapsetwo,
  #collapsethree,
  #collapsefour {
    background-color: #3b3b3b;
  }
  footer >.container {
    padding-left: 0;
    padding-right: 0px;

看起来您可能正在处理collapsing-margin

使用以下规则（其中一种方式）对代码进行测试： 

  /* hold margins within containers */    
 .row>*>* {border:1px transparent solid;}

更新了代码段以运行：

@media (max-width: 723px) {
  .taber {
    border-bottom: 1px solid #ccc;
    padding-bottom: 10px;
    cursor: auto;
    color: yellow;
    background-color: #3b3b3b;
    background-size: 100% 100%;
  }
  .taber.collapsed:after {
    content: "+";
    float: right;
    font-size: 22px;
    margin-right: 10px;
  }
  .taber:after {
    content: "-";
    float: right;
    font-size: 22px;
    margin-right: 10px;
  }
  .panel-collapse {
    padding-left: 15px;
    padding-right: 15px;
  }
  #collapseOne,
  #collapsetwo,
  #collapsethree,
  #collapsefour {
    background-color: #3b3b3b;
  }
  
  /* hold margins within containers */
 .row>*>* {border:1px transparent solid;}
 .last img {display:block}/* just to erase the gap it produces here */
