div.zigzag > .container {    padding-bottom: 40px;    padding-top: 20px;  }  .zigzag {    position: relative;  }  .zigzag:before {    content: "";    display: block;    position: absolute;    top: -10px;    width: 100%;    height: 10px;  }  .zigzag:after {    content: "";    display: block;    position: absolute;    width: 100%;    height: 10px;  }  /* blue */    .blue {    background: #2c7892;    color: #fff;  }  .zigzag.blue:before {    background: linear-gradient(45deg, transparent 33.333%, #2c7892 33.333%, #2c7892 66.667%, transparent 66.667%), linear-gradient(-45deg, transparent 33.333%, #2c7892 33.333%, #2c7892 66.667%, transparent 66.667%);    background: -webkit-linear-gradient(45deg, transparent 33.333%, #2c7892 33.333%, #2c7892 66.667%, transparent 66.667%), -webkit-linear-gradient(-45deg, transparent 33.333%, #2c7892 33.333%, #2c7892 66.667%, transparent 66.667%);    background-size: 10px 20px;  }  .zigzag.blue:after {    background: linear-gradient(45deg, #2c7892 33.333%, transparent 33.333%, transparent 66.667%, #2c7892 66.667%), linear-gradient(-45deg, #2c7892 33.333%, transparent 33.333%, transparent 66.667%, #2c7892 66.667%);    background: -webkit-linear-gradient(45deg, #2c7892 33.333%, transparent 33.333%, transparent 66.667%, #2c7892 66.667%), -webkit-linear-gradient(-45deg, #2c7892 33.333%, transparent 33.333%, transparent 66.667%, #2c7892 66.667%);    background-size: 10px 20px;  }

<link href="//maxcdn.bootstrapcdn.com/bootstrap/3.3.4/css/bootstrap.min.css" rel="stylesheet"/>  <div class="row clearfix zigzag blue">    <div class="container">      <div class="col-md-12 column">        text here.      </div>    </div>  </div>

the problem caused display: table property inherited bootstraps clearfix pseudo element.

ensure display: block property applied making pseudo element more specific. simplest method append "div" before .zigzag:before , .zigag:after:

div.zigzag:before {   content: "";   display: block;   position: absolute;   top: -10px;   width: 100%;   height: 10px; } div.zigzag:after {   content: "";   display: block;   position: absolute;   width: 100%;   height: 10px; }
