中心底部切割的Bootstrop按钮

Question

我正在尝试在bootstrap中创建看起来像的按钮。

我在this链接中尝试了此代码，但它无效。这是我的代码。

HTML：

<div class="col-lg-12 col-md-12 col-sm-12 col-xs-12 cut" >               
    <div class="cut-bd cut-bd_red">
      <div class="cut-hd cut-hd_red">
            <button class="btn btn-primary btn-left-bar hdg">Home</button>
      </div>  
    </div>  
</div>

这是我的css代码：

    .cut {
  overflow: hidden;
  padding: 0 0 30px;
}

.cut-bd {
  padding: 15px 15px 0;
  position: relative;
}

.cut-hd {
  margin: 0 0 5px;
  padding: 0 0 5px;
}

.cut-hd_red { border-bottom: 1px solid darken(#e74c3c,5%); }
.cut-hd_green { border-bottom: 1px solid darken(#1abc9c,50%); }

.cut-bd_red {
  background: #e74c3c;
  color: #ecf0f1;
  text-shadow: 1px 1px rgba(#ffffff,.2);
  &:before {
    content: "";
    width: 100%;
    height: 30px;
    position: absolute;
    top: 100%;
    right: 30px;
    background: #e74c3c;
  }
  &:after {
    content: "";
    width: 0;
    height: 0;
    margin-left: -30px;
    position: absolute;
    top: 100%;
    left: 100%;
    border: 15px solid #e74c3c;
    border-right: 15px solid transparent;
    border-bottom: 15px solid transparent;
  }
}

.cut-bd_green {
  border-top: 5px solid #ecf0f1;
  background: #1abc9c;
  color: #ecf0f1;
  text-shadow: 1px 1px rgba(#ffffff,.2);
  &:before {
    content: "";
    width: 100%;
    height: 30px;
    position: absolute;
    top: 100%;
    right: 30px;
    background: #1abc9c;
  }
  &:after {
    content: "";
    width: 0;
    height: 0;
    margin-left: -30px;
    position: absolute;
    top: 100%;
    left: 100%;
    border: 15px solid #1abc9c;
    border-right: 15px solid transparent;
    border-bottom: 15px solid transparent;
  }
}

.intro {
  color: #ecf0f1;
  font-size: 3em;
  font-weight: bold;
  text-align: center;
  text-transform: uppercase;
  letter-spacing: 2px;
  text-shadow: 3px 3px rgba(darken(#2c3e50,5%),1);
}

.hdg {
  color: #ffff;
  font-size: 20px;
  font-weight: bold;
  text-transform: uppercase;
}

请提供任何参考或提示。

Bootstrap CSS覆盖了一些用于削减边缘的CSS。我是否还需要在按钮上应用此功能？
