div在顶部和底部带有双箭头 [英] Div with double arrow on top and bottom

问题描述

我不是CSS方面的专家，因此要为我的div实现以下形状我会很努力:

I'm not an expert with CSS and I'm gonna be struggled in order to achieve the following shape for my div:

然后我想在中间插入文本.

And then I would like to insert text in the center.

如何获得此形状?

以下，我的一些尝试:

 <div class="triangle-down-white" style="height:400px;"> 
                    try
                </div>

和CSS

.triangle-down-white {
    width: 100%;
    height: 0;
    padding-left:50%;
    padding-top: 4%;
    overflow: hidden;
    background: rgba(140,  140,  140, 0.33);

}
.triangle-down-white:before, 
.triangle-down-white:after {
    content: "";
    display: block;
     height: 122px;
     width: 122px;

    margin-left:-1000px;

    border-left: 1000px solid transparent;
    border-right: 1000px solid transparent;
    border-top: 100px solid rgba(140,  140,  140, 0.33);

}



.triangle-down-white:before
{ /* hide arrow tails background */
      border-top: 100px solid white;
}

更新 我添加了新样式V形符号，但文本显示在div后面.我正在使用引导程序，并且html代码如下:

UPDATE I added the new style chevron but the text appear behind the div. I'm using bootstrap and the html code is the following:

<div class="row"> 
                <div class="col-sm-12" id="chevron">
                <p>asdasdasdasasdaasdsadasadsadsasd</p>
                </div>
            </div>

其余代码完全是引导程序的标准代码.

The rest of the code is completely the standard one for bootstrap.

已解决

我在新元素上添加了z-index:-1.

I added z-index: -1 at the new element.
