css shapes - Arrow before and after a box with CSS

Question

I'm trying to create in a single box, two arrows, one as a pointer and the other one into the box just behind.

Can not find the way to get the arrow right behind.

Someone can help me??

here i post the link with the sample: http://jsfiddle.net/7Esu2/

CSS:

.arrow {
    width:210px;
    height:40px;
    background-color:#CBCBCB;
    border: 1px solid #CBCBCB;
    position:relative;
    text-align:center;
    font-size:20px;
    font-weight:bold;
    line-height:40px;
}
.arrow:after {
    content:'';
    position:absolute;
    top:-1px;
    left:210px;
    width:0;
    height:0;
    border:21px solid transparent;
    border-left:15px solid #CBCBCB;
}
.arrow:before {
    content:'';
    position:absolute;
    top:-1px;
    left:211px;
    width:0;
    height:0;
    border:21px solid transparent;
    border-left:15px solid #CBCBCB;
}

HTML:

<div class="arrow">
    FLECHA
</div>

Answer 1

I prefer using inline-blocks over absolute positioning. Also, :before and :after create child elements (inside) the element you specify them on (at the beginning and end). For this, it would probably be best to have a wrapper (or inner) block, like so:

<div class="arrow">
    <div class="inner-arrow">
        FLECHA
    </div>
</div>

Then the inner block is going to get most of the styling, as the wrapper is primarily there to contain the :before and :after. The wrapper (.arrow) needs to have font-size: 0 (or some other method to make the white-space around the inner block, .inner-arrow, go away).

.arrow {
    font-size: 0;
}
.inner-arrow {
    width:210px;
    height:40px;
    display: inline-block;
    background-color:#CBCBCB;
    text-align:center;
    font-size:20px;
    font-weight:bold;
    line-height:40px;
    vertical-align: middle;
}

Most of the styles for .arrow:before and .arrow:after will be the same, so we'll group those. Then specify the differences below (they have to be below to override the common styles).

.arrow:before,
.arrow:after {
    content:'';
    display: inline-block;
    width:0;
    height:0;
    border:20px solid transparent;
    vertical-align: middle;
}
.arrow:before {
    border-top-color: #CBCBCB;
    border-bottom-color: #CBCBCB;
    border-right-color: #CBCBCB;
}
.arrow:after {
    border-left-color: #CBCBCB;
}

This is all in the a fiddle.
