Aligning css arrow boxes

问题:

My question is similar to this question: Arrow Box with CSS But instead of only 1 box I need to align several boxes. And still be able to see the arrow on all boxes.

In this example: http://jsfiddle.net/casperskovgaard/LHHzt/1/ I have created two arrow boxes that float to the left. The problem is that the arrow on the first box is not visible.

How do I make the arrow visible?

HTML:

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

CSS:

.arrow {
    float: left;
    width: 128px;
    height: 100px;
    background-color: #f0f0f0;
    border: 1px solid #999;
    position: relative;
}
.arrow:after {
    content: '';
    position: absolute;
    top: 0px;
    left: 128px;
    width: 0;
    height: 0;
    border: 50px solid transparent;
    border-left: 12px solid #f0f0f0;
}
.arrow:before {
    content: '';
    position: absolute;
    top: 0px;
    left: 129px;
    width: 0;
    height: 0;
    border: 50px solid transparent;
    border-left: 12px solid #999;
}

EDIT:

The first arrow must overlap the box to the right. See solution from artSx: http://jsfiddle.net/LHHzt/6/ Only thing missing from this solution is that it should be possible to add several (more than two) boxes

回答1:

if you change the z-index of the after psudeo element to 2 and then the before element to 1 then it should work as you intend:

.arrow {
    float: left;
    width: 128px;
    height: 100px;
    background-color: #f0f0f0;
    border: 1px solid #999;
    position: relative;
    margin-right:15px;
}
.arrow:after {
    content: '';
    position: absolute;
    top: 0px;
    left: 128px;
    width: 0;
    height: 0;
    border: 50px solid transparent;
    border-left: 12px solid #f0f0f0;
}
.arrow:before {
    content: '';
    position: absolute;
    top: 0px;
    left: 129px;
    width: 0;
    height: 0;
    border: 50px solid transparent;
    border-left: 12px solid #999;
}

add this :

.arrow:first-child{
 z-index:10;   
}

JsFiddle with correction

Just add a z-indexto your .arrow:before. Here is the live version http://jsfiddle.net/LHHzt/13/

.arrow:before {
    content: '';
    position: absolute;
    top: 0px;
    left: 129px;
    width: 0;
    height: 0;
    z-index:2;
    border: 50px solid transparent;
    border-left: 12px solid #999;
}

Works with as many box as you want :)

回答5:

Just add a margin to the arrow...

.arrow {
    float: left;
    width: 128px;
    height: 100px;
    background-color: #f0f0f0;
    border: 1px solid #999;
    position: relative;
    margin-right: 15px;
}

Or change z-index to display above if you want them to overlay

Just adding a margin to the arrow resolves the problem.

See this JSFiddle : http://jsfiddle.net/LHHzt/9/

I just added a

margin-right: 15px;
