Cascading divs with triangle bottom borders

This is a follow-up to his question: Center triangle at bottom of div full width responsively

Again I'm stuck with my CSS for a project involving divs with triangle borders at the bottom:

I want a row of cascading divs to look like this (lower tringle colored red for demonstration purposes):

enter image description here

My code now looks like this:

html, body {
    padding: 0; margin: 0;
    color: white;
}
.top {
    background-color: #282C34;
    height: 500px;
    width: 100%;
    position: relative;
}
.bottom {
    background-color: #3B3E48;
    height: 500px;
    width: 100%;
}
.triangle {
    border-left: 50vw solid transparent;
    border-right: 50vw solid transparent;
    width: 0;
    height: 0;
    bottom: -40px;
    content: "";
    display: block;
    position: absolute;
    overflow: hidden;
    left:0;right:0;
    margin:auto;
}
.upperTriangle {
    border-top: 40px solid #282C34;
}
.lowerTriangle {
    border-top: 40px solid red;
}
<div class="top">
    <div class="triangle upperTriangle"></div>
</div>
<div class="bottom">
    <div class="triangle lowerTriangle"></div>
</div>
<div class="top">
    <div class="triangle"></div>
</div>

My problems:

Thanks a lot in advance for the help.

By adding position:relative; to your .bottom class and adding z-index:100; to your .triangle class I was able to get your triangles to appear the way you want them to.

See my fiddle: http://jsfiddle.net/rndwz681/1/

z-index sets the "layer" that an object appears on (higher number = closer to the user). It can only be applied to 'positioned' elements, but your absolute-positioned triangles qualify.
