Possible to have slanted stacked divs with one having a background image? - html

Question

Hello take a look at this picture of the comp I am trying to mimic through html and css.
The top div is a regular div with a white background.
The bottom div will have a background video.
The html structure is simple and will look something like this:
<div class="top-div">
<!-- stuff -->
</div>
<div class="bottom-div">
<video autoplay="" loop="">
<source src="myvideo.mp4" type="video/mp4">
<source src="myvideo.ogg" type="video/ogg">
</video>
</div>
CSS:
.top-div {
height: 500px;
width: 100%
}
.bottom-div {
height: 500px;
width: 100%;
position: relative;
}
.banner video {
position: absolute;
right: 0;
bottom: 0;
min-width: 100%;
min-height: 100%;
width: auto;
height: auto;
z-index: -1;
background: url() no-repeat;
background-size: cover;
filter: brightness(30%);
-webkit-filter: brightness(30%);
}
I know how to properly set up the video, but I am unsure how to go about making the slanted effect.
I was thinking I could use a psuedo element to create a triangle and place it on top of the div and have it z indexed over the video div, but that seems a little hacky.
Is there a best practice to do this? I didnt write this question for someone to give me full code. I just need someone to point me in the right direction and I can do it myself.
Thanks!

Easy and simple way is use CSS transform: skew. Add this inside your div where you want to be slanted then adjust the degrees.
transform: skew(0deg,-5deg);
Above skew style means (0deg(x), -5deg(y)) axis.
* {
-moz-box-sizing: border-box;
-webkit-box-sizing: border-box;
box-sizing: border-box;
}
body {
margin:0;
}
.headerimage {
background-color:#003a6f;
height:300px;
width:100%;
background-size:cover;
position:relative;
z-index:-1;
}
#backshape {
z-index:1;
display:block;
float:left;
margin-top:-100px;
width:100%;
background:white;
transform:skew(0deg,10deg);
-ms-transform:skew(0deg,10deg); /* IE 9 */
-webkit-transform: skew(0deg,-5deg);
}
.full-image {
width: 100%;
height: 200px;
}
.footer {
height: 100px;
background: rgb(253, 253, 253);
width: 100%;
margin-top: 425px;
z-index: 500;
position: relative;
}
<div class="headerimage">
</div>
<div id="backshape">
<img src="http://placehold.it/540x500" class="full-image">
</div>
<div class="footer">
</div>

I've put together a pen using skew as #adam suggested.

The HTML
<header class="header" id="header">
<div class="skew">
<div class="header-inner">
<h1 class="logo">White space</h1>
</div>
</div>
</header>
<div class="container">
<main class="main">
<div class="main-container">
<section>
<h1>Video</h1>
<p></p>
</section>
</div>
</main>
</div>
The CSS
html {
font-family: 'Roboto Condensed';
color: #fff;
background: #fafafa;
}
body {
padding: 0em 0em;
}
.header {
z-index: 1;
position: relative;
}
.header .skew:before {
content: '';
position: absolute;
left: 0;
bottom: 0;
overflow: visible;
width: 100%;
height: 250px;
background: #00bcd4;
z-index: -1;
-webkit-transform: skewY(-10deg);
-moz-transform: skewY(-10deg);
-ms-transform: skewY(-10deg);
-o-transform: skewY(-10deg);
transform: skewY(-10deg);
-webkit-backface-visibility: hidden;
backface-visibility: initial;
}
.header .skew .header-inner {
padding: 20px;
margin-left: auto;
margin-right: auto;
}
.logo {
margin: 0;
}
section
{
text-align:center;
color: white;
background-color: red;
height: 100vh;
width: 100%;
position: absolute;
top: 0;
}
section h1 {
text-align: center;
color: white;
padding-top: 150px;
}
skewY() skews an element along the Y-axis by the given angle.
transform: skewY(-10deg);
