Question

I want to make this shape : there supposed to be 3 div shapes like this. I built already some shape, but I want to see how this shape will fit in my website

I already built this : codepan

css example for what i did :

.mainOuterDiv{

    height:300px;

    overflow:hidden;
    background:#FFF;
}
.middDiv{
    width:70%;
    height:75px;
    background-color: #0CF;
    margin:0px auto;
    position:relative;
    margin-top:50%;
}
.innerLeft{
    position: absolute;
    left: -60px;
    top: -20px;
    width: 60px;
    height: 100%;
    z-index: 1;
    transform: skew(180deg,215deg);
    background-color: #0CF;
}
.innerRight{
    position: absolute;
    right: -60px;
    top: -20px;
    width: 60px;
    height: 100%;
    z-index: 1;
    transform: skew(180deg,145deg);
    background-color: #0CF;
}
.textDiv{
    z-index:9999;
    width:100%;
    height:100%;
    position:absolute;

Answer 1

There is some example :

.container
{
  position:relative;
  width:400px; height:302px;
  overflow:hidden;
}
.mainDiv
{
  height:300px; width:300px;
  background-color:white;
  border:solid 1px black;
  position:absolute;
  left:0;right:0;margin:auto;
}
.middDiv
{
  height:55px; width:70%;
  background-color:lightblue;
  position:absolute;
  bottom:0;left:0;right:0;
  margin:auto;
  z-index:10;
}
.leftDiv, .rightDiv
{
  position:absolute;
  bottom:26px;
  width:30%;height:48px;
  background-color:blue;
  z-index:10;
}
.leftDiv 
{
  left:-13%;
  transform:rotate(30deg) skew(30deg);
}
.rightDiv
{
  right:-13%;
  transform:rotate(-30deg) skew(-30deg);
}
.leftBDiv, .rightBDiv
{
  position:absolute;
  width:13%; height:47px;
  bottom:59px;
  background-color:black;
  z-index:9;
}
.leftBDiv
{
  left:-12%;
  transform:rotate(-30deg) skew(-30deg);
}
.rightBDiv
{
  right:-12%;
  transform:rotate(30deg) skew(30deg);
}

<div class="container">
  <div class="mainDiv">
    <div class="middDiv"></div>
    <div class="leftDiv"></div>  
    <div class="rightDiv"></div>
    <div class="leftBDiv"></div>
    <div class="rightBDiv"></div>
  </div>
</div>

I use different colors for middle, left and right blocks so You can see it.

If You will use border for those divs, You have to change positions: left, right and bottom for all of them.

There is fiddle example, too.
