Use the CSS Transform Property skewY to Skew an Element Along the Y-Axis?

Tell us what’s happening:
element with ID Top is already skewY(-10);
i am not getting what to do?

Your code so far


<style>
  div { 
    width: 70%;
    height: 100px;
    margin: 50px auto;
  }
  #top {
    background-color: red;
    transform: skewY(-10);
  }
  #bottom {
    background-color: blue;
    transform: skewX(24deg);
  }
</style>

<div id="top"></div>
<div id="bottom"></div>
