everyone. I got the design with uncommon shape as a background of block and have no idea how to realize it. I know, that technologies like canvas or webgl can help me to solve that problem. But I haven't studied these technologies well yet. So, here is what I'm trying to do(picture below)

And also part of my HTML code

<section class="page__requests">
<canvas id="canvas"></canvas>
<div class="requests__container">
    (content)
</div>

.page__requests{
    position: relative;
}
#canvas{
   position: absolute;
   top: 0;
   left: 0;
   width: 100%;
   height: 100%;
   background-color: #fff;
}
