How to create uneven rounded sides on a div?

You can consider clip-path

.box {
  height: 200px;
  width: 200px;
  background: blue;
  clip-path: circle(75% at 65% 10%);
}

<div class="box">

</div>

Or use radial-gradient

.box {
  height: 200px;
  width: 200px;
  background: radial-gradient(circle at 65% 10%, blue 75%,#0000 75.5%);

}

<div class="box">

</div>

Or use a pseudo element with border-radius and rely on overflow

.box {
  height: 200px;
  width: 200px;
  position: relative;
  overflow: hidden;
}

.box:before {
  content: "";
  position: absolute;
  inset: 0 -10% 10%;
  background: blue;
  border-radius: 0 0 50% 100%;
}

<div class="box">

</div>

And let’s don’t forget the SVG solution (as a regular element or background)

svg {
 display:inline-block;
}

.box {
  display:inline-block;
  height:200px;
  width:200px;
  background:url("data:image/svg+xml;utf8,<svg xmlns="http://www.w3.org/2000/svg" viewBox='0 0 64 64'  width="200" height="200" fill="blue"> <path d='M0 0 L0 28 C10 46 30 60 64 48 L64 0 Z' /></svg>")0 0/100% 100% no-repeat;
}

<svg
  xmlns="http://www.w3.org/2000/svg"
  viewBox='0 0 64 64'
  width="200" height="200"
  fill="blue">
  <path d='M0 0 L0 28 C10 46 30 60 64 48 L64 0 Z' />
</svg>

<div class="box">
</div>

Here is a good online tool to easily adjust the SVG http://jxnblk.com/paths/?d=M0 0 L0 28 C10 46 30 60 64 48 L64 0 Z

You can also consider mask-image:

.box {
  height: 200px;
  width: 200px;
  background:blue;
  -webkit-mask-image: radial-gradient(circle at 65% 10%, #fff 75%,#0000 75.5%);
          mask-image: radial-gradient(circle at 65% 10%, #fff 75%,#0000 75.5%);

}

<div class="box">

</div>

Here is another syntax for the radial-gradient solution without the use of at which is not supported in Safari

.box {
  height: 200px;
  width: 200px;
  background: 
    radial-gradient(blue 60.5%,#0000 61%) 35% 100%/200% 200% no-repeat;
}

<div class="box">

</div>
