How can i make fancy corners in my website

I want to make corner like in this image

I am a beginner to frontend development. I tried this but i'm stuck now.

The Code:

* {
  margin: 0;
  padding: 0;
}

body {
  height: 100vh;
  display: flex;
  justify-content: center;
  align-items: center;
}

.container {
  background-color: white;
  border-radius: 15px
}

.box {
  text-align: center;
  font-size: 50pt;
}

#top {
  background-color: blue;
  position: relative;
  border-bottom-left-radius: 50px
}

#top:after {
  content: "";
  position: absolute;
  right: 0;
  top: 100%;
  height: 100px;
  width: 100px;
  border-top-right-radius: 50%;
  box-shadow: 0 -50px 0 0 black;
}

#bottom {
  background-color: red;
  position: relative;
}
<div class="container">
  <div class="box" id="top">Top</div>
  <div class="box" id="bottom">Bottom</div>
</div>

This HTML and CSS code defines a webpage with a centered container containing two boxes, one with a blue background ("Top") and a decorative shadow, and the other with a red background ("Bottom"). The styling includes rounded corners and a centered text.

Solution

  • I would just add additional containers around the top and bottom ones to set the opposite background-color

    * {
  margin: 0;
  padding: 0;
}

body {
  height: 100vh;
  display: flex;
  justify-content: center;
  align-items: center;
}

.container {
  background-color: white;
  border-radius: 15px
}

.box {
  text-align: center;
  font-size: 50pt;
}

#OuterTop {
  background-color: red;
}

#OuterBottom {
  background-color: blue;
}

#top {
  background-color: blue;
  position: relative;
  border-bottom-left-radius: 50px;
}

#bottom {
  background-color: red;
  border-top-right-radius: 50px;
  position: relative;
}
    <div class="container">
  <div id="OuterTop">
    <div class="box" id="top">Top</div>
   </div>
  <div id="OuterBottom">
    <div class="box" id="bottom">Bottom</div>
  </div>
</div>
