How to add a bottom curve in a div - CSS?

css, html

Solution

You can use `:after` pseudo element to create shape and add large `box-shadow` for blue background.

div {
  width: 300px;
  height: 150px;
  position: relative;
  overflow: hidden;
  text-align: center;
  color: white;
}
div:after {
  content: '';
  box-sizing: border-box;
  position: absolute;
  bottom: 0;
  left: 50%;
  height: 100px;
  width: 120%;
  border: 5px solid black;
  transform: translate(-50%, 50%);
  box-shadow: 0px 0px 0px 200px #00A2E8;
  border-radius: 50%;
  z-index: -1;
}

<div>Lorem ipsum</div>

Problem

Following is my code in which I am unable to create a bottom curve but increasing the border-top-left-radius/border-top-right-radius is not able to create a bump as shown in fig. Let me know how can I handle this using CSS only. Code: ``` .container { position: relative; } .rect { width: 334.5px; height: 223px; background: #34EFEE; text-align: center; line-height: 223px; } .rect:after { content: ''; position: absolute; bottom: 0px; width: 334.5px; height: 15px; background: #FFFFFF; left: 0; border-top-left-radius: 50%; border-top-right-radius: 50%; } ``` ``` <div class="container"> <div class="rect"> <h3>334.5 X 223</h3> </div> </div> ``` Expected Output - PLNKR -- http://plnkr.co/edit/7oTCHyn8PFABri0KHSrH?p=preview
