CSS: Curving the Bottom Edge of a div Inward

Introduction

Transforming the bottom edge of a rectangular div into a subtle curve is a unique design element that can enhance the aesthetics of any webpage. In this article, we'll explore a powerful CSS technique that allows you to achieve this effect effortlessly.

CSS Solution

Utilizing CSS's border-radius property, you can gracefully round the corners of your div, but for this specific task, we'll employ a slightly different strategy.

`.curved {
margin: 0 auto;
height: 400px;
background: lightblue;
border-radius: 0 0 200px 200px;
}`

As you can see, the crucial element of this code snippet is the border-radius property. We set the first two radii to 0, effectively keeping the top and left corners sharp. However, the bottom-left and bottom-right corners are given a generous radius of 200px, creating the illusion of a curve flowing inwards.

Alternative Approach Using Gradients

For a more subtle effect, you can leverage radial-gradients:

`.container {
margin: 0 auto;
width: 500px;
height: 200px;
background: radial-gradient(110% 50% at bottom, transparent 50%, lightblue 51%);
}`

Here, we create a gradient that smoothly transitions from transparent to light blue at the bottom of the container, giving the impression of a curved edge.

Conclusion

Mastering these CSS techniques empowers you to create visually engaging and dynamic designs. By understanding the nuances of border-radius and radial-gradients, you can effortlessly curve the bottom side of any div, adding a touch of elegance to your web pages.
