How Can I Create a Hexagon with Curved Top and Bottom Edges Using CSS?

Enhancing the Hexagon with Curved Top and Bottom Edges

To address the issue of creating a fully curved hexagon using CSS, let's delve into the code and understand how to modify it to achieve the desired effect:

.hex {
  position: relative;
  margin: 1em auto;
  width: 10em;
  height: 17.32em;
  border-radius: 1em / 0.5em;  <!-- Border radius modification -->
  background: orange;
  transition: opacity .5s;
}

The crucial change in this code is the modification of the border-radius property. Originally, the hexagon had a circular radius of 1em applied to both its width and height. By altering it to 1em / 0.5em, we are effectively creating an elliptical border radius. This elongated radius allows for the curvature of the top and bottom edges, while the width of the semi-circle remains constant.

Explanation:

To understand the significance of this adjustment, consider a circle and an ellipse. A circle has a uniform radius in all directions, while an ellipse has different radii along its different axes. By specifying the border-radius as '1em / 0.5em', we are defining an ellipse whose horizontal radius is 1em (the width of the hexagon), and its vertical radius is 0.5em (half the height of the hexagon). This results in the curved edges at the top and bottom of the hexagon.

Other CSS:

The additional CSS elements create two pseudo-elements, :before and :after, which are positioned absolutely inside the hexagon. They inherit the width, height, border-radius, and background of the hexagon, creating two overlapping hexagons rotated by 60 degrees in opposite directions. These rotated hexagons create the illusion of a smooth and continuous curve along all edges.

By implementing these changes, you can achieve a hexagon with fully curved edges, resulting in a more visually appealing and aesthetically pleasing shape.
