Yesterday we looked into making rounded corners on our boxes and even circles with border-radius. My good friend svondervoort replied you could use double border-radius. And he is right. I even used it in my Totoro example.
So why not dive into how you use the double border-radius syntax.
HTML Structure
As for the HTML let’s keep it simple and use one big box.
<div class="box rounded"></div>
Then let’s dive into the syntax, it basically accepts two times the code split with a slash.
.rounded {
border-radius: 40% 40% 30% 30% / 60% 60% 40% 40%;
}
We can use percentages and pixels.
It gets quite complicated I find to do these things from the top of your head, but luckily Adam Kuhn made this awesome playground to ease this.

Browser Support
The border-radius is very well supported, and can safely be used.
