Frequently Asked Questions

How do I make a perfect circle?
To make a perfect circle, the element must be a perfect square (equal width and height), and the border-radius must be set to 50%.
What is a Pill shape in CSS?
A pill shape is commonly used for buttons. You can achieve this by setting the border-radius to an extraordinarily high pixel value, like 9999px.
How does Tailwind handle custom border radii?
In Tailwind CSS, you can use arbitrary values for complex border radii. Our tool formats this as rounded-[value] so you can paste it directly into your HTML class names.
