“If you just sit and observe, you will see how restless your mind is. If you try to calm it, it only makes it worse, but over time it does calm, and when it does, there’s room to hear more subtle things. You see so much more than you could see before. It’s a discipline; you have to practice it.”
Steve Jobs

border-start-start-radius

The border-start-start-radius CSS property defines a logical border radius on an element, which maps to a physical border radius that depends on the element's writing-mode, direction, and text-orientation. This is useful when building styles to work regardless of the text orientation and writing mode.
