If an element uses box-sizing: border-box and has width: 300px; padding: 20px; what is the content width?

With box-sizing: border-box, the width you set (300px) includes padding and borders. So the content area must fit inside that 300px after subtracting the padding on both sides. The padding is 20px on the left and right, totaling 40px. Subtracting that from 300px gives 260px for the content width. If borders were present, they'd also be included in the 300px, further reducing the content width accordingly. This is why the content width is 260px rather than 300px or other values.
