padding
CSS padding is a shorthand property that defines the space between the element border and the element content. Space, that is, the top, bottom, left, and right padding.
When an element's padding (filling) margin is cleared, the released area will be filled with the element's background color.
Use the padding attribute alone to change the top, bottom, left, and right padding.
The padding shorthand attribute sets the width of all padding of an element, or sets the width of padding on each side. Padding set on inline, non-replaced elements does not affect line height calculations; therefore, if an element has both padding and a background, it may visually extend into other lines and possibly overlap other content. . The element's background extends across the padding. Negative margin values are not allowed. (Learning video sharing: css video tutorial)
