    padding

    Summary

    The padding CSS property sets the required padding space on all sides of an element. The padding area is the space between the content of the element and its border. Negative values are not allowed.

    The padding property is a shorthand to avoid setting each side separately (padding-top, padding-right, padding-bottom, padding-left).

    • Initial value *Value 'initial-padding' not found in DB*
    • Applies to all elements except table-row-group, table-header-group, table-footer-group, table-row, table-column-group and table-column. It also applies to ::first-letter.
    • Inherited *Value 'inherited-padding' not found in DB*
    • Percentages refer to the width of the containing block
    • Media *Value 'media-padding' not found in DB*
