Indentation defines the spacing between the beginning of a block-level element and the left margin or gutter in all languages with left to right text direction. In languages with right to left text direction indentation defines the spacing between the beginning of the element and the right margin.
Note that due to the nature of this formatting option, indentation can only be applied to a block-level element, like a paragraph, a list item, or a
div element. If the paragraph spans across multiple lines of text, each line will appear at the same indentation level.
