direction - CSS: Cascading Style Sheets 编辑

The direction CSS property sets the direction of text, table columns, and horizontal overflow. Use rtl for languages written from right to left (like Hebrew or Arabic), and ltr for those written from left to right (like English and most other languages).

Note that text direction is usually defined within a document (e.g., with HTML's dir attribute) rather than through direct use of the direction property.

The property sets the base text direction of block-level elements and the direction of embeddings created by the unicode-bidi property. It also sets the default alignment of text, block-level elements, and the direction that cells flow within a table row.

Unlike the dir attribute in HTML, the direction property is not inherited from table columns into table cells, since CSS inheritance follows the document tree, and table cells are inside of rows but not inside of columns.

The direction and unicode-bidi properties are the two only properties which are not affected by the all shorthand property.
