Attributes

Basic

align

Horizontal alignment in cells. Possible values are:

  • left: Left-justify text. This is the default value for table data cells.
  • center: Center-justify text. This is the default value for table header cells.
  • right: Right-justify text.
  • justify: Left- and right-justify text.
  • char: Align text around a specific character.
valign

Vertical alignment in cells. Possible values are:

  • top: Cell data is flush with the top of the cell.
  • middle: Cell data is centered vertically within the cell. This is the default value.
  • bottom: Cell data is flush with the bottom of the cell.
  • baseline: All cells in the same row as a cell whose valign attribute has this value will have their textual data positioned so that the first text line occurs on a baseline common to all cells in the row.

Advanced

char
(Character) This attribute specifies a single character within a text fragment to act as an axis for alignment. The default value for this attribute is the decimal point character for the current language as set by the xml:lang attribute. For example, the period (".") in English and the comma (",") in French.
charoff
(Length) When present, this attribute specifies the offset to the first occurrence of the alignment character on each line.

Common core attributes

class
(NameTokens) This attribute assigns a class name or set of class names to an element. Any number of elements may be assigned the same class name or set of class names. Multiple class names must be separated by white space characters. Class names are typically used to apply CSS formatting rules to an element.
id
(ID) This attribute assigns an ID to an element. This ID must be unique in a document. This ID can be used by client-side scripts (such as JavaScript) to select elements, apply CSS formatting rules, or to build relationships between elements.
title
(Text) This attribute offers advisory information. Some Web browsers will display this information as tooltips. Assistive technologies may make this information available to users as additional information about the element.

Common internationalization attributes

xml:lang
(NameToken) This attribute specifies the base language of an element's attribute values and text content.
dir

This attribute specifies the base direction of text. Possible values:

  • ltr: Left-to-right
  • rtl: Right-to-left

ondblclick

onmousedown
