Attribute definitions

align = top|bottom|left|right [CI]

Deprecated. For visual user agents, this attribute specifies the position of the caption with respect to the table. Possible values:

• top: The caption is at the top of the table. This is the default value.
• bottom: The caption is at the bottom of the table.
