1. Frame

   Frames allow authors to present document in multiple views. _frameset command replaces the _body command to divide web page into several frames. 'cols' attribute specifies frames that are divided along the column. The 'cols' value specifies the width of each columns. You may specifies any number of columns with length list such as '33%, 67%'. 'rows' attribute specifies frames that are divided along the row. When both rows and cols are set simultaneously _frameset command creates a grid. Frames are created from left to right for the columns and from top to bottom for the rows. _frameset may be nested to any level. 'frameborder' attribute with value '0' will hide the frame border and value '1' will show a 3D border. Finally, 'framespacing' attribute specifies the number of whitespaces between frames.

   The _frame command in the content of _frameset loads the html file from the 'src' attribute value. Its 'name' attribute is an id that allows other commands target this frame. The value '1' of the 'frameborder' attribute draws a border around the frame and the value '0' makes no border. 'marginheight' and 'marginwidth' specify the margin height and width of a frame. The value 'yes' of the 'scrolling' attribute makes browser display a scrolling bar on the frame. The value 'no' will hide the scrolling bar.

   The content of the _noframes command is compabitiable to the browser that does not support the frame.

   _html
     _head
     _title; _quote "Frame"; title_
     head_
     _frameset "cols='33%, 67%' 
       frameborder='0' framespacing='1'"
       _frame "name='index' src='index.html'"
       _frame "name='content' src='content.html'"
     frameset_
     _noframes
       _quote "older browser without frame."

2. Table

   _table is a command to construct a table. The _tr command specifies table row and the _td command specifies table data. _table content may include a _caption command. The attributes of a _table are: (i) 'border' attribute sets the table border with the integer from 0 to n; (ii)'align' attribute controls the horizontal alignment of the table with the value left, right, or center; (iii)'valign' attribute controls the verticle alignment with the value top, bottom, or middle; (iv)boolean 'nowrap' attribute does not wrap the contents in the table. To declare the position of cells, the 'cellspacing' attribute specifies the space between two cells; 'cellpadding' attribute sets the space between the border and the content of a cell; and the 'height' and 'width' attributes specify the height and width of a table respectively. Finally 'bgcolor' attribute specifies the background color of a table.

   To specify visible sides, 'frame' attribute may be one of the value: void, above, below, hsides, vsides, lhs, rhs, box, and border. They represent the none side(default), top side, bottom side, top&bottom side, left&right side, left-hand side, right-hand side, and all four sides respectively. To describe which rules will appear between cells, the 'rules' attribute may have one of a value none, groups, rows, cols, or all. In default when there are no frame and rules attributes, border='0' implies frame='void' and rules='none'; border='2' implies frame='border', rules='all', and border width is 2.

   The _tr command defines a row. Its content may be subdivied into head (_thead), foot (_tfoot), and body (_tbody) sections. To group columns, _colgroup and _col commands define the property of group. _th command specifies a cell head in the _tr. Usually it can be replaced by the _td command that defines a cell (data) in the content. _td command may have the attributes 'align', 'valign', 'nowrap', 'height', 'width', 'bgcolor', and other attributes in the _table. In addition, The 'colspan' attribute allows a cell span its width to one or more cells (default 1). The 'rowspan' attribute spans its height to more cells.

3. List

   Firstly, _ol (order list) command creates a numbered list. Secondly, _ul (unorder list) creates a bulleted list. In their contents, _li represents the marker of an order and unorder list. Finally, _dl creates a definition list where _dt (definition title) and _dd (definition description) are markers for the list elements.

   Lists may be nested and combined with different types. The _ol only 'start' attribute specifies the starting marker of the first item in an ordered list (default 1). The 'type' attribute of _ol may have the value '1', 'a', 'A', 'i', 'I' for arabic numbers, lower alpha, upper alpha, lower roman, and upper roman markers respectively. However, the 'type' attribute in _ul sets the shape of markers with value disc, square, and circle. In addition, the _li only 'value' attribute sets the number of the current list item.

   These presentation attributes are better to be replaced by CSS controls.

   _html
   _head 
     _title; _quote "List"; title_ 
   head_
   _body
     _ul "type='circle'"; # shape of marker
       _li; _quote "First Item"
       _li; _quote "Second Item"
       _li; _quote "Third Item"
     ul_
     _ol "start=2 type='i'"
       # starting marker 2 with lower roman
       _li "value='1'"; _quote "1st Item"	
       # current item
       _li; _quote "2nd Item"
       _li; _quote "3rd Item"
