88 All coordinates are assumed to be numbers in the range 0 to 1

90 the top left corner of the associated image.
|
|
|
91

93
|

94 "default"

102 "rect x, y, w, h"

149 When text flows around a figure or table in the margin, you sometimes want
|
|
|
150 to start an element like a header, paragraph or list below the figure rather
|
|
|
151 than alongside it. The CLEAR attribute allows you to move down unconditionally:
|
|
|
152
|
|
|
153 clear=left move down until left margin is clear
|
|
|
154 clear=right move down until right margin is clear
|
|
|
155 clear=all move down until both margins are clear
|
|
|
156
|
|
|
157 Alternatively, you can decide to place the element alongside the figure just
|
|
|
158 so long as there is enough room. The minimum width needed is specified as:
|
|
|
159
|
|
|
160 clear="40 en" move down until there is at least 40 en units free
|
|
|
161 clear="100 pixels" move down until there is at least 100 pixels free
|
|

162

394 Headers can be numbered, although this is a matter for style sheets.
|
|
|
395 The style sheet controls the numbering style:
|
|
|
396
|
|
|
397 a) whether the parent numbering is inherited, e.g. 5.i.c
|
|
|
398 where 5 is the current sequence number for H1 headers, and
|
|
|
399 1 is the number for H2 headers and 3 for H3 headers.
|
|
|
400
|
|
|
401 b) what style is used for current sequence number
|
|
|
402 e.g. arabic, upperalpha, loweralpha, upperroman, lowerroman
|
|
|
403 or a numbering scheme appropriate for the current language
|
|
|
404
|
|
|
405 The skip attribute is used to skip over sequence numbers for items
|
|
|
406 which have been left out of the list, e.g. skip=3 advances the
|
|
|
407 sequence number past 3 omitted items. The seqnum sets the sequence
|
|
|
408 number to a specified value. Note that the style sheet may take
|
|
|
409 advantage of the sequence number for higher level headers.
|
|
|
410
|
|
|
411 The dingbat or src attributes may be used to specify a bullet like
|
|
|
412 image to be placed adjacent to the header. Defining this in the
|
|
|
413 header element simplifies the document markup and avoids the need
|
|
|
414 to use the clear or needs attribute in the following element to
|
|
|
415 prevent it flowing around this image.

|
|

761
|
|
|
762 bleedleft flush left with the left (window) border
|
|
|
763 left flush left with the left text margin
|
|

764 center centered (text flow is disabled for this mode)
|
|
|
765 right flush right with the right text margin
|
|
|
766 bleedright flush right with the right (window) border
|
|
|
767 justify when applicable the table/figure should stretch
|
|
|
768 to fill space between the text margins
|
|
|
769
|
|
|
770 Note: text will flow around the table or figure if the browser
|
|
|
771 judges there is enough room and the alignment is not centered
|
|
|
772 or justified. The table or figure may itself be part of the
|
|
|
773 text flow around some earlier figure. You can in this case use
|
|
|
774 the clear or needs attributes to move the new table or figure
|
|
|
775 down the page beyond the obstructing earlier figure. Similarly,
|
|
|
776 you can use the clear or needs attributes with other elements
|
|
|
777 such as headers and lists to move them further down the page.

784 The HTML 3.0 table model has been chosen for its simplicity
|
|
|
785 and the ease in writing filters from common DTP packages.
|
|
|
786
|
|
|
787 By default the table is automatically sized according to the
|
|
|
788 cell contents and the current window size. Specifying the columns
|
|
|
789 widths using the colspec attribute allows browsers to start
|
|
|
790 displaying the table without having to wait for last row.
|
|
|
791
|
|
|
792 The colspec attribute is a list of column widths and alignment
|
|
|
793 specifications. The columns are listed from left to right with
|
|
|
794 a capital letter followed by a number, e.g. COLSPEC="L20 C8 L40".
|
|
|
795 The letter is L for left, C for center, R for right alignment of
|
|
|
796 cell contents. J is for justification, when feasible, otherwise
|
|
|
797 this is treated in the same way as L for left alignment.
|
|
|
798 Column entries are delimited by one or more space characters.
|
|
|
799
|
|
|
800 The number specifies the width in en's, pixels or as a
|
|
|
801 fractional value of the table width, as according to the
|
|
|
802 associated units attribute. This approach is more compact
|
|
|
803 than used with most SGML table models and chosen to simplify
|
|
|
804 hand entry. The width attribute allows you to specify the
|
|
|
805 width of the table in pixels, en units or as a percentage
|
|
|
806 of the space between the current left and right margins.
|
|
|
807
|
|
|
808 To assist with rendering to speech, row and column headers
|
|
|
809 can be given short names using the AXIS attribute. The AXES
|
|
|
810 attribute is used to explicitly specify the row and column
|
|
|
811 names for use with each cell. Otherwise browsers can follow
|
|
|
812 up columns and left along rows (right for some languages)
|
|
|
813 to find the corresponding header cells.
|
|
|
814
|
|
|
815 Table content model: Braille limits the width of tables,
|
|
|
816 placing severe limits on column widths. User agents need
|
|
|
817 to render big cells by moving the content to a note placed
|
|
|
818 before the table. The cell is then rendered as a link to
|
|
|
819 the corresponding note.
|
|
|
820
|
|
|
821 To assist with formatting tables to paged media, authors
|
|
|
822 can differentiate leading and trailing rows that are to
|
|
|
823 be duplicated when splitting tables across page boundaries.
|
|
|
824 The recommended way is to subclass rows with the CLASS attribute
|
|
|
825 For example: <TR CLASS=Header>, <TR CLASS=Footer> are used for
|
|
|
826 header and footer rows. Paged browsers insert footer rows at
|
|
|
827 the bottom of the current page and header rows at the top of
|
|
|
828 the new page, followed by the remaining body rows.

1143 <!-- LaTeX like arrays. The COLDEF attribute specifies

1144 a single capital letter for each column determining

1145 how the column should be aligned, e.g. coldef="CCC"
|
|

1146

1147 "L" left

1148 "C" center
|

1149 "R" right
|
|
|
1150
|
|
|
1151 An optional separator letter can occur between columns
|
|
|
1152 and should be one of + - or =, e.g. "C+C+C+C=C".
|
|
|
1153 Whitespace within coldef is ignored. By default, the
|
|
|
1154 columns are all centered.
|
|
|
1155
|
|
|
1156 The ALIGN attribute alters the vertical position of the
|
|
|
1157 array as compared with preceding and following expressions.
|
|
|
1158
|
|
|
1159 Use LDELIM and RDELIM attributes for delimiter entities.
|
|
|
1160 When the LABELS attribute is present, the array is
|
|
|
1161 displayed with the first row and the first column as
|
|
|
1162 labels displaced from the other elements. In this case,
|
|
|
1163 the first element of the first row should normally be
|
|
|
1164 left blank.
|
|
|
1165
|
|
|
1166 Use &vdots; &cdots; and &ddots; for vertical, horizontal
|
|
|
1167 and diagonal ellipsis dots. Use &dotfill; to fill an array
|
|
|
1168 cell with horizontal dots (e.g. for a full row).
|
|
|
1169 Note &ldots; places the dots on the baseline, while &cdots;

1170 places them higher up.
