AWeb supported HTML

Tags (E-J)

The Mode column in the tables below contains the HTML mode that recognizes the tag or attribute. Elements recognized in strict mode will also be recognized in tolerant mode, but elements marked as tolerant will not be recognized in strict mode.

EM

Tag	Explanation	Mode
<EM> ... </EM>	Specifies emphasized text. Typically rendered in italics.	Strict

EMBED

Tag	Explanation	Mode
<EMBED> ... </EMBED>	Specifies an embedded object to display inlined with the text. The OBJECT element should be used instead because it offers more flexibility.	Tolerant (NS)
Attribute	Explanation	Mode
HEIGHT=nn WIDTH=nn	Specifies the height and the width of the object in pixels. AWeb uses this to reserve enough space for the object, so that once it is loaded no reformatting of the page is needed.	Tolerant (NS)
NAME="name"	Specifies a name for the object.	Tolerant (NS)
SRC="url"	Specifies the address of the object. See A for details.	Tolerant (NS)
name=value	All other attributes are passed as (name, value) pairs to the object.	Tolerant (NS)

FONT

Tag	Explanation	Mode
<FONT> ... </FONT>	Specifies a change in font size or colour.	Strict
Attribute	Explanation	Mode
COLOR=#rrggbb COLOR=colourname	Specifies the colour to render the text in. See colour specifications for a list of valid names.	Strict
SIZE=nn SIZE=+nn SIZE=-nn	Specifies the font size. If `nn` is given, it is an absolute size. Valid sizes are 1 to 7, 1 being the smallest and 7 the largest. If `+nn` or `-nn` is given, it is a change relative to the current BASEFONT or Hn size. Valid range is -6 to +6, but the resulting font size will be adjusted to fall within the range 1 to 7. Note that relative font size changes are not cumulative.	Strict

FRAMESET

Tag

Explanation

Mode

Subdivides the browser window in two or more subwindows.

The FRAMESET element should contain one or more FRAME elements that define the documents to display in the subwindows. Other FRAMESET elements may be included to achieve a more complex subdivision.

A document containing a FRAMESET element should not contain a BODY. For compatibility with browsers that don't support frames, a NOFRAMES element may be included in the document.
