wml::std::page(3) EN Tools wml::std::page(3) NAME
wml::std::page - Standard HTML Page Header and Footer SYNOPSIS
#use wml::std::page <page [attributes]> [<page_end>] <head>...</head> <title>...</title> DESCRIPTION
This include file provides the new "<page>" tag which is a advanced combination of the HTML "<body>" and "<head>" container tags. The idea is to provide complete header and footer tags via one single tag while providing new features like page indentation, easy title specification and setup of default values for the page colors. ATTRIBUTES
"title" This is a shorthand for the container tag "<title>". The value of this attribute is placed in the "<head>" section of the page, surrounded with the "<title>" tag. "indent" This sets the indentation level of the page in units of "<blockquote>"'s. Default is no indentation. Setting "indent" to a value of N means the page is surrounded by N "<blockquote">> tags. The attribute "indent=1" or "indent=2" usually provides the best readable layout. "background" This just corresponds to the same attribute of the "<body>" tag and sets the background image. This is per default not used. "bgcolor" This just corresponds to the same attribute of the "<body>" tag and sets the background color. Default is "bgcolor="#ffffff"" (white). "text" This just corresponds to the same attribute of the "<body>" tag and sets the text color. Default is "text="#000000"" (black). "link" This just corresponds to the same attribute of the "<body>" tag and sets the normal hyperlink color. Default is "text="#333399"" (medium blue). "alink" This just corresponds to the same attribute of the "<body>" tag and sets the color for activated hyperlinks. Default is "text="#9999ff"" (light blue). "vlink" This just corresponds to the same attribute of the "<body>" tag and sets the color for already visited hyperlinks. Default is "text="#000066"" (dark blue). "color" When setting "color="none"", the five previous attributes are not put into the "<body>" tag. "onload" This just corresponds to the same attribute of the "<body>" tag and sets a JavaScript even handler which is activated after page was loaded. This is per default not used. "info" This automatically puts a "<info style=meta>" tag into the "<head>" section of the page. See wml::std::info(3) for more details. "slices" This enables the creating of three slices: "WML_STDPAGE_HEAD", "WML_STDPAGE_BODY" and "WML_STDPAGE_FOOT". These can be used later in Pass 9 (Slice) for cutting out parts of the page. :html:ATTR=STR :body:ATTR=STR The ``ATTR=STR'' pairs are passed along to the "<html>" and "<body>" HTML tags. OTHER COMMANDS
This module implements two new macros, called "<title>"..."</title>" and "<head>"..."</head>". The first one defines the title of the page, and the second appends its body into the HEAD section of the HTML documents. Its main purpose is to add meta-tags, either directly or with the help of wml::std::info(3). AUTHOR
