1102 To write fairly well formatted pages you only need to know few things. Most
|
|
|
1103 browsers have a function to read the source code of the page being seen, so
|
|
|
1104 you can imitate various tricks. Here's a very short HTML primer which you
|
|
|
1105 can also view with a browser to see what happens:
|
|
|
1106
|
|
|
1107 <title>A Title Describing Contents</title> should be on every page. Pages can
|
|
|
1108 have <h1>Very Major Headlines</h1> through <h6>Very Minor Headlines</h6>
|
|
|
1109 <hr> Parts can be separated with horizontal rules.
|
|
|
1110
|
|
|
1111 <p>Paragraphs only need an opening tag. Line breaks and multiple spaces are
|
|
|
1112 ignored unless the text is <pre>preformatted.</pre> Text can be marked as
|
|
|
1113 <b>bold</b>, <i>italic</i> or <u>underlined</u> using the normal M-g or
|
|
|
1114 Edit/Text Properties/Face commands.
|
|
|
1115
|
|
|
1116 Pages can have <a name=\"SOMENAME\">named points</a> and can link other points
|
|
|
1117 to them with <a href=\"#SOMENAME\">see also somename</a>. In the same way <a
|
|
|
1118 href=\"URL\">see also URL</a> where URL is a filename relative to current
|
|
|
1119 directory or something like http://www.cs.indiana.edu/elisp/w3/docs.html.
|
|
|
1120
|
|
|
1121 Images in many formats can be inlined with <img src=\"URL\">.
|
|
|
1122
|
|
|
1123 If you mainly create your own documents, `sgml-specials' might be interesting.
|
|

1124 But note that some HTML 2 browsers can't handle '. To work around that
|
|

1125 do:
