1619 | To write fairly well formatted pages you only need to know few things. Most | |
1620 | browsers have a function to read the source code of the page being seen, so | |
1621 | you can imitate various tricks. Here's a very short HTML primer which you | |
1622 | can also view with a browser to see what happens: | |
1623 | ||
1624 | <title>A Title Describing Contents</title> should be on every page. Pages can | |
1625 | have <h1>Very Major Headlines</h1> through <h6>Very Minor Headlines</h6> | |
1626 | <hr> Parts can be separated with horizontal rules. | |
1627 | ||
1628 | <p>Paragraphs only need an opening tag. Line breaks and multiple spaces are | |
1629 | ignored unless the text is <pre>preformatted.</pre> Text can be marked as | |
1630 | <b>bold</b>, <i>italic</i> or <u>underlined</u> using the normal M-g or | |
1631 | Edit/Text Properties/Face commands. | |
1632 | ||
1633 | Pages can have <a name=\"SOMENAME\">named points</a> and can link other points | |
1634 | to them with <a href=\"#SOMENAME\">see also somename</a>. In the same way <a | |
1635 | href=\"URL\">see also URL</a> where URL is a filename relative to current | |
f788776c | 1636 | directory, or absolute as in `http://www.cs.indiana.edu/elisp/w3/docs.html'. |
1caf38eb RS |
1637 | |
1638 | Images in many formats can be inlined with <img src=\"URL\">. | |
