Formatting posts

The most basic formatting is leaving a blank line to start a new paragraph. For short posts containing only words, this is usually all you need. However, more advanced formatting is available. Formatting can be done directly by adding HTML elements, and/or with Markdown.

HTML

The pages you see are ultimately in HTML. Arbitrary HTML can't be allowed because that could break lots of things. However, a certain subset is specifically allowed to provide some control over formatting without giving you the capability to break the larger page.

tags

HTML tags start with <name> and usually end with </name>. Whatever you put between the starting and ending part gets effected by that tag.

The allowed tags are:

  • <a href="URL">text</a>

    Makes text a clickable link. Clicking goes to URL.

  • <img src="URL">

    Inserts the image at URL in-line.

  • <p>

    Starts a new paragraph. The ending </p> is allowed but usually not required.

  • <b>text</b>, <strong>text</strong>

    Writes the text in bold --> b-text, strong-text

  • <i>text</i>, <em>text</em>

    Writes the text in italics --> i-text, em-text

  • <hr>

    Draws a horizontal line.

  • <h1>text</h1> ... <h6>text</h6>

    Headings, with weight 1 to 6. Weight 1 is a top level heading, with the remaining numbers successively more subordinate:

    Heading 1


    Heading 2

    Heading 3

    Heading 4

    Heading 5
    Heading 6
  • <blockquote>text</blockquote>

    Shows the text in a separate block, visually set off from the surrounding text. Use this to show text that you are quoting from elsewhere:

    Four score and seven years ago, not much of any significance happened. This is more rambling to show how long text is wrapped. Blah, blah, blah.
  • <strike>text</strike>, <del>text</del>

    Writes text with a line thru it to show that it is crossed out or deleted:

    strike text
    del text

  • <code>text</code>

    Writes the text in-line in fixed space font:

    In-line code text --> In-line code text <-- In-line code text.

  • <pre>text</pre>

    Writes a block of text in fixed space font. Use this for source code to keep it from getting wrapped and formatted to oblivion:

    begin
      level := TankLevel(sludge.tank);
      thresh := sludge.thresh_high;
      if EpaInspector then begin
        thresh := sludge.thresh_legal;
        end;
      if level > thresh then begin
        PumpOn (sludge);
        end;
    
  • <br>

    Inserts a "break" in flowed text. The following text starts on a new line.

  • <ol> ... </ol>, <ul> ... </ul>

    Lists. OL (ordered list) creates a numbered list. Each entry will have a successive number. UL (unordered list) just puts a bullet in front of each list entry.

    Add list entries with the LI (list item) tag, below.

  • <li>text

    Starts a new entry in the current list. This works for both numbered (OL) and unnumbered (UL) lists.

  • <sup>text</sup>

    Writes text as a superscript --> P = I2R

  • <sub>text</sub>

    Writes text as a subscript --> hFE = 50

  • <section>text</section>

    Defines a separate section of the document.

Special characters

The HTML &xxx; special characters are available. Click on the heading for more information.

Markdown

This site also supports the markdown language CommonMark. This is intended to be a little easier to type than HTML, but be aware that some simple text sequences can have effects on formatting.

Briefly, the markdown language elements are:

  • Bold: **text** is text
  • Italic: *text* or _text_ is text
  • Code/monospace: `text` is text
  • Links: [name](url) cause name to be a link to url
  • Strikethrough: ~~text~~ is text
  • Blockquotes: > text is

    text

  • Bullets: start your lines with * or -
  • Numbered lists: start your lines with 1., 2., etc.
  • Headers: start your line with # for H1, ## for H2, etc. Must have a space between # and the start of your text.
  • Horizontal line: --- on a line on its own.
  • footnotes: use [^1], [^2], etc., inline, and add [^1]: words to the bottom of your post for automatic formatting and linking.
