How do I create a heading?

You can create six sizes of headings - <h1>...<h6> in HTML - by typing, from the beginning of a line, three dashes (-), from one to six plus signs (+), a space, and your heading text. The FAQ questions on this page are created with: ---+++ Have a question?.

Text enclosed in angle brackets like <filename> is not displayed. How can I show it as it is?

Changed:
<
<
TWiki interprets text as HTML. The '<' and '>' characters are used to define HTML commands. Text contained in angle brackets is interpreted by the browser if it's a valid HTML instruction, or ignored if it isn't - either way, the brackets and its contents are not displayed.

TWiki interprets text as HTML, and the '<' and '>' characters define where HTML commands start and end. Text inside angle brackets is treated as HTML, and ignored if it doesn't actually do anything - either way, the brackets and its contents are not displayed.
  If you want to display angle brackets, enter them as HTML codes instead of typing them in directly:
  • &lt; = <

Text I enter gets wrapped around. How can I keep the formatting as it is?

Changed:
<
<
TWiki interprets text as HTML, so you can use the preformatted HTML text option to keep the new line of text as is. Enclose the text in <pre> </pre>, or in TWiki's own <verbatim> </verbatim> tags:

The pre tag is standard HTML; verbatim is a special TWiki tag that also forces text to fixed font mode, and also prevents other tags and TWiki shortcuts from being expanded.

Can I include images on a page?

 
Changed:
<
<
Yes, this is possible. The easiest way of including images is to attach a GIF, JPG or PNG file to a topic and then to include it with text %ATTACHURL%/myImage.gif . FileAttachment has more.

Yes. The easiest way is to attach a GIF, JPG or PNG file to a topic and then to place it with: %ATTACHURL%/myImage.gif. This works only for the page that the image is attached to.
 
Changed:

There are actually two ways of including inline images.

To place an image on any page, ther are two ways of including inline images.
  1. Using URL ending in .gif, .jpg, .jpeg, .png
Changed:
<
<
This is a simple and automatic way of including inline images. Simply write the URL of the image file, this will create the inline image for you. Note: The images must be accessible as a URL.

You can upload images directly to your server with FTP access. You can also attach image files to a topic - you could even create a dedicated image topic, like ImageLibrary - and then link to the images directly:
  • Attach pic.gif to Someweb.SomeTopic
    Display with http://twiki.npl.illinois.edu/pub/Someweb/SomeTopic/pic.gif
 2. Using <img> tag
Changed:
<
<
This is a manual process where you have more control over the rendering of the image. Use the <img> tag of HTML to include GIF, JPG and PNG files. Note: The display of the topic is faster if you include the WIDTH and HEIGHT parameters that have the actual image size. http://www.htmlhelp.com/reference/wilbur/special/img.html has more on inline images.

Can I write colored text?

Changed:
<
<
Sure. The quickest way is to use the <font color="colorCode"> and </font> tags - they're HTML tags that work in any browser, (although they've been phased in the latest version).

You can also use a style attribute: style="color:#ff0000", placed in most HTML tags - span is an all-purpose choice: "<span style="color:#ff0000">.

You can also use the up-to-date style attribute - ex: style="color:#ff0000" - placed in most HTML tags. span is an all-purpose choice: "<span style="color:#ff0000">CoLoR</span>. Only old (like 3.x IE & NS) browsers have a problem with style.
  "colorCode" is the hexadecimal RGB color code, which is simply Red, Green and Blue values in hex notation (base 16, 0-F). For pure red, the RGB components are 255-0-0 - full red (255), no green or blue. That's FF-0-0 in hex, or "#ff000=" for Web page purposes. For a basic color selection (you can StandardColor names instead of hex code in the =font tag only):
