> ### <a name="How do I make a separator?"></a> How do I make a separator?
>
> Create a separator - a horizontal rule - by entering three dashes at the beginning of a blank line: `---`. You can enter more than three if you like, for a more visible separator in edit mode: <br />`--------------`
>
> ----
>
> ### <a name="How do I create a heading?"></a> How do I create a heading?
>
> You can create six sizes of headings - &lt;h1&gt;...&lt;h6&gt; 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?`.
>
> - You can insert a nested table of contents, generated from headings, by placing `%TOC%` wherever you like on a page (see [[TWikiVariables]] for more `%TOC%` options).
>
> ----
>
> <a name="TextEnclosed"></a>
>
> ### <a name="Text enclosed in angle brackets"></a><a name="Text enclosed in angle brackets "></a> Text enclosed in angle brackets like &lt;filename&gt; is not displayed. How can I show it as it is?
>
> TWiki interprets text as HTML, and the '&lt;' and '&gt;' 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;` = `<`<br />`&gt;` = `>`
>
> - **_You enter:_** `(a &gt; 0)`
>     **_Result:_** `(a > 0)`
>
> ----
>
> ### <a name="Some words appear highlighted, w"></a> Some words appear highlighted, with a "?" link at the end. How can I prevent that?
>
> A question mark after a word is a link to a topic that doesn't yet exist - click it to create the new page. This is a TWiki feature - typing a [[MeaningfulTitle]] in a comment is an invitation for someone else to add a new branch to the topic.
>
> To prevent auto-linking - say you want to enter a word like JavaScript (the proper spelling!) - prefix the [[WikiStyleWord]] with the special TWiki HTML tag `<nop>`:
>
> - `<nop>WikiStyleWord` displays as WikiStyleWord
>
> ----
>
> ### <a name="How can I write fixed font text?"></a> How can I write fixed font text?
>
> The quickest way is to enclose the text in equal signs:
>
> - **_You enter:_** `Proportional text, =fixed font=, proportional again.`
>     **_Result:_** Proportional text, `fixed font`, proportional again.
>
> ----
>
> ### <a name="Text I enter gets wrapped around"></a> Text I enter gets wrapped around. How can I keep the formatting as it is?
>
> TWiki interprets text as HTML, so you can use the `preformatted` HTML option to keep the new line of text as is. Enclose the text in &lt;pre&gt; &lt;/pre&gt;, or in TWiki's own &lt;verbatim&gt; &lt;/verbatim&gt; tag:
>
>     This text will keep its format as it is:
>     <verbatim>
>       Unit      Price Qty  Cost
>       -------  ------  ---  ------
>       aaa              12.00   3      36.00
>     </verbatim>
>
> The `pre` tag is standard HTML; `verbatim` is a special TWiki tag that forces text to fixed font mode, and also prevents other tags and TWiki shortcuts from being expanded.
>
> ----
>
> ### <a name="How do I create tables?"></a> How do I create tables?
>
> There are three possibilities:
>
> 1. Use Wiki rule with "|" vertical bars.
> 2. Use HTML tables with &lt;table&gt;, &lt;tr&gt;, &lt;td&gt; tags.
> 3. Use preformatted text with &lt;verbatim&gt; tags.
>
> **1\. Use Wiki rule with "|" vertical bars**
>
> - Example text: <br />`| cell A1 | cell B1 | cell C1 |`<br />`| cell A2 | cell B2 | cell C2 |`
> - Example output: <table border="1" cellpadding="0" cellspacing="0">
>   <tr>
>     <td> cell A1 </td>
>     <td> cell B1 </td>
>     <td> cell C1 </td>
>   </tr>
>   <tr>
>     <td> cell A2 </td>
>     <td> cell B2 </td>
>     <td> cell C2 </td>
>   </tr>
> </table>
>
> **2\. Use HTML tables with &lt;table&gt;, &lt;tr&gt;, &lt;td&gt; tags**
>
> This is a manual process using HTML commands.
>
> **_You enter:_**
>
>     <table border="1">
>       <tr>
>        <th> Head A  </th> <th> Head B  </th>
>       </tr><tr>
>        <td> Cell A2 </td> <td> Cell B2 </td>
>       </tr><tr>
>        <td> Cell A3 </td> <td> Cell B3 </td>
>       </tr>
>     </table>
>
> **_Result:_**
>
> <table border="1">
>   <tr>
>     <th> Head A </th>
>     <th> Head B </th>
>   </tr>
>   <tr>
>     <td> Cell A2 </td>
>     <td> Cell B2 </td>
>   </tr>
>   <tr>
>     <td> Cell A3 </td>
>     <td> Cell B3 </td>
>   </tr>
> </table>
>
> **3\. Use preformatted text with &lt;verbatim&gt; tags**
>
> See [["Text enclosed..."|Main/WebHome#TextEnclosed]]
>
> ----
>
> ### <a name="Can I include images on a page?"></a> Can I include images on a page?
>
> Yes. The easiest way is to [[attach|Main/FileAttachment]] 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.
>
> To place an image on any page, ther are two ways of including inline images.
>
> **1\. Using URL ending in .gif, .jpg, .jpeg, .png**
>
> 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|Main/WebHome#ImgUpload]] as a URL.
>
> - **_You enter:_** ` TWiki http://www.dementia.org/twiki//view/TWiki/TWikiLogos/twikilogo88x31.gif logo.`<br />**_Result:_** TWiki ![twikilogo88x31.gif](http://www.dementia.org/twiki//view/TWiki/TWikiLogos/twikilogo88x31.gif) logo.
>
> <a name="ImgUpload"></a> You can upload images directly to your server with FTP access. You can also [[attach|Main/FileAttachment]] 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`<br /> Display with <code>http://www.dementia.org/twiki//view/Someweb/SomeTopic/pic.gif</code>
>
> **2\. Using &lt;img&gt; tag**
>
> This is a manual process where you have more control over the rendering of the image. Use the &lt;img&gt; 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.
>
> - **_You enter:_** `TWiki <img src="http://www.dementia.org/twiki//view/TWiki/TWikiLogos/twikilogo88x31.gif" width="88" height="31" border="0" alt="logo" /> logo.`<br />**_Result:_**<br /> TWiki <img src="http://www.dementia.org/twiki//view/TWiki/TWikiLogos/twikilogo88x31.gif" width="88" height="31" alt="logo" /> logo.

>
> ### <a name="Can I write colored text?"></a> Can I write colored text?
>
> [[TWikiPreferences]] defines some commonly used colors: **%YELLOW% %YELLOW%%ENDCOLOR%, %RED% %RED%%ENDCOLOR%, %PINK% %PINK%%ENDCOLOR%, %PURPLE% %PURPLE%%ENDCOLOR%, %TEAL% %TEAL%%ENDCOLOR%, %NAVY% %NAVY%%ENDCOLOR%, %BLUE% %BLUE%%ENDCOLOR%, %AQUA% %AQUA%%ENDCOLOR%, %LIME% %LIME%%ENDCOLOR%, %GREEN% %GREEN%%ENDCOLOR%, %OLIVE% %OLIVE%%ENDCOLOR%, %MAROON% %MAROON%%ENDCOLOR%, %BLACK% %BLACK%%ENDCOLOR%, %GRAY% %GRAY%%ENDCOLOR%, %SILVER% %SILVER%%ENDCOLOR%** and **%ENDCOLOR%**.
>
> - **_You enter:_** `%RED% red text %ENDCOLOR% and %GREEN% green text %ENDCOLOR%`
>     **_Result:_** %RED% red text %ENDCOLOR% and %GREEN% green text %ENDCOLOR%
>
> **_Note:_** `%<color>%` text must end with `%ENDCOLOR%` . If you want to switch from one color to another one you first need to end the active color with `%ENDCOLOR%`, e.g. write `%RED% some text %ENDCOLOR% %GREEN% more text %ENDCOLOR%`.
>
> If you need more colors you can use HTML, like `<font color="#ff0000"> red text </font>`. 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 &amp; NS) browsers have a problem with `style`.
>
> The code 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. [[StandardColors]] lists basic colors.
