Welcome to the Wiki Tricks page. Here you can find how to reproduce some of the cool functionality you've seen on this wiki.

# The Basics

## Images

To put an image on a page, like: , use the code:

[[Image:Example.jpg]]


after you have uploaded it. You can also specify that you want the image to be aligned right or left of text by writing:

[[Image:Example.jpg|right]] OR  [[Image:Example.jpg|left]]


and you can scale the image by giving it a pixel number, like this

[[Image:Example.jpg|350px]]


produces something like

For links to pages in this wiki such as "Newton's Basin", use the code:

[[Page Name| text you want shown]] OR [[Page Name]]


the latter code is used when the text you want shown is simply the page name. And, yes, when specifying the page name, cAsE MaTTerS.

For a link to an outside webpage, such as wikipedia, use the code:

[PageURL textYouWantShown] OR [PageURL]


the second will just show the URL as the link.

## Splitting Text into Columns

### Two Columns

• To format text into two columns, do the following:
 <div style="float: left; width: 50%">
Info for first column
</div><div style="float: left; width: 50%">
Info for second column
</div>


Info for first column

Info for second column

### Three Columns

• And, to get text into three columns, use the following code:
 <div style="float: left; width: 33%">
Info for first column
</div><div style="float: left; width: 33%">
Info for second column
</div><div style="float: left; width: 33%">
Info for third column
</div>



Info for first column

Info for second column

Info for third column

## Mouse Overs

To generate a , use the code:

<balloon title="Text you want in balloon.">text for mouseover</balloon>


To generate a with images, math, and links.

 <balloon title="load:Title of Content">text for mouseover</balloon>
<span id="Title of Content" style="display:none">Text, links, math, images you want in balloon</span>


## Hide/Show

### Basic Hide/Show

To hide a block of text, for example:

Like this!

use the code:

{{hide|Text you want hidden}}


if your text contains an "=" sign, you must use the code:

{{hide|1=Text you want hidden}}


otherwise it appears as {{1}} in your page, which is silly.

### "Hide This"

The HideThis option allows you to specify what it is you want to hide. For example,

{{HideThis|1=<text to follow hide/show>|2=<text to hide>}}

### Switch

If you have two sets of text that you'd like to switch between--for example, one that's just images and one that's the images and the text that goes with them, you can do this by using the Switch function. The code for this is:

{{Switch|Click to expand|Click to hide|The text shown by default|The text that you want to show when you click the first link!}}


which produces:

The text shown by default

The text that you want to show when you click the first link!

If you have several equations that you want to fit on multiple lines with the equals sign lined up in a column, you can use the template "AlignEquals":

Example:

<template>AlignEquals |e1l=3/2 |e1r=1.5 |e2l=2/3 |e2r=0.3333... |e3l=13/8 |e3r=1.625 </template>

To do this, you should use the code:

 <template>AlignEquals
|e1l=3/2
|e1r=1.5
|e2l=2/3
|e2r=0.3333...
|e3l=13/8
|e3r=1.625
</template>



where you fill in e1l with the content of the left side of your first equation, e1r with the content on the right side of your first equation, etc. Currently, the template handles up to 10 equations.

# Embedding Videos, Applets, Etc.

## Embedding Videos

You can embed youtube videos by using the code

{{#ev:youtube|xI2eEcqz46E}}


where the xI2eEcqz46E represents the id assigned by youtube (you can find it in the URL of your video (e.g. www.youtube.com/watch?v=xI2eEcqz46E).

...and you can embed parts of youtube videos by using the code:

{{#ev:tubechop|xI2eEcqz46E&start=10&end=20}}


where start and end are the value (in seconds) of where in you want the clip to start and end.

## Embedding Flash Movies

To embed flash movies (.swf files) on a page, first upload your file, then use the code:

<flash>file=filename.swf|attribute=value|...</flash>


"attributes" include width,height,scale,id. For example:

flash>file=cool.swf|width=200|height=300|bgcolor=#FDE742|scale=exactfit</flash></wiki>


## Embedding Java Applets

To embed Java Applets on a page, first upload your file(s) and then use the code:

<java_applet code="Example.class"  height="150" width="150" archive="Example.jar" />
