Easy-to-use cross-browser tooltips.
Just include the script at the beginning of the <body> section, and invoke
Tip('Tooltip text') to show and UnTip() to hide the tooltip, from the desired
HTML eventhandlers. Example:
<a onmouseover="Tip('Some text')" onmouseout="UnTip()" href="index.htm">My home page</a>
No container DIV required.
By default, width and height of tooltips are automatically adapted to content.
Is even capable of dynamically converting arbitrary HTML elements to tooltips
by calling TagToTip('ID_of_HTML_element_to_be_converted') instead of Tip(),
which means you can put important, search-engine-relevant stuff into tooltips.
Appearance & behaviour of tooltips can be individually configured
via commands passed to Tip() or TagToTip().

//===================  GLOBAL TOOPTIP CONFIGURATION  =========================//
var tt_Debug	= true		// false or true - recommended: false once you release your page to the public
var tt_Enabled	= true		// Allows to (temporarily) suppress tooltips, e.g. by providing the user with a button that sets this global variable to false
var TagsToTip	= true		// false or true - if true, HTML elements to be converted to tooltips via TagToTip() are automatically hidden;
							// if false, you should hide those HTML elements yourself

// For each of the following config variables there exists a command, which is
// just the variablename in uppercase, to be passed to Tip() or TagToTip() to
// configure tooltips individually. Individual commands override global
// configuration. Order of commands is arbitrary.
// Example: onmouseover="Tip('Tooltip text', LEFT, true, BGCOLOR, '#FF9900', FADEIN, 400)"

config. Above			= false		// false or true - tooltip above mousepointer

config. BgImg			= ''		// Path to background image, none if empty string ''
config. BorderColor		= '#003099'
config. BorderStyle		= 'solid'	// Any permitted CSS value, but I recommend 'solid', 'dotted' or 'dashed'
config. BorderWidth		= 1
config. CenterMouse		= false		// false or true - center the tip horizontally below (or above) the mousepointer
config. ClickClose		= false		// false or true - close tooltip if the user clicks somewhere
config. ClickSticky		= false		// false or true - make tooltip sticky if user left-clicks on the hovered element while the tooltip is active
config. CloseBtn		= true		// false or true - closebutton in titlebar
config. CloseBtnColors	= ['#990000', '#FFFFFF', '#DD3333', '#FFFFFF']	// [Background, text, hovered background, hovered text] - use empty strings '' to inherit title colours
config. CloseBtnText	= '&nbsp;X&nbsp;'	// Close button text (may also be an image tag)
config. CopyContent		= true		// When converting a HTML element to a tooltip, copy only the element's content, rather than converting the element by its own
config. Delay			= 400		// Time span in ms until tooltip shows up
config. Duration		= 0			// Time span in ms after which the tooltip disappears; 0 for infinite duration, < 0 for delay in ms _after_ the onmouseout until the tooltip disappears
config. Exclusive		= false		// false or true - no other tooltip can appear until the current one has actively been closed
config. FadeIn			= 100		// Fade-in duration in ms, e.g. 400; 0 for no animation
config. FadeOut			= 100
config. FadeInterval	= 30		// Duration of each fade step in ms (recommended: 30) - shorter is smoother but causes more CPU-load
config. Fix				= null		// Fixated position, two modes. Mode 1: x- an y-coordinates in brackets, e.g. [210, 480]. Mode 2: Show tooltip at a position related to an HTML element: [ID of HTML element, x-offset, y-offset from HTML element], e.g. ['SomeID', 10, 30]. Value null (default) for no fixated positioning.
config. FollowMouse		= false		// false or true - tooltip follows the mouse

config. Height			= 0			// Tooltip height; 0 for automatic adaption to tooltip content, < 0 (e.g. -100) for a maximum for automatic adaption
config. JumpHorz		= false		// false or true - jump horizontally to other side of mouse if tooltip would extend past clientarea boundary
config. JumpVert		= true		// false or true - jump vertically		"
config. Left			= false		// false or true - tooltip on the left of the mouse
config. OffsetX			= 14		// Horizontal offset of left-top corner from mousepointer
config. OffsetY			= 8			// Vertical offset
config. Opacity			= 100		// Integer between 0 and 100 - opacity of tooltip in percent
config. Padding			= 20		// Spacing between border and content
config. Shadow			= false		// false or true
config. ShadowColor		= '#C0C0C0'

config. TextAlign		= 'left'	// 'left', 'right' or 'justify'
config. Title			= ''		// Default title text applied to all tips (no default title: empty string '')
config. TitleAlign		= 'center'	// 'left' or 'right' - text alignment inside the title bar
config. TitleBgColor	= ''		// If empty string '', BorderColor will be used
config. TitleFontColor	= '#FFFFFF'	// Color of title text - if '', BgColor (of tooltip body) will be used
config. TitleFontFace	= ''		// If '' use FontFace (boldified)
config. TitleFontSize	= ''		// If '' use FontSize
