Description

xbStyle is an JavaScript Object that is used to expose the style properties of an Element in a cross browser fashion. Netscape Navigator 4.x, Gecko based browsers such as Netscape 6.x, Internet Explorer 4+ and Opera 5+ are supported.

Cross Browser Support

DOM based browser sniffing is used whereever possible to allow any standards compliant browser to support xbStyle. User Agent based browser sniffing is used only in restricted parts of the API that require differentiation of particular implementations.

For browsers that support CSS2 Properties such as, Gecko based browsers and Internet Explorer 4 and above, xbStyle simply queries and manipulates the properties of the style object.

Modern browsers which support the W3 DOM Standard can access any element via document.getElementById and use xbStyle to manipulate the Style properties in a cross browser fashion. Note that the ability to query or modify Style properties depends up on the CSS display and position properties. For example in CSS 2, height and width are not defined for non-replaceable Elements with display: inline such as SPAN and as a result xbStyle can not manipulate these properties for

For Netscape 4, xbStyle manipulates the corresponding properties of a Layer object.

Notes

Script Location/Invocation.  xbStyle must be able to locate references to the HTML Elements whose style properties it will query or modify. In order to do this the script referencing the HTML Elements must either occur in an ONLOAD handler for the document or must occur after the HTML Element is defined in the document.

CSS Units.  xbStyle requires that all CSS length properties use pixel units. If you use non-pixel units, xbStyle will ignore that length. If you wish to be notified of any such errors, turn on debugging at the beginning of xbStyle.js. This will report any errors to a separate Debug window.

Netscape Navigator 4.  xbStyle was originally designed to provide limited cross browser support for CSS properties that could reliably be used in Netscape Navigator 4.x and Internet Explorer 4.x. It has since been extended to support additional CSS properties which are not supported by Netscape Navigator 4.x.

Due to a bug in Netscape Navigator 4, you must include an empty script block at the beginning of your HTML document in order that the Object based sniffing work properly. Please see the examples for samples of this technique.

In order to use xbStyle with Netscape Navigator 4, you must code any HTML Element which you wish to manipulate as a DIV with either absolute or relative positioning. Netscape Navigator 4 will convert these positioned DIVs into Layers which can be manipulated via the xbDOM and xbStyle APIs. You can use the xbGetElementById and xbGetElementsByName functions available in xbDOM in order to locate references.

Netscape Navigator 4.x will not fully display the background properties for a DIV unless a border is specified. If you do not wish to have a border, you should still code a fractional border width in order to force Netscape Navigator 4 to fully display the background.

Netscape Navigator 4 is not capable of changing the background color of a DIV if the background color was specified via the CSS property background-color either in a CSS rule or in a STYLE attribute. In order to manipulate the background color of a DIV using Netscape Navigator 4, you must not code a background color in the CSS. Instead, set the background color using the xbStyle setBackgroundColor method.

Netscape Navigator 4 is not capable of changing the foreground color of text.

Clipping.  Note that although the CSS 2 Specification states that the top, right, bottom, and left properties are offsets from the respective sides of the element's box, an errata modifies the CSS 2 specification to match the behavior of Netscape 4.x, 6.x, Internet Explorer and Opera where the right property can be consider the clipping region width and the bottom property can be consider the clipping region height. Also note that although the specification states that clipping only occurs if the overflow CSS property is not set to visible, Gecko/Netscape 6.x, Netscape 4.x and Internet Explorer all browsers currently clip elements even if the overflow property is set to visible. Finally, the specification states that any element can be clipped, however in Gecko/Netscape 6.x and Internet Explorer only absolutely positioned items can be clipped. Note that Opera will report the clip settings however it is not possible to clip an element in Opera 5 or 6.

Opera 5+.  Opera 5 and 6 support a very limited set of the DOM for HTML or CSS. Please see the Opera documentation for more details on the limitations of current implementations of Opera.

Development and Debugging

See xbDebug manpage for more information on using the xb Debugging facilities.

Examples

Example 1. Basic Example

This example illustrates the basics of using xbStyle. Note how an empty script block is included before any other scripts. This prevents the occurence of a bug in Netscape 4.x where Object based sniffing in external scripts fails. Also note the use of a border with a width of .1px. This is due to a bug in Netscape 4.x where the background color does not fill the entire boundary of an Element unless a border is specified.

The scripts required to use xbStyle are split into separate files for discussion and maintenance purposes. You can consolidate them for deployment if you wish.

The remaining examples all use two positioned DIVs with varying values for position and with properties specified either using a CLASS or via a STYLE attribute.

Each example comes in a NO DOCTYPE version which will exercise Quirks Mode and an HTML 4.01 Strict DOCTYPE vesion which will exercise Standards Mode in Gecko based browsers, Internet Explorer 5 on Macintosh and Internet Explorer 6

Example 2.  Absolutely Positioned Div

NO DOCTYPE HTML 4.01 Strict

This example illustrates the behavior of an absolutely positioned Element using an Inline Style attribute but without a background color. Netscape 4.x can only set a background color if the background color has not been set via CSS.

NO DOCTYPE

HTML 4.01 Strict

This example illustrates the behavior of an absolutely positioned Element using an Inline Style attribute but with a background color. Netscape 4.x can only set a background color if the background color has not been set via CSS.

Note that this example does not depend upon the browser's ability to calculate the effective values for style attributes since they are specified directly in the Inline Style attribute.

Example 4.  Absolutely Positioned Div using CSS Class

NO DOCTYPE

HTML 4.01 Strict

This example illustrates the behavior of an absolutely positioned Element using a CSS Class but with a background color. Netscape 4.x can only set a background color if the background color has not been set via CSS.

setInnerHTML(String sHtml)

replace the contents of this element with the specified HTML

Arguments:  String sHtml markup

getEffectiveValue(String propname)

returns the effective value of a CSS property after the cascade and as a result of any modifications via script. Note that W3 CSS DOM compliant browsers such as Netscape 6 and other Gecko based browsers use the standard method getComputedStyle to retrieve effective values while Internet Explorer uses the currentStyle object. Opera and Netscape Navigator maintain the effective values as part of their style objects.

Arguments:  String propname is the name of the CSS DOM property not the CSS 2 property name. For example, to get the background color for an element, you would pass 'backgroundColor' to getEffectiveValue rather than 'background-color'. Also note that any CSS property supported by a browser can be returned via this method. Properties that are not supported by a particular browser will return the empty string.

Returns:  String Effective CSS property value

Note: Gecko Support.  Netscape 6.1, Netscape 6.2, and other Gecko based browsers prior to release 0.9.6 do not correctly calculate the clip property or the top property for non absolutely positioned elements. These browsers therefore return the actual value of HTMLElement.style.clip and the non-standard property HTMLElement.offsetTop in these circumstances.

Note:  All getXXX methods of xbStyle use this method to return the effective values of properties.
