goog.style

Clears the background image of an element in a browser independent manner.

Retrieves the computed background color string for a given element. The string returned is suitable for assigning to another element's background-color, but is not guaranteed to be in any particular string format. Accessing the color in a numeric form may not be possible in all browsers or with all input.

If the background color for the element is defined as a hexadecimal value, the resulting string can be parsed by goog.color.parse in all supported browsers.

Whether named colors like "red" or "lightblue" get translated into a format which can be parsed is browser dependent. Calling this function on transparent elements will return "transparent" in most browsers or "rgba(0, 0, 0, 0)" in WebKit.

Gets the computed border widths (on all sides) in pixels

Gets the border box size for an element.

Returns a bounding rectangle for a given element in page space.

Gets the cascaded style value of a node, or null if the value cannot be computed (only Internet Explorer can do this).

Returns clientLeft (width of the left border and, if the directionality is right to left, the vertical scrollbar) and clientTop as a coordinate object.

Returns the position of the event or the element's border box relative to the client viewport. If an event is passed, and if this event is a "touch" event, then the position of the first changedTouches will be returned.

Returns the viewport element for a particular document

Retrieves the computed value of the box-sizing CSS attribute. Browser support: http://caniuse.com/css3-boxsizing.

Retrieves the computed value of the cursor CSS attribute.

Retrieves the computed value of the overflow-x CSS attribute.

Retrieves the computed value of the overflow-y CSS attribute.

Retrieves the computed value of the position CSS attribute.

Retrieves a computed style value of a node. It returns empty string if the value cannot be computed (which will be the case in Internet Explorer) or "none" if the property requested is an SVG one and it has not been explicitly set (firefox and webkit).

Retrieves the computed value of the text-align CSS attribute.

Retrieves the computed value of the CSS transform attribute.

Retrieves the computed value of the z-index CSS attribute.

Calculate the scroll position of container with the minimum amount so that the content and the borders of the given element become visible. If the element is bigger than the container, its top left corner will be aligned as close to the container's top left corner as possible.

Gets the content box size for an element. This is potentially expensive in all browsers.

Returns the x,y translation component of any CSS transforms applied to the element, in pixels.

Gets value of explicitly-set float CSS property on an element.

Returns the font face applied to a given node. Opera and IE should return the font actually displayed. Firefox returns the author's most-preferred font (whether the browser is capable of displaying it or not.)

Returns the font size, in pixels, of text in an element.

Returns a Coordinate object relative to the top-left of an HTML document in an ancestor frame of this element. Used for measuring the position of an element inside a frame relative to a containing frame.

Returns the units used for a CSS length measurement.

Gets the computed margins (on all sides) in pixels.

Returns the first parent that could affect the position of a given element.

Gets the opacity of a node (x-browser). This gets the inline style opacity of the node, and does not take into account the cascaded or the computed style for this node.

Gets the computed paddings (on all sides) in pixels.

Returns a Coordinate object relative to the top-left of the HTML document. Implemented as a single function to save having to do two recursive loops in opera and safari just to get both coordinates. If you just want one value do use goog.style.getPageOffsetLeft() and goog.style.getPageOffsetTop(), but note if you call both those methods the tree will be analysed twice.

Returns the left coordinate of an element relative to the HTML document

Returns the top coordinate of an element relative to the HTML document

Gets the offsetLeft and offsetTop properties of an element and returns them in a Coordinate object

Returns the position of an element relative to another element in the document. A relative to B

Returns the scroll bar width (represents the width of both horizontal and vertical scroll).

Gets the height and width of an element, even if its display is none.

Specifically, this returns the height and width of the border box, irrespective of the box model in effect.

Note that this function does not take CSS transforms into account. Please see goog.style.getTransformedSize.

Retrieves an explicitly-set style value of a node. This returns '' if there isn't a style attribute on the element or if this style property has not been explicitly set in script.

Gets the height and width of an element, post transform, even if its display is none.

This is like goog.style.getSize, except:

1. Takes webkitTransforms such as rotate and scale into account.
2. Will return null if `element` doesn't respond to `getBoundingClientRect`.
3. Currently doesn't make sense on non-WebKit browsers which don't support webkitTransforms.

Calculates the viewport coordinates relative to the page/document containing the node. The viewport may be the browser viewport for non-iframe document, or the iframe container for iframe'd document.

Calculates and returns the visible rectangle for a given element. Returns a box describing the visible portion of the nearest scrollable offset ancestor. Coordinates are given relative to the document.

Installs the style sheet into the window that contains opt_node. If opt_node is null, the main window is used.

Test whether the given element has been shown or hidden via a call to #setElementShown.

Note this is strictly a companion method for a call to #setElementShown and the same caveats apply; in particular, this method does not guarantee that the return value will be consistent with whether or not the element is actually visible.

Returns true if the element is using right to left (rtl) direction.

Returns true if the element is set to be unselectable, false otherwise. Note that on some platforms (e.g. Mozilla), even if an element isn't set to be unselectable, it will behave as such if any of its ancestors is unselectable.

Parses a style attribute value. Converts CSS property names to camel case.

Changes the scroll position of container with the minimum amount so that the content and the borders of the given element become visible. If the element is bigger than the container, its top left corner will be aligned as close to the container's top left corner as possible.

Sets the border box size of an element. This is potentially expensive in IE if the document is CSS1Compat mode

Sets the content box size of an element. This is potentially expensive in IE if the document is BackCompat mode.

Shows or hides an element from the page. Hiding the element is done by setting the display property to "none", removing the element from the rendering hierarchy so it takes up no space. To show the element, the default inherited display property is restored (defined either in stylesheets or by the browser's default style rules).

Caveat 1: if the inherited display property for the element is set to "none" by the stylesheets, that is the property that will be restored by a call to setElementShown(), effectively toggling the display between "none" and "none".

Caveat 2: if the element display style is set inline (by setting either element.style.display or a style attribute in the HTML), a call to setElementShown will clear that setting and defer to the inherited style in the stylesheet.

Sets CSS float property on an element.

Set the height of an element. Sets the element's style property.

Sets 'display: inline-block' for an element (cross-browser).

Sets the opacity of a node (x-browser).

Moves an element to the given coordinates relative to the client viewport.

Sets the top/left values of an element. If no unit is specified in the argument then it will add px. The second argument is required if the first argument is a string or number and is ignored if the first argument is a coordinate.

Sets 'white-space: pre-wrap' for a node (x-browser).

There are as many ways of specifying pre-wrap as there are browsers.

CSS3/IE8: white-space: pre-wrap; Mozilla: white-space: -moz-pre-wrap; Opera: white-space: -o-pre-wrap; IE6/7: white-space: pre; word-wrap: break-word;

Sets the content of a style element. The style element can be any valid style element. This element will have its content completely replaced by the safeStyleSheet.

Sets the width/height values of an element. If an argument is numeric, or a goog.math.Size is passed, it is assumed to be pixels and will add 'px' after converting it to an integer in string form. (This just sets the CSS width and height properties so it might set content-box or border-box size depending on the box model the browser is using.)

Sets a style value on an element.

This function is not indended to patch issues in the browser's style handling, but to allow easy programmatic access to setting dash-separated style properties. An example is setting a batch of properties from a data object without overwriting old styles. When possible, use native APIs: elem.style.propertyKey = 'value' or (if obliterating old styles is fine) elem.style.cssText = 'property1: value1; property2: value2'.

Sets the background of an element to a transparent image in a browser- independent manner.

This function does not support repeating backgrounds or alternate background positions to match the behavior of Internet Explorer. It also does not support sizingMethods other than crop since they cannot be replicated in browsers other than Internet Explorer.

Makes the element and its descendants selectable or unselectable. Note that on some platforms (e.g. Mozilla), even if an element isn't set to be unselectable, it will behave as such if any of its ancestors is unselectable.

Set the width of an element. Sets the element's style property.

Shows or hides an element from the page. Hiding the element is done by setting the display property to "none", removing the element from the rendering hierarchy so it takes up no space. To show the element, the default inherited display property is restored (defined either in stylesheets or by the browser's default style rules.)

Caveat 1: if the inherited display property for the element is set to "none" by the stylesheets, that is the property that will be restored by a call to showElement(), effectively toggling the display between "none" and "none".

Caveat 2: if the element display style is set inline (by setting either element.style.display or a style attribute in the HTML), a call to showElement will clear that setting and defer to the inherited style in the stylesheet.

Converts a CSS selector in the form style-property to styleProperty.

Converts a CSS selector in the form styleProperty to style-property.

Reverse of parseStyleAttribute; that is, takes a style object and returns the corresponding attribute value. Converts camel case property names to proper CSS selector names.

Translates the specified rect relative to origBase page, for newBase page. If origBase and newBase are the same, this function does nothing.

Removes the styles added by #installSafeStyleSheet.
