g

Summary

The g element (<g>) is a container element for grouping together related graphics elements.

Overview Table

DOM Interface
SVGElement

The g element (<g>) groups two or more graphics elements or other g elements together to provide document structure. Groups containing the desc and title elements, provide additional semantic information and increase accessibility. When defined inside of a defs element and named using the id attribute, groups can be reused.

Examples

In the following code example, the g element is used to group two elements together. They are then rotated together.



<!DOCTYPE HTML>
<html>
  <head></head>
  <body>
    <svg width="400" height="400">
      <g transform="rotate(30 75 50)">
        <rect x="50" y="50" width="50" height="50" fill="firebrick"/>
        <ellipse cx="100" cy="50" rx="25" ry="50" fill="dodgerblue"/>
      </g>
    </svg>
  </body>
</html>

Standards information

Members

The SVGGElement object has these events:

  • onload: Occurs when the browser has fully parsed the element and all of its descendants.

The SVGGElement object has these methods:

  • getBBox: Gets the bounding box, in current user space, of the geometry of all contained graphics elements.
  • getCTM: Gets the transformation matrix that transforms from the current user units to the viewport coordinate system for the nearestViewportElement object.
  • getScreenCTM: Gets the transformation matrix from the current user units to the screen coordinate system.
  • getTransformToElement: Gets the transformation matrix that transforms from the user coordinate system on the current element to the user coordinate system on the specified target element.
  • hasExtension: Determines if the specified extension is supported.

The SVGGElement object has these properties:

  • className: Gets the names of the classes that are assigned to this object.
  • clipPath: Sets or retrieves a reference to the SVG graphical object that will be used as the clipping path.
  • externalResourcesRequired: Gets a value that indicates whether referenced resources that are not in the current document are required to correctly render a given element.
  • farthestViewportElement: Gets a value that represents the farthest ancestor svg element.
  • focusable: Determines if an element can acquire keyboard focus (that is, receive keyboard events) and be a target for field-to-field navigation actions (such as when a user presses the Tab key).
  • mask: Sets or retrieves a value that indicates a SVG mask.
  • nearestViewportElement: Gets a value that indicates which element established the current viewport.
  • ownerSVGElement: Gets the nearest ancestor svg element.
  • requiredExtensions: Gets a white space-delimited list of required language extensions.
  • requiredFeatures: Gets or sets a white space-delimited list of feature strings.
  • style: Gets a style object.
  • systemLanguage: Gets or sets a comma-separated list of language names.
  • transform: Gets the value of a transform attribute.
  • viewportElement: Gets the element that established the current viewport.
  • xmlbase: Gets or sets the base attribute on the element.
  • xmllang: Gets or sets a value that specifies the language that is used in the contents and attribute values of an element.
  • xmlspace: Gets or sets a value that indicates whether white space is preserved in character data.
