SVG <view> Element

SVG stands for Scalable Vector Graphic. It can be used to make graphics and animations like in HTML canvas. The <view> element is used to alter the attributes of viewbox of the original SVG element. It is used by referencing the element’s id as the target fragment of a URL. It provides features like zoom in or zoom out of the rendered content.

Syntax:

<view viewBox="" preserveAspectRatio="" viewTarget=""/>

Attributes:

viewBox: It defines the coordinates which fits to the drawing region.
preserveAspectRatio: It indicates how an element with a viewBox providing a given aspect ratio must fit into a viewport with a different aspect ratio.
viewTarget: It consists of list of id values for the elements that are the main focus of the view.
