cx

« SVG Attribute reference home

For the <circle> and the <ellipse> element, this attribute define the x-axis coordinate of the center of the element. If the attribute is not specified, the effect is as if a value of "0" were specified.

For the <radialgradient> element, this attribute define the x-axis coordinate of the largest (i.e., outermost) circle for the radial gradient. The gradient will be drawn such that the 100% gradient stop is mapped to the perimeter of this largest (i.e., outermost) circle. If the attribute is not specified, the effect is as if a value of 50% were specified.

Usage context

<coordinate>

A <coordinate> is a length in the user coordinate system that is the given distance from the origin of the user coordinate system along the relevant axis (the x-axis for X coordinates, the y-axis for Y coordinates). Its syntax is the same as that for <length>.

Within the SVG DOM, a <coordinate> is represented as an SVGLength or an SVGAnimatedLength.

Example
