The cx attribute defines the x-axis coordinate of a center point.
You can use this attribute with the following SVG elements:
[!NOTE] As a geometry property, {{cssxref("cx")}} can also be used as CSS property for
<circle>and<ellipse>.
html,
body,
svg {
height: 100%;
}
<svg viewBox="0 0 300 100" xmlns="http://www.w3.org/2000/svg">
<radialGradient cx="25%" id="myGradient">
<stop offset="0" stop-color="white" />
<stop offset="100%" stop-color="black" />
</radialGradient>
<circle cx="50" cy="50" r="45" />
<ellipse cx="150" cy="50" rx="45" ry="25" />
<rect x="205" y="5" width="90" height="90" fill="url(#myGradient)" />
</svg>

For {{SVGElement('circle')}}, cx defines the x-axis coordinate of the center of the shape.
[!NOTE] The x-axis coordinate of the center of the
<circle>can also be defined with the {{cssxref("cx")}} geometry property. If set in CSS, thecxproperty value overrides thecxattribute value.
For {{SVGElement('ellipse')}}, cx defines the x-axis coordinate of the center of the shape.
[!NOTE] The x-axis coordinate of the center of the
<ellipse>can also be defined with the {{cssxref("cx")}} geometry property. If set in CSS, thecxproperty value overrides thecxattribute value.
For {{SVGElement('radialGradient')}}, cx defines the x-axis coordinate of the end circle for the radial gradient.
