Trying to "transform: rotate()" a <circle> element using styled-components - css

Question

CodeSandbox with example:

I'm trying to rotate 180º a circle element inside an SVG. I'm being able to do it with the regular <circle> tag, but I'm not being able to do it with the styled component styled.circle
LS.Svg_SVG = styled.svg`
border: 1px dotted silver;
width: 100px;
height: 100px;
`;
LS.Circle_CIRCLE = styled.circle`
stroke-dasharray: 289.0272;
stroke-dashoffset: -144.5136;
transform: rotate(180 50 50); /* <------------ IT DOES NOT WORK */
`;
export default function App() {
return (
<React.Fragment>
<LS.Container_DIV>
<LS.Svg_SVG viewBox="100 100">
<circle /* USING REGULAR <circle> */
cx="50"
cy="50"
r="46"
stroke="black"
strokeWidth="8px"
fill="none"
strokeDasharray="289.0272"
strokeDashoffset="-144.5136"
transform="rotate(180 50 50)" /* <----------------- IT WORKS */
/>
</LS.Svg_SVG>
</LS.Container_DIV>
<LS.Container_DIV>
<LS.Svg_SVG viewBox="100 100">
<LS.Circle_CIRCLE /* USING STYLED COMPONENTS */
cx="50"
cy="50"
r="46"
stroke="black"
strokeWidth="8px"
fill="none"
/>
</LS.Svg_SVG>
</LS.Container_DIV>
</React.Fragment>
);
}
The result I'm getting:
They both should be the same. The first one is rotated (using regular <circle>). The second one is not rotated (using styled-components). Even though I'm setting transform: rotate(-180 50 50); in the styled component.

Answer 1

In CSS, units are required (ie. 180deg, 50px)
The SVG-specific version of rotate: rotate(angle, cx, cy), is not supported in the CSS version of transform. You'll need to use transform-origin.
LS.Circle_CIRCLE = styled.circle`
stroke-dasharray: 289.0272;
stroke-dashoffset: -144.5136;
transform: rotate(180deg);
transform-origin: 50px 50px;
