Using Styled Components to change the color of an SVG's stroke

I have an SVG I'm using as an <img> tag. Using Styled Components I am trying to get to a point where I change the stroke color upon hover.

I imported the SVG:

import BurgerOpenSvg from '../../images/burger_open.svg';

I Created a Styled Components for it:

   const BurgerImageStyle = styled.img`
    &:hover {     
        .st0 {
          stroke: red;
        }
    }
`;

And I use it:

<BurgerImageStyle alt="my-burger" src={BurgerOpenSvg}/>

The result is, my SVG is displayed correctly, but no color change upon hovering.

Source for the SVG I use:

<svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" 
     viewBox="0 0 38 28.4" style="enable-background:new 0 0 38 28.4;" xml:space="preserve">
<style type="text/css">
    .st0{fill:none;stroke:#221f1f;stroke-width:2;stroke-miterlimit:10;}
</style>
<g>
    <g id="XMLID_7_">
        <line class="st0" x1="0" y1="1" x2="38" y2="1"/>
    </g>
    <g id="XMLID_6_">
        <line class="st0" x1="0" y1="14.2" x2="38" y2="14.2"/>
    </g>
    <g id="XMLID_5_">
        <line class="st0" x1="0" y1="27.4" x2="38" y2="27.4"/>
    </g>
</g>
</svg>

The SVG Renders as follows:

Is it even possible to update the class on an SVG loaded in an <img> tag? or must it be inline <svg> tag?

Solution

  • If you are looking to avoid writing separate components or copying your raw SVG file, consider react-inlinesvg;

    https://github.com/gilbarbara/react-inlinesvg

    import React from "react";
import styled from "styled-components";
import SVG from "react-inlinesvg";
import radio from "./radio.svg";

interface SVGProps {
  color: string;
}

const StyledSVG = styled(SVG)<SVGProps>`
  width: 24px;
  height: 24px;
  & path {
    fill: ${({ color }) => color};
  }
`;

export default function App() {
  const color = "#007bff";
  return <StyledSVG color={color} src={radio} />;
}
