How Can I Effectively Style Embedded SVGs When Direct CSS Styling Is Limited?

Styling Embedded SVGs: CSS Limitations and Alternative Approaches

Overview

Styling embedded SVGs (Scalable Vector Graphics) can present challenges compared to SVGs included directly in a document. Understanding the limitations and exploring alternative methods is crucial for effective styling.

Direct CSS Styling of Embedded SVGs

When an SVG is embedded using the

object svg {
    fill: #fff;
}

Injecting Styles Using Script

Since embedded SVGs are separate documents, styles can be injected into them using script. The following method assumes the

var svgDoc = yourObjectElement.contentDocument;
var styleElement = svgDoc.createElementNS("http://www.w3.org/2000/svg", "style");
styleElement.textContent = "svg { fill: #fff }";
svgDoc.getElementById("where-to-insert").appendChild(styleElement);

Alternatively, an external stylesheet can be linked using the element:

var svgDoc = yourObjectElement.contentDocument;
var linkElm = svgDoc.createElementNS("http://www.w3.org/1999/xhtml", "link");
linkElm.setAttribute("href", "my-style.css");
linkElm.setAttribute("type", "text/css");
linkElm.setAttribute("rel", "stylesheet");
svgDoc.getElementById("where-to-insert").appendChild(linkElm);

Direct Styling from SVG File

Alternatively, styles can be directly linked or included within the SVG file:

<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet href="my-style.css" type="text/css"?>
<svg xmlns="http://www.w3.org/2000/svg">
  ... rest of document here ...
</svg>

or

<svg xmlns="http://www.w3.org/2000/svg">
  <defs>
    <link href="my-style.css" type="text/css" rel="stylesheet" xmlns="http://www.w3.org/1999/xhtml">
  </defs>
  ... rest of document here ...
</svg>

Additional Option: jquery-svg Plugin

For further flexibility, the jquery-svg plugin provides methods to apply CSS styles and JavaScript scripts to embedded SVGs.
