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.

What is 'render-blocking CSS'?
Jun 24, 2025 am 12:42 AM
CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.

CSS: When Does Case Matter (and When Doesn't)?
Jun 19, 2025 am 12:27 AM
In CSS, selector and attribute names are case-sensitive, while values, named colors, URLs, and custom attributes are case-sensitive. 1. The selector and attribute names are case-insensitive, such as background-color and background-Color are the same. 2. The hexadecimal color in the value is case-sensitive, but the named color is case-sensitive, such as red and Red is invalid. 3. URLs are case sensitive and may cause file loading problems. 4. Custom properties (variables) are case sensitive, and you need to pay attention to the consistency of case when using them.
