Can I Apply CSS :hover Styles to SVG `` Elements?

Can you Apply :hover Style to SVG USE Element?

Styling SVG elements embedded within a section using the CSS :hover pseudoclass can be challenging. Despite their presence in the DOM, these elements cannot be targeted directly due to the way SVGs are structured.

Understanding the Issue:

The SVG specification specifies that the cloning of referenced elements in the section into the DOM tree does not include any CSS properties or cascade values. This means that selectors in CSS2 cannot be applied to cloned elements within the referenced elements, making it impossible to directly target these elements with :hover styles.

Partial Support in Firefox:

While most browsers do not support direct targeting of virtual elements within a reference, Firefox offers partial support. It allows for the modification of fill or stroke colors by assigning currentColor to the referenced element and then altering the color property of the element on hover.

Limited Browser Support:

However, this approach has limited compatibility and should only be used if specifically targeting Firefox. For cross-browser compatibility, other methods must be employed.

Alternative Solutions:

One method to address this issue is by using JavaScript to manipulate the SVG DOM at runtime and dynamically apply hover styles to virtual elements. While this approach provides more flexibility, it requires additional scripting and may not be suitable for all scenarios.

Another solution involves utilizing elements in combination with masks. By defining a clip path in the section and linking it to a mask applied to the element, you can achieve pseudo-hover effects without directly targeting the virtual elements. This method provides better browser support and is more inline with SVG principles.

Conclusion:

Applying the :hover pseudoclass to embedded SVG elements using the tag is not straightforward due to limitations in the SVG specification. Partial support exists in Firefox, but for cross-browser compatibility, alternative approaches such as JavaScript manipulation or masking should be considered.
