Change SVG fill color in :before or :after CSS
css, javascript, jquery, pseudo-element, svg
Solution
Using the `content` property generates (non-exposed) markup functionally equvialent to an svg in an <img> element.
You cannot apply style to elements inside the svg document because:
- styles are not allowed to cascade across documents
- when using <img> (or `content`, or any css image property that references svg) the svg document is not exposed by the browsers due to security concerns
Similar questions, but for `background-image` here and here.
So, to do what you want you must get around the two points above somehow. There are various options for doing that, e.g using inline svg, using filters (applied to the <img>) or generating different svg files (or data URIs), as in your question.
Problem
I have a SVG graphic put like this: ``` a::before { content: url(filename.svg); } ``` When I hover over the tag, I really want the SVG to change the fill color, without loading a new SVG file, as I have now: ``` a:hover::before { content: url(filename_white.svg); } ``` Is this possible to achieve using JavaScript, jQuery or just pure CSS that I am not aware of? Thanks.
