• Why would you want to do this? If you have the svg code in the file already, then there is no need to put it in a pseudo-class. The whole point of pseudo-classes is to reduce DOM elements when you want to add a bit of content, but in your case if you just use your svg code normally it will be no worse (and probably cleaner) than putting it in a pseudo-class(which is also probably impossible). Unless of course if you want to put your svg code in a bunch of locations, in which case you should just keep your svg code in a separate file like an image
