From time to time you need to recalibrate your brain by experimenting with new technologies, by tracing down the performance of a certain feature or by reconsidering the environment of your project. While I’m generally not a proponent of inlined CSS, we now will use it for a third-party script we are providing to avoid style leakages. The point here is that this decision won’t harm performance as it’s an asynchronously loaded script.
The other thing I always assumed but never got confirmed was that CSS filters slow down the rendering of a page massively. But as it turns out, when you research this properly, there’s only a barely noticeable difference to unfiltered images. Don’t hesitate to try out new things, only make sure that it’s the best solution when you put it to production.
