Size Icons - Custom Uploaded SVGs

In an effort to improve performance, I am replacing Font Awesome icons with SVGs uploaded to the Icon block. The sizing I had applied via class no longer seem to work. What is the best way to size these, preferably so I can do so via a class?

You can do it via class, but you’ll need to use the sizing options in the style > layout tab as font icons and actual icons are a little different in behaviour
