21.6.2018
When we produce a PNG image, we use an <img> tag or a CSS background, and that's about it. It is dead simple and guaranteed to work.
PNG is way simpler to use in HTML than SVG
Unfortunately, the same cannot be said for SVG, despite its many advantages. Although you're spoiled for choices...
What is SVG good for?
21.6.2018
Y'all probably wouldn't be surprised if I told you it's pretty awesome for icons, and icon systems. SVG icon systems can, and perhaps should be quite easy. I'm a fan of just inlining those suckers, particularly when they are pretty simple.
