I used a very simple trick, make a new CSS rule for your nuko images that contains "image-rendering: pixelated;" this will make the image appear as sharp pixels instead ! It's normal if they appear smaller than me, the original image is 20x20 pixels but I display them at 200% size so they look bigger and are easier to preview.

thank you sm ! I'm so glad my collection is helping people out hehe

according to MDN: The HTML element is deprecated and its use is strongly discouraged. If you must create the effect of scrolling text or continuous elements, consider using CSS animations with CSS transforms instead of elements to smoothly animate content.

When a feature is depracated that means it's not longer supported and shouldn't be used. It will still work in the name of backwards compatibility with old or abandoned websites. You can still use it but theoritecally it could be deleted any day from now on. So it's better to use css animations

Sorry, I don't think many except developers actually still use RSS. That's the only reason it refuses to die.

if you want to! many people are starting to use feed readers again!

RSS is awesome, you should definitely try it! I love keeping up with blogs across the web using RSS
