Icons for Tailwind CSS
Tailwind CSS has revolutionized styling by using utility classes. An ideal icon library for a Tailwind project must respect this paradigm. This means the icons should not have hardcoded fill or stroke colors; instead, they should use "currentColor" so they can be styled entirely via Tailwind text-* classes. Additionally, the sizing should be flexible enough to respond to w-* and h-* utility classes without breaking aspect ratios.
WHY THIS MATTERS
//If an icon library does not support "currentColor", you will find yourself writing custom CSS overrides just to change an icon's hover state or dark mode appearance. Libraries built with Tailwind in mind allow you to control every aspect of the icon (size, color, opacity, transitions) using the exact same utility classes you use for your typography.

DESIGN TIPS
Use the text-* utility (e.g. text-blue-500) to colorize icons that use currentColor
Control icon sizing using standard w-* and h-* classes (e.g. w-6 h-6 for 24px)
Heroicons is built by the Tailwind CSS team and offers the best out-of-the-box integration
For complex hover states, use Tailwind group-hover on the parent button or link

COMMON MISTAKES TO AVOID
