š 10 Advanced HTML Attributes That Feel Like Cheat Codes
As developers, we've all been there: installing a heavy NPM package or writing 50 lines of JavaScript for a simple feature, only to realize HTML could have done it natively in one line.
Modern HTML is far more powerful than many developers realize. Some built-in attributes can improve performance, accessibility, user experience, and even replace JavaScript entirely for certain tasks.
