CSS has evolved significantly since its inception. Originally, CSS provided basic styling capabilities that separated web page structure from presentation. Over time, CSS gained more powerful features through specifications like CSS3, and new techniques and frameworks like OOCSS emerged to make CSS more flexible and powerful. Looking ahead, CSS will likely continue advancing with new specifications and tools, though some question if it will be replaced by another technology in the future. CSS has come a long way and will likely remain a core technology for styling web pages.
