CSS stands for Cascading Style Sheet, introduced by the World Wide Web Consortium (W3C), developed by Hakon Wium Lie. CSS was initially released on December 17, 1996.
HTML was originally designed as a simple way of presenting information for sharing documents online with few styles, but if you want your HTML page to be more attractive and colorful, CSS gives you a great advantage.
CSS allows you to specify various style properties for a given HTML element, such as color, background, font, etc. CSS was to improve web presentation capabilities. It allows web designers to define the look and feel of their web pages. CSS is designed to enable the separation of content and presentation. This separation can improve content accessibility and reduce complexity.
