CSS3

CSS3 (Cascading Style Sheets Level 3) is a stylesheet language used to control the appearance and layout of web pages. It works alongside HTML to define how elements such as text, images, buttons, and menus are displayed. CSS3 introduced many advanced features, including animations, transitions, gradients, shadows, flexbox, grid layouts, and responsive design techniques, making it easier to create modern and visually appealing websites. It helps separate a website’s content from its design, improving maintainability and consistency across web pages. CSS3 is an essential technology for web development, enabling developers to build attractive, responsive, and user-friendly websites that work across different devices and screen sizes.
