CSS (Cascading Style Sheets) is a style language used to control the appearance and layout of web pages. While HTML defines the structure and content, CSS specifies its appearance. CSS defines how text, colors, fonts, backgrounds, layouts, images, and other visual elements will look on a web page.
CSS can be added to HTML documents or linked via a separate CSS file. External CSS files are preferred to ensure the same style is applied across all pages of a website. This way, if you want to change a design or style, you only need to change the CSS file, and all related HTML pages will automatically update.
CSS works with a “cascade” structure, determining how an element’s styles interact with and override each other on a page. This feature makes style application more flexible and allows an element to carry multiple style properties simultaneously.
CSS3 is the latest version of CSS, offering many style features and effects previously impossible. For example, CSS3 includes rich graphic features such as rounded borders, shadows, transitions, animations, and more. These features enable web designers to create more impressive and user-friendly websites.
