CSS

Selectors and Declarations:

• Selectors: CSS uses selectors to target HTML elements. Selectors can target elements based on their type, class, ID, attributes, and relationships with other elements.
• Declarations: Once an element is selected, CSS allows you to declare styling properties such as color, font size, margin, padding, etc.
• Box Model:The CSS box model describes the layout and spacing of elements on a web page. It consists of the content area, padding, border, and margin.
• Layout:CSS is crucial for defining the layout of a web page. It includes properties to control the positioning of elements, such as position, display, and float.
• Responsive Design: CSS supports responsive design, allowing developers to create layouts that adapt to different screen sizes and devices. Techniques like media queries are commonly used for this purpose.
• Flexbox and Grid:CSS Flexbox and Grid layout are powerful tools for creating flexible and responsive page layouts. They provide a way to design complex, grid-based structures with ease.
• Colors and Backgrounds:CSS allows you to set colors for text, backgrounds, borders, etc. It supports various color formats, including named colors, hexadecimal, RGB, and HSL.
• Typography: CSS controls the styling of text, including properties for font family, size, weight, style, line height, and more. Web fonts can be integrated to enhance typography.
• Transitions and Animations: CSS enables the creation of smooth transitions and animations. Transition properties allow gradual changes between states, while keyframe animations provide more complex and custom animations.
• Selectors and Combinators: CSS selectors and combinators allow developers to target specific elements or groups of elements, providing a fine level of control over styling.
• Vendor Prefixes: In the past, different browsers required different prefixes for certain CSS properties. While this practice is becoming less common, it’s essential to be aware of vendor prefixes for older browser support.
• CSS Preprocessors: Developers often use CSS preprocessors like Sass or Less to extend the capabilities of CSS. These preprocessors introduce variables, nesting, and functions to make styling more efficient and maintainable.
