CSS Introduce
CSS stands for Cascading Style Sheets. It is a programming language used to style HTML elements. It controls the layout, design, and appearance of a web page.
Here are some key points of CSS:
Selects elements: CSS uses selectors to target specific HTML elements.
Applies styles: Once an element is selected, CSS applies various styles to it, such as font, color, size, spacing, and layout.
Cascading: CSS follows a cascading rule, meaning that if multiple styles are applied to the same element, the most specific style takes precedence.
External, internal, and inline styles: CSS can be written in external files, within the HTML document, or directly within HTML elements.
Properties and values: CSS uses properties and values to define styles. For example, the color property can have values like red, blue, or #FF0000.
Units of measurement: CSS uses units of measurement like pixels (px), ems, rems, percentages, and more.
Inheritance: CSS styles can be inherited by child elements, meaning they inherit the styles of their parent elements unless overridden.
By understanding these key points, you can effectively use CSS to create visually appealing and well-structured web pages.
