Css For Beginners

What is CSS?

CSS (Cascading Style Sheets) is a stylesheet language used to describe the presentation and layout of web documents written in HTML (Hypertext Markup Language). It allows you to control the colors, fonts, spacing, and overall design of your web pages, ensuring a consistent and visually appealing user experience.

Basic CSS Syntax

In CSS, you select HTML elements and apply styles to them using rules. A CSS rule consists of a selector and a declaration block. Here's the basic syntax:

css

selector {

    property: value;

}

- Selector: Identifies the HTML element(s) to which the styles will be applied.

- Property: Specifies the aspect of the element you want to style (e.g., `color`, `font-size`, `margin`).

- Value: Sets the value for the property (e.g., `red`, `16px`, `10px 20px`).
