css - Introduction to CSS

CSS (Cascading Style Sheets) is a language for styling and laying out web pages. While HTML organizes text, CSS specifies its visual display by regulating elements like as colors, fonts, and layouts.

Why CSS Matters

Improves Design: Improves the appearance of websites.

Consistency: Ensures consistency in styling across numerous pages.

Responsive Design: Layouts are automatically adjusted to fit various screen sizes.

How CSS Works

CSS applies styling to HTML components based on rules.

Each rule consists of:

Selectors: Targets HTML elements.

Declarations: Specifies properties (e.g., color, font-size) and their values.

Example:

p {

  color: blue;

  font-size: 16px;

}

Applying CSS

Inline CSS: Styles within the HTML element.

<p style="color: red;">Text</p>

Internal CSS: In the <style> tag within HTML.

<style> p { color: green; } </style>

External CSS: Linked in a separate file.

<link rel="stylesheet" href="styles.css">
