Introduction to HTML and CSS

What is HTML?

HTML stands for HyperText Markup Language and is the foundation of web pages. It structures content using elements like headings, paragraphs, links, and images. HTML provides the basic framework but does not define the design or appearance of a webpage.

What is CSS?

CSS stands for Cascading Style Sheets and is used to control the design of web pages. CSS allows you to change colors, fonts, layouts, and other stylistic features, making the webpage visually engaging.

CSS Properties

The following are important CSS properties:

Background Color

The background-color property sets the background color of an element. Example:

body {
    background-color: lightblue;
}
    

Text Color

The color property changes the text color, not the background.

CSS Classes

A CSS class is a reusable style that can be applied to multiple elements. It is defined using a period (.) before the class name.

.container {
    width: 80%;
    margin: auto;
}
