HTML and CSS: Introduction
HTML (HyperText Markup Language) and CSS (Cascading Style Sheets) are fundamental components of web design and development. HTML defines the structure of a page, while CSS controls its appearance. These two technologies are very important for creating web pages together.
This article provides information about basic concepts of HTML and CSS, their working principles, and how to create a simple web page.
Basic Concepts of HTML
HTML is a markup language used for web pages. It is used to define the structure of a page. The main elements of HTML are as follows:
- Tabs: Each element on an HTML page is created using tabs.
- Attributes: Used to provide additional information for tags.
- Elements: Content located within the tags.
For example, the following code shows a simple structure of an HTML page:
<html>
<head></head>
<body>
<h1>Hello, World!</h1>
</body>
</html>
Basic Concepts of CSS
CSS is used to control the appearance and design of web pages. With CSS you can define colors, fonts, layouts, and many other attributes. The basic concepts of CSS are as follows:
- Selectors: Define which HTML elements receive styles.
- Rules: Styles associated with selectors.
- Inline, Internal, and External CSS: How you can apply CSS on a page.
The following example shows how to change the background color of a page using CSS code:
body {
background-color: lightblue;
}

<h1>Hello, World!</h1>
