Web page

A web page is a digital document accessible through a web browser , typically written in HTML and often enhanced with CSS and JavaScript to provide structure , style , and interactivity.

Note

Web pages are the building blocks of the World Wide Web, allowing users to access and interact with information online.

Key Components of a Web Page

HTML Structure

HTML (HyperText Markup Language) provides the basic structure of a web page using tags.

1. Head Section

The head section contains metadata and resources that are not displayed directly on the page but are essential for its functionality.

Example

Title Tag: Sets the title of the web page displayed in the browser tab.
Meta Tags: Provide information about the page, such as the character set, author, and description.
Link Tags: Connect external resources like CSS files.
Script Tags: Include or reference JavaScript files.

2. Body Section

The body section contains the visible content of the web page.

Example

Headings: Defined by <h1> to <h6> tags, they structure the content hierarchically.
Paragraphs: Defined by <p> tags, they organize text into readable blocks.
Images: Embedded using the <img> tag.
Links: Created with the <a> tag to navigate to other pages or resources.
Lists: Ordered (<ol>) and unordered (<ul>) lists organize items.

3. Cascading Style Sheets (CSS)

CSS is used to style and layout web pages.

Example

Inline Styles: Applied directly to HTML elements using the style attribute.
Internal Styles: Defined within a <style> tag in the head section.
External Styles: Linked through a separate CSS file.

4. JavaScript

Paywall

(on a website) an arrangement whereby access is restricted to users who have paid to subscribe to the site.
