What is HTML, What is it Used For? What Can Be Done with HTML?

HTML is a standard markup language invented by Tim Berners-Lee, used to create and structure web pages. See details. You will find answers to all your questions related to topic What is HTML, What is it Used For? What Can Be Done with HTML? in the continuation of the text.

What is HTML?

HTML (Hypertext Markup Language) is a markup language used to create web pages. Invented in the early 1990s by Tim Berners-Lee, this language forms the foundation of the internet. HTML, as a markup language, defines how web pages are structured and displayed by browsers. Simply put, HTML creates the skeleton of web pages.

Significant versions of HTML and their years:

• HTML 1.0: The first version of HTML was developed by Tim Berners-Lee in 1991. It was used to describe simple web pages in the early days of the internet.
• HTML 2.0: Released in 1995, it was the first standardized version of HTML, defining basic web functionalities.
• HTML 3.2: Released in 1997, it added more formatting tags and provided more flexibility in web design.
• HTML 4.01: Introduced in 1999, the 1999 version improved integration with CSS and transitioned to a more semantic markup structure.
• XHTML 1.0: Developed in 2000, it was an XML-based version of HTML 4.01 and introduced stricter syntax rules.
• XHTML 1.1: Released in 2001, it moved XHTML 1.0 to a modular structure.
• HTML5: Officially completed in 2014, HTML5 is the most significant update to HTML, introducing tags that natively support video, audio, and other multimedia elements and providing stronger APIs for web applications.

What HTML Is Used For: Key Features and Functions

HTML is a markup language used to create the structure and content of web pages. It organizes texts, links, images, and other content for display by internet browsers. Key functions and features of HTML include:

• Defines the basic structure of a web page. It specifies how the page's title, header tags, paragraphs, images, links, and other content will be placed, helping to create the layout and structure of the page.
• Used for text formatting. Header tags (e.g., <h1>, <h2>, <h3>) specify text style and importance. The paragraph tag (<p>) defines text paragraphs.
• HTML allows you to add links to other web pages or resources. The <a> tag defines links and directs users to different pages or websites.
• The <img> tag enables the addition of images to web pages. HTML can also be used to embed media elements like video and audio.
• HTML is used to create web forms, allowing users to interact through text input, selecting options, or uploading files. Forms enable users to submit information or create queries.
• Supports different types of lists such as unordered lists (<ul>), ordered lists (<ol>), and definition lists (<dl>), which help in organizing and structuring content.
• HTML defines basic layout, but CSS (Cascading Style Sheets) is used to control the appearance of the page in detail. CSS allows adding colors, fonts, sizes, and other style properties to HTML elements.
• With HTML5, semantic tags were introduced to better express the meaning of the page. Tags like <header>, <nav>, <article>, <section> make the page structure and content more meaningful.
• Ensures web pages are properly read by assistive technologies like screen readers, facilitating understanding for disabled users.
• HTML contains structural information that helps search engines index and rank web pages. Elements like header tags, meta descriptions, and others are very important for SEO optimization.

How to Use HTML: Working Logic and Examples

Learning HTML and starting to create basic web pages is quite easy. The basic things you need to start with HTML are quite limited.

What You Need to Start

Here's what you need to get started:

1. Computer: Any modern computer is sufficient to write and test HTML codes.
2. Text Editor: A simple text editor is enough to write HTML codes. You can start with simple editors like Notepad (Windows) or TextEdit (Mac). If you are looking for more advanced alternatives, you can choose popular code editors like Visual Studio Code, Atom, Sublime Text.
3. Web Browser: You will need a web browser to view and test your HTML files. You can use a modern browser like Google Chrome, Mozilla Firefox, Safari, or Microsoft Edge.
4. Basic Computer Knowledge: Knowing basic computer operations like saving files, opening different file formats will be useful.
5. Internet Access (Optional): Internet access is beneficial for utilizing various resources while learning HTML. Online courses, tutorial videos, documents, and community forums can accelerate your learning process.

Writing Code and Examples

Step 1: Basic HTML Structure

At the beginning of every HTML file, there is a basic structure:

<!DOCTYPE html>
<html>
<head>
    <title>Page Title</title>
</head>
<body>
    Content will go here
</body>
</html>

Step 2: Adding Header and Paragraph Header and paragraph tags are fundamental parts of the page content:

<h1>This is a Header</h1>
<p>This is a paragraph.</p>

Step 3: Adding Link and Image Links and images add interactivity and visuals to the page:

<a href="https://www.example.com">This is a link</a>
<img src="image.jpg" alt="Image Description">

Step 4: Creating Lists Lists are a good way to present information in an organized manner:

<ul>
    <li>List Item 1</li>
    <li>List Item 2</li>
</ul>
<ol>
    <li>Ordered List Item 1</li>
    <li>Ordered List Item 2</li>
</ol>

Step 5: Adding Table Tables are used to organize data in columns and rows:

<table border="1">
    <tr>
        <th>Header 1</th>
        <th>Header 2</th>
    </tr>
    <tr>
        <td>Data 1</td>
        <td>Data 2</td>
    </tr>
</table>

Step 6: Creating Form Forms are used to collect information from the user:

<form action="#">
    <label for="name">Name:</label>
    <input type="text" id="name" name="name"><br><br>
    <input type="submit" value="Submit">
</form>

The above steps form the basics of creating a simple web page with HTML. For more complex features and advanced designs, you can refer to HTML documentation and web development resources.

What Are the Most Commonly Used HTML Codes?

Here are some common HTML codes and their uses:

• <!DOCTYPE html>: Defines an HTML5 document.
• <html>: The root element of an HTML document.
• <head>: Contains the document's metadata.
• <title>: Defines the title of the web page; visible in the browser tab.
• <body>: Contains the main content of the web page.
• <h1> to <h6>: Header tags; <h1> is the largest, <h6> is the smallest.
• <p>: Paragraph tag.
• <a href="...">: Used to create a hyperlink. "..." contains the URL or a target.
• <img src="..." alt="...">: Used to add images. 'src' specifies the image source, 'alt' specifies alternative text.
• <ul>, <ol>, <li>: Used to create unordered (<ul>) and ordered (<ol>) lists; <li> defines list items.
• <div>: A general-purpose container used for segmentation or grouping.
• <span>: Used to style small sections of content.
• <table>, <tr>, <td>: Used to create tables. <table> defines the table, <tr> rows, and <td> cells.
• <form>: Creates a form to collect user input.
• <input>: Defines various types of inputs (text, password, radio buttons, etc.) within a form.
• <button>: Creates a clickable button.

HTML Color Codes

Color codes are frequently used in HTML and CSS for background, text colors, and other design elements. In HTML, colors are typically defined in two main ways: by names and by color codes. Color codes provide more precise and varied color options. There are two popular color code formats: Hexadecimal (Hex) codes and RGB (Red, Green, Blue) codes.

Hexadecimal Color Codes:

Hex color codes start with a # symbol followed by a six-digit number and/or letter combination. The first two characters represent red, the middle two green, and the last two blue. For example:

• Black: #000000
• White: #FFFFFF
• Red: #FF0000
• Green: #00FF00
• Blue: #0000FF
• Yellow: #FFFF00
• Orange: #FFA500
• Gray: #808080

RGB Color Codes:

RGB color codes are defined using the rgb() function and include three numbers. These numbers represent the intensity of red, green, and blue color components, respectively. Each component can take a value from 0 (none) to 255 (full intensity). Examples:

• Black: rgb(0, 0, 0)
• White: rgb(255, 255, 255)
• Red: rgb(255, 0, 0)
• Green: rgb(0, 255, 0)
• Blue: rgb(0, 0, 255)
• Yellow: rgb(255, 255, 0)
• Orange: rgb(255, 165, 0)
• Gray: rgb(128, 128, 128)

In addition to RGB codes, RGBA codes also exist; this format includes information about transparency (alpha value) along with colors. For example, rgba(255, 0, 0, 0.5) creates a semi-transparent red color.

The Pros and Cons of HTML

HTML is one of the foundational pillars of the web development world and is a basic language that every web developer should know. However, like any technology, HTML has its own pros and cons.

Pros:

• HTML is supported by all web browsers, making it one of the standard languages of the internet.
• It has a simpler structure compared to other programming languages and is easier to learn.
• Can be easily integrated with other technologies like CSS and JavaScript, enabling the creation of dynamic and interactive web pages.
• Excellent for search engine optimization (SEO). When used correctly, it helps search engines understand and index content more easily.
• There are numerous development tools and resources available for HTML, making it easier for developers.

Cons:

• Designed for creating static pages and does not offer dynamic features or advanced design options on its own.
• Advanced functions like database operations, server-side processes, or user input cannot be directly performed with HTML; it must be combined with languages like PHP, JavaScript.
• Different web browsers may interpret HTML codes in various ways, leading to inconsistent displays.

What is CSS?

CSS (Cascading Style Sheets) is a style language used to define the appearance and format of web pages. Used in conjunction with HTML, it arranges the layout, color, font, and other visual elements of web pages. CSS separates content (HTML) from design (style), making web development more flexible and manageable.

What are the Differences Between HTML and CSS?

Role and Purpose:

• HTML: Defines the structure and content of a web page (e.g., texts, links, images).
• CSS: Defines the design and presentation of a web page (e.g., colors, fonts, spacing).

Usage Area:

• HTML: Used for page structure and content hierarchy.
• CSS: Controls the visual style and layout of the page.

Syntax:

• HTML: Uses tags and elements to create document structure.
• CSS: Defines style rules using selectors and property-value pairs.

Dependency and Relationship:

• HTML provides a foundation without which CSS would be non-functional.
• CSS adds style to HTML elements, enhancing their appearance.

File Types:

• HTML: Stored in files with .html or .htm extensions.
• CSS: Stored in files with .css extensions.

Integration:

• CSS can be directly embedded in HTML files or linked to external CSS files.
• CSS can be written independently of HTML and used across multiple HTML files.

In summary, while HTML forms the "skeleton" of a web page, CSS adds style and visual appeal to this "skeleton". Together, they create modern, visually attractive, and user-friendly websites.
