What is HTML?

Introduction to HTML?

HTML stands for Hypertext Markup Language. It is used to design web pages using a markup language. HTML is a combination of Hypertext and Markup Language. Hypertext defines the link between web pages. A markup language is used to define the text document within the tag which defines the structure of web pages. This language is used to annotate (make notes for the computer) text so that a machine can understand it an manipulate text accordingly. Most markup languages (e.g. HTML) are human-readable. The language uses tags to define what manipulation has to be done on the text.

HTML is a markup language used by the browser to manipulate text, images, and other content, in order to display it in the required format. HTML was created by Tim Berners-Lee in 1991. The first-ever version of HTML was HTML 1.0, but the first standard version was HTML 2.0, published in 1995.

HTML documents consist of a series of HTML tags, enclosed in angle brackets (< >), which are used to define and describe the structure and content of the page. These tags are placed within the overall structure of an HMTL document, which typically includes the '<html>', '<head>', and '<body>' tags.

Here's a basic example of an HTML document:

<!DOCTYPE html>

<html>

<head>

<title>Page Title</title>

</head>

<body>

<h1>Welcome to My Website</h1>

<p>This is a paragraph of text.</p>

<a href="https://www.example.com">Click here</a> to visit a link.

</body>

</html>

In this example:

'<DOCTYPE html>' declares the document type as HTML5.
'<html>' is the root element and contains all other elements.
'<head>' contains meta-information about the document, such as the title of the page.
'<title>' sets the title appears in the browser's title bar or tab.
'<body>' contains the visible content of the web page.
'<h1>' represents a heading element, which defines the main heading on the page.
'<p>' represents a paragraph element, used for enclosing text paragraphs.
'<a>' represents an anchor element, used to create hyperlinks. The 'href' attribute specifies the URL that the link points to.

HTML provides a wide range of tags for organizing and formatting content, including headings, paragraphs, lists, tables, forms, images, and more. Each tag serves a specific purpose and has various attributes that can be used to customize its behavior and appearance.

In addition to HTML, Cascading Style Sheet (CSS) is often used to apply styles and layout to HTML elements, while JavaScript is used for adding interactivity and dynamic functionality to web pages.

HTML is a fundamental skill for web development, and understanding its syntax and structure is essential for creating and designing web pages. With HTML, you can create static websites or combine it with CSS and JavaScript to build interactive and dynamic web applications.

History of HTML:

HTML has a rich history that spans several decades. Here's a brief overviews of the major milestones and developments in the history of HTML:

1. Early Origins (1980s): The origins of HTML can be traced back to the early 1980s when researchers and scientists began exploring ways to share and hyperlink documents. The groundwork for HTML was laid by researchers such as Tim Berners-Lee, who proposed the concept of a "hypertext" system while working at CERN (Europeans Organization for Nuclear Research) in 1989.

2. HTML 1.0 (1991): In 1991, Tim Berners-Lee released the first version of HTML, known as HTML 1.0. It provided a basic set of tags for structuring and formatting documents. This version introduced elements such as headings, paragraphs, lists and links.

3. HTML 2.0 (1995): HTML 2.0 was released in 1995 and bought significant improvements to the language. It introduced new features like tables, image support, and basic form elements.

4. HTML 3.0 and 3.2 (1996-1997): HTML 3.0 was an ambitious but short-lived version that aimed to introduce advanced features like style sheets and scripting. However, due to limited features like style sheets and scripting. However, due to limited browser support, it was never widely adopted. HTML 3.2, released in 1997, provided a more practical set of features, including enhanced form controls and support for international characters.

5. HTML 4.0 and 4.01 (1997-1999): HTML 4.0, released in 1997, introduced a more modular approach to HTML. It includes features like frame sheets, which allowed the division of a web page into multiple sections, and the introduction of the document type declaration (DOCTYPE). HTML 4.01, released in 1999, was a minor update that fixed some issues and clarified certain aspects of the language.

6.XHTML (2000): XHTML (Extensible Hypertext Markup Language) was introduced in 2000 as an XML-based version of HTML. It aimed to bring the syntax of HTML into compliance with XML standards. XHTML 1.0 followed the structure for markup. XHTML 1.1 was released in 2001 as a more modular and extensible version.

7. HTML5 (2008-2014): HTML5 marked a significant milestone in the evolution of HTML. It was developed to address the increasing demand for rich multimedia content and interactive web applications. HTML5 introduced new elements like '<video>', '<audio>', and '<canvas>', along with improved semantics and accessibility features. It also included built-in support for multimedia playback, offline storage, and drag-and-drop functionality.

8. HTML Living Standard (2014-present): Instead of releasing new versions, HTML is now maintained as a "living standard". This means that the specification is continuously updated and improved. The WHATTWG (Web Hypertext Application Technology Working Group) takes the lead in maintaining the HTML Living Standard, with input from the broader web community.

The evolution of HTML has been driven by the need to support new technologies, improve functionality, and adapt to the changing demands of the web. HTML5 represents a major leap forward, providing developers with powerful tools for creating modern and dynamic we experiences.

Why Choose HTML Over Any Other Languages?

HTML is markup language specifically designed for creating the structure and content of web pages. While it has its specific purpose and is not intended for complex programming tasks, there are several reasons why you would choose HTML over other languages in certain contexts:

1. Web page structure: HTML excels at defining the structure and layout of web pages. It provides a range of elements for organizing content, such as headings, paragraphs, lists, tables, and forms. It your primary goal is to create and structure the content of web pages, HTML is the ideal choice.

2. Web development foundation: HTML is a fundamental language in web development. It serves as the foundation for building web pages and acts as the building block for other technologies like CSS (Cascading Style Sheets) for styling and JavaScript for interactivity. By learning HTML, you establish a solid foundation to understand and work with other web technologies effectively.

3. Accessibility and SEO: HTML provides semantic elements that help improve the accessibility and search optimization (SEO) of web pages. Semantic tags like '<header>', '<nav>', '<article>', and '<footer>' convey the structure and meaning of content to assistive technologies and search engine crawlers. This enhances the user experience for individuals with disabilities and improves the discoverability of web pages by search engines.

4. Compatibility and browser support: HTML enjoys broad compatibility and excellent support across different web browsers. It is a universally recognized and supported language, ensuring that your web pages will display correctly on most devices and platforms.

This simplicity makes HTML an excellent starting point for individuals new to web development.

6. Content creation ad editing: HTML is not limited to developers alone. Content creators, such as bloggers or individuals managing websites, can benefit from knowing HTML. It allows them to have more control over the structure and formatting of their content, making it easier to create and edit web pages according to their specific needs.

While HTML is an essential language for web development, it's important to note that it is typically used in conjunction with other languages and technologies like CSS and JavaScript. Each language serves its own purpose in the web development stack, and proficiency in multiple languages will enable you to create more dynamic and interactive web experience.

Features of HTML?

HTML, or Hypertext Markup Language, offers a wide range of features for creating and structuring web pages. Here are some key features of HTML:

1. Elements and Tags: HTML consists of a variety of elements and tags that define the structure and content of web pages. Elements like headings ('<h1>' to '<h6>'), paragraphs ('<p>'), lists ('<ul>', '<ol>', '<li>'), tables ('<table>', '<tr>', '<td>'), forms ('<form>', '<input>', '<textarea>'), and many more provide the building blocks for organizing and presenting content.

2. Semantic Markup: HTML offers sematic elements that give meaning and structure to web content. Semantic tags like '<header>', '<nav>', '<article>', '<section>', '<footer>', and '<aside>' help define the purpose and relationship of content, adding accessibility and search engine optimization.

3. Hyperlinks: HTML allows the creation of hyperlinks using the '<a>' (anchor) tag. Hyperlinks enable navigation within a web page or to other web pages, documents, or resources on the internet.

4. Images and Multimedia: HTML supports the embedding and display of images using the '<img>' tag. Additionally, HTML5 introduced elements like '<video>', '<audio>', and '<canvas>' to include multimedia content directly within web pages.

5. Forms and input Elements: HTML provides form elements ('<form>', '<input>', '<select>', '<textarea>', etc.) that allow users to input and submit data. Forms are essential for various user interactions, such as submitting forms, capturing user feedback, and collecting user information.

6. Attributes: HTML elements can have attribute that provide additional information or modify their behavior. Attributes such as 'class', 'id', 'src', 'href', and 'alt' are commonly used to specify styles, links, images, and alternative text.

7. Document Structure: HTML documents have a predefined structure that includes the '<html>', '<head>', and '<body>' tags. The '<head>' section contains meta-information about the document, such as the title, character encoding, and linked stylesheets or scripts. The '<body>' section contains the visible stylesheets or scripts. The '<body>' section contains the visible content of the web page.

8. Embedding Scripts: HTML allows the inclusion of scripts, primarily JavaScript, within web pages. Scripts enhance interactivity, dynamic behaviors, and data manipulation on web pages.

9. Semantic Metadata: HTML5 introduces semantic metadata elements like '<nav>', '<main>', '<section>', '<article>', and '<aside>', which help define the structure and semantics of the content, making it more meaningful for both humans and machines.

10. Mobile-Friendly Features: HTML5 introduces features like responsive images ('<picture>', '<source>'), media queries, and the viewport meta tag ('<meta name="viewport">') that enable web pages to adapt to different screen sizes and provide a better user experience in mobile devices.

These are just a few many features that HTML offers. Combined with CSS for styling and JavaScript for interactivity, HTML forms the foundation for creating dynamic, visually appealing, and interactive web pages and web applications.

Applications of HTML?

The scope of HTML according to us is always limited to the creation of webpages using HTML, however, there are a lot more. Here, in this article, we have analyzed the various applications of HTML, the new features of HTML5 which support advanced web developments, and listed down the Users of HTML on the Real World.

1. Web Pages Development: Different websites we see no the internet regularly are in some form written in HTML code. As mentioned earlier HTML is used to structure the web pages in various ways. We could include different sections, insert tables, and split the web page. With the introduction of Semantic HTML elements in HTML5, HTML has made hassle free even for the developer to understand and modify his/her code better.

Apart from the elements, we can style different types of web pages like the landing page, parallax pages, grid orientation pages, etc. Styling and manipulation of HTML elements are comparatively easier and more effective with CSS and JavaScript.

2. Navigating the Internet: HTML is an essential elements in navigation between web pages. Navigation is possible using the hypertext concept. The linking is also simpler From the internet user's point of view, they click on a text which takes them to the next page. HTML facilities navigation by hyperlinking with the help of an anchor tag.

<a href="google.com"> Click here to open! </a>

Navigation can increase visitors to a website. It increase user activity on the website. It also helps the web user to look at the content structure and organization.

3. Responsive Designs: The integral part of a web page is for it to be interactive and responsive to the user. HTML makes is possible. Unlike static pages, responsive ones also have a better reach. Automatically resizing, hiding, shrinking, or enlarging a website to make it look good on all devices (desktops, tablets, and phones) is what a responsive web design is made of where HTML and CSS aid the purpose.

4. Storage Function in the Browser: Storage of data in the browser was tedious in the past. For a user to save the data of the browser that persists between two sessions, the user's cookies or infrastructure is to be build from the server end. This process has now been eased with HTML5. HTML5 has roped in new features. Such storage features are localStorage and IndexDB.

The web storage objects window.localStorage and window.sessionStorage store data with no expiration date and storage for one session respectively. The localStorage object will have the data saved even when the browser is closed. setltem and removeltem are the functions commonly used to store and remove data from the storage. Also, the most important part is that these features are supported by all browsers.

To Store - localStorage.setltem("username", "Dev");
To Retrieve - document.getElementById("result").innerHTML = localStorage.getItem("username");
To Remove - localStorage.removeItem("username");

5. Data Entry Support: With many other features that we have been discussing, here's another important one to be takes into account which is data entry. For so long we have stored data in dedicated files for this purpose. HTML5 paves way for data entry online, that is to obtain the data to store, from the user via forms. In this case, we have HTML tags like <form>.

Other elements include input which may be a drop-down box, list, text box, password box, etc. On the whole, HTML makes the process of data entry easy and effective which also include validation with the help of JavaScript.

6. Creation of Web Documents: HTML is predominantly used in creating web document on the internet. DOM (Document Object Model) is used in the creation of web documents. In addition, HTML tags are used in formatting the document. The HTML web document begins with the declaration of <!DOCTYPE html>. Further, it proceeds with the usual HTML opening and closing tags. The HTML DOM model is constructed as a tree of objects.

The root element is the <html> which is divided into head and body. The Head contains the title of the page or document. The body consists of the content which is built using various elements such as heading, paragraphs, line breaks, anchors, etc. Further down the tree is the attributes of the elements. For instance, anchor tag <a> has an attribute say, 'href'.

7. Game Development: We see in recent days, from kids, and teens to adults all of them are drowned in online games. Let us get to know the role of HTML in the creation of such games. Earlier game developments were specific to platforms like Flash. However, HTML5 offers many options and features for game development. Beginners can start with HTML elements such as canvas which offers all the functionality needed for making games.

To create a canvas:

To draw inside the canvas:

var c = document.getElementById("canvas");

var ctx = c.getContext("2d");

ctx.moveTo(0, 0);

ctx.LineTo(200, 100);

ctx.stroke();

</script>

JavaScript could be used to draw, insert images, write, etc. into the canvas. CSS3 is an advanced version of Cascading Style Sheet used in structuring, styling, and formatting. Various components, controllers, etc. are added making the game lively. Thus, it is not longer a big deal to develop games.

8 Offline Web Applications: We know, it is always necessary to have internet connectivity to view web pages. However, nowadays web applications could be accessed even when we are offline. The user will be able to access the data with the help of HTML. It uses a cache manifest file to determine which data to store while offline.

In case you are traveling outside you Interner Service Provider's Coverage Area, your connection is likely no more available. In this case, the user provides a manifest that lists the files which are needed for a web application to work offline. This causes the user's browser to have a copy of the files for offline use.

9. Cutting Edge Feature: Cutting-edge is often used to describe disruptive technologies as well as the largest technological advancements. As we have looked so far, HTMl5 has brought in many changes and advancements in web development. Cutting-edge web design trends include animated HTML headers, embeddable infographics, designing around illustrations with CSS, scroll-triggered call-to-action, user badges, etc.

Google Chrome serves to be an excellent choice for browser for the use of HTML's recent set of standards and APIs. It lets the libraries download the required packages dynamically whenever required.

10. Enrich the Website: HTML allows the use of Native APIs to enrich the website. With the many features that HTMl5 has introduced, it has also introduced many tools and capabilities that were never expected before. APIs like visibility, full screen, and media capture could be used to improve the experience of applications.

The APIs effectively allows us to do the background work independently of other UI scripts, without affecting the performance of the page. The major role of these APIs is to create custom controls and functions.

There are just a few examples of the diverse applications of HTML. HTML's versatility, simplicity, and wide adoption make it an essential language for various web-related tasks and content creation.
