Introduction
The HTML tag serves as the foundation of an HTML or XHTML document, signaling to the browser that the content is in HTML format. Positioned as the outermost container after the initial declaration, it encapsulates all subsequent content within an HTML file. Both the opening and closing tags are crucial for the proper functioning of the HTML tag.
What is HTML?
Hypertext Markup Language, commonly known as HTML, serves as a fundamental markup language extensively employed in the development of web pages, websites, and web applications. The inception of HTML dates back to 1990 when it was first proposed by Tim Berners-Lee, with its formal recommendation by W3C occurring in 2014.
HTML is the language used to create web pages, utilizing a combination of plain text and tags to provide structure and instructions to web browsers on how to present the content. Tags in HTML serve the purpose of identifying page elements like lists, headings, paragraphs, links, as well as different types of media and images.
HTML elements can either be void or contain two tags that enclose content within them. A void element, denoted by an opening <> and closing </> tags, is the most common type of HTML tag. It is also referred to as an element or an HTML element. For example:
<html>
</html>
What is the Root Element of an HTML Document?
The HTML element serves as the foundational element of an HTML document, initiating the parsing process and encompassing all other document components.
The HTML element's head and body components are required to be nested within it as child elements.
The content within the body element comprises text and images, while essential information like the title, meta tags, and scripts are located in the head element.
Every HTML element should be enclosed within an opening tag and a closing tag that follow these guidelines:
<html>?</html> ? Starts with <html>, ends with </html>.
<head>?</head> ? Starts with <head>, ends with </head>.
<body>?</body> ? Starts with <body>, ends with </body>.
An HTML element is allowed to be void if it doesn't require any essential metadata or content.
Example
<html>
<head>
<title>

</title>
</head>
<body style="text-align: center;">
<h1 style="color: blue;">

<p>
Example
</p>
</body>
</html>
Output
The head section of an HTML document holds crucial information such as metadata, stylesheets, scripts, character encoding, title, and various other elements.
Apart from the main title known as the HTML document title, there is supplementary metadata included. An effective title, brief yet descriptive, plays a crucial role in summarizing the content of the page. This title can be displayed in various places such as search engine results, the tab of the browser, or the title bar of the window.
Moreover, the head section contains essential information about the document, such as the character encoding, the stylesheets applied, and the scripts utilized for interactivity within the document.
The element holds the content of a document or application. It serves as a container for various objects, including text and graphics, that are visible within a web browser along with other displayed elements.
The body element in HTML is responsible for containing the main content of a web page. It is utilized by CSS to style the header, footer, and other elements that make up the content of the webpage.
A webpage's Element serves as a wrapper for all other elements within it. All content, such as text and images, should be enclosed within the "body" section of your HTML page. While every HTML document contains a body section, it is possible for it to have no content inside.
The main container for all components within an HTML document should be unique and identifiable. This container element should have a single child, which must always be another element.
An illustration showcasing the utilization of the tag is provided in the following example:
<html>
<head>
</head>
<body>
First line <br/> second line <br/> third line <br/> fourth line <br/>
</body>
</html>
Output
Web developers use doctype declarations to communicate the structure of their HTML documents to modern browsers.
The doctype declaration must be placed before the root element in an HTML page.
Validating an HTML document solely based on the doctype declaration is not recommended. This is due to the possibility of a webpage containing incorrect HTML code but still passing a validator that conforms to W3C standards. For example, the absence of an alt attribute in an <a> element or a missing <img> tag can lead to accessibility problems, even though these issues may not be identified by the W3C validator.
<html>
<head>
<title>Example</title>
</head>
<body>
<h1>Heading</h1>

Output
The root of an HTML document is '<html>' . It acts as a bigger container element that contains the rest of the elements and gives the page a strong structure. This concept of the document structure is the first one to be outlined and it explicitly contains elements like '<head> and '<body>' sections. The root element encloses all the content and information of the webpage and is rendered by web browsers using its functions to create the page. It defines the vertical context of HTML documents and ensures proper organization and presentation of the data on various platforms and gadgets. Hence, the root element is the key element in effective web development and design.
