Introduction
HTML (Hypertext Markup Language) is the standard markup language used to create web pages. It is used as a document declaration that instructs the browser about the version of HTML. In this article, we will discuss the basic structure of an HTML document and the attributes of HTML tags.
HTML Document Declaration
- HTML is used as a document declaration that instructs the browser about the version of HTML. The first line of an HTML document is the document declaration, which is used to declare the version of HTML being used. This line is also known as the DOCTYPE declaration. The DOCTYPE declaration is used to tell the browser which version of HTML is being used and to validate the document.
<!DOCTYPE html>
The DOCTYPE declaration is case-insensitive, but it is recommended to use the uppercase version.
HTML Tag Structure
- Every tag consists of two parts: name and value. An HTML tag consists of two parts: the name and the value. The name of the tag is the name of the element, and the value is the content of the element.
<tagname>value</tagname>
For example, the <p>
tag is used to create a paragraph of text. The name of the tag is p
, and the value is the text that is contained within the tag.
<p>This is a paragraph of text.</p>
Tag Attributes
HTML tags can also have attributes, which are used to provide additional information about the tag. Attributes are used to specify the characteristics of the tag, such as the color of the text or the size of the font.
<tagname attribute="value">value</tagname>
For example, the <p>
tag can have an attribute called style
, which is used to specify the style of the text.
<p style="color: blue;">This is a paragraph of text.</p>
Tag Nesting
- The possibility of opening a new tag before closing the previous tag is known as tag nesting. Tag nesting is the process of opening a new tag before closing the previous tag. This is a common practice in HTML, and it is used to create complex document structures.
<tagname>value
<tagname>value</tagname>
</tagname>
For example, the following code creates a paragraph of text that contains a heading:
<p>This is a paragraph of text.
<h2>This is a heading.</h2>
</p>
Closing Tags
It is essential to close all tags in an HTML document. Closing tags are used to indicate the end of a tag. Closing tags are identical to opening tags, except that they have a /
symbol at the beginning.
</tagname>
For example, the following code creates a paragraph of text that contains a heading:
<p>This is a paragraph of text.
<h2>This is a heading.</h2>
</p>
HTML Document Structure
An HTML document consists of several parts, including the document declaration, the head section, and the body section.
<!DOCTYPE html>
<html>
<head>
<!-- head section -->
</head>
<body>
<!-- body section -->
</body>
</html>
The head section contains metadata about the document, such as the title of the page and the character encoding.
<head>
<title>Document Title</title>
<meta charset="UTF-8">
</head>
The body section contains the content of the document, such as text, images, and links.
<body>
<h1>Document Title</h1>
<p>This is a paragraph of text.</p>
</body>

property is used to specify the visibility of an element. The display
property is used to change the layout of the document, while the visibility
property is used to change the visibility of an element.
