HTML: Hypertext Markup Language

HTML is a markup language used to create content for the world wide web. HTML is short for Hypertext Markup Language. It is a language for creating structured and semantic web documents. HTML is used to create everything from simple static web pages to complex web applications.

Purpose of HTML

HTML is a language that is used to structure content on the web. It allows developers to create web pages and web applications that are organized, easy to read, and semantically meaningful. HTML provides a set of tags that are used to define the structure and content of web pages.

Usage of HTML

HTML is used to create everything from simple web pages to complex web applications. It is at the core of every website and web application. HTML provides a set of tags that are used to define the structure and content of web pages. These tags are used to create headings, paragraphs, lists, tables, forms, and much more.

HTML is a language that is easy to learn and use. It can be used by anyone who wants to create web pages or web applications. HTML is a standard language that is implemented by all web browsers. This means that web pages and web applications created with HTML can be viewed on any device with a web browser.

Structure of HTML

HTML documents are composed of a structure of tags. These tags are used to define the structure and content of web pages. HTML tags are enclosed in angle brackets and consist of three parts:

• The opening tag
• The content
• The closing tag

The opening tag is used to tell the browser what type of tag it is. The content is the actual content of the tag. The closing tag is used to tell the browser when the tag ends.

Here is an example of an HTML tag:

<p>This is a paragraph tag.</p>

As you can see, the opening tag is <p>, the content is “This is a paragraph tag.”, and the closing tag is </p>.

Elements of HTML

HTML elements are the building blocks of HTML documents. An HTML element is defined by a start tag, some content, and an end tag. Here is an example of an HTML element:

<h1>Welcome to my website!</h1>

In this example, the <h1> tag is the start tag, “Welcome to my website!” is the content, and </h1> is the end tag.

HTML elements can be nested inside other elements. This allows developers to create complex structures for web pages and web applications.

Attributes of HTML

HTML attributes are used to provide additional information about an HTML element. Attributes are added to the opening tag of an HTML element. Here is an example of an HTML element with an attribute:

<img src="image.png" alt="An image of a cat.">

In this example, the src attribute is used to specify the location of the image file, and the alt attribute is used to provide a description of the image.

Semantic HTML

Semantic HTML is a way of writing HTML that provides additional meaning to the content of web pages and web applications. It is a way of writing HTML that is focused on content, rather than presentation.

Semantic HTML uses HTML tags that have a specific meaning. For example, the <h1> tag is used for headings, the <p> tag is used for paragraphs, and the <ul> and <ol> tags are used for lists. By using these tags, developers can create web pages and web applications that are more accessible and easier to understand.
