Understanding Tags in HTML

What are HTML Tags?

HTML (HyperText Markup Language) is the standard markup language used to create web pages. Tags are the building blocks of HTML, used to describe the structure and content of the page.

Structure of HTML Tags

HTML tags are composed of elements enclosed in angle brackets, for example: <tagname>.... Most tags come in pairs: an opening tag and a closing tag, where the closing tag includes a forward slash, like this: </tagname>.

Example of Tags


<h1>This is a Heading</h1>
<p>This is a paragraph.</p>
<a href="https://www.example.com">This is a link</a>

Common HTML Tags

<html>: The root element that wraps all the content on the web page.
<head>: Contains meta-information about the document, such as title and links to stylesheets.
<title>: Specifies the title of the web page, which appears in the browser tab.
<body>: Represents the content of the web page, including text, images, and more.
<p>: Defines a paragraph.
<a>: Defines a hyperlink.
<img>: Embeds an image in the document.
<div>: A generic container for grouping content.

Self-Contained Tags

Some HTML tags do not require a closing tag and are hence referred to as void or self-contained tags. Examples include:

<br>: Inserts a line break.
<hr>: Represents a thematic change in the context of the content.
<img>: Embeds an image. It requires attributes like src for the image source to be functional.

Attributes in HTML Tags

HTML tags can have attributes that provide additional information about the element. Attributes are always included in the opening tag and appear as name-value pairs:

<a href="https://www.example.com">Visit Example</a>

In the above example, href is an attribute of the <a> tag, indicating the URL the link points to.

Conclusion

Understanding HTML tags is essential for anyone looking to create, manage, or participate in web development. They provide the structure and format for content on the web, allowing developers to deliver a rich user experience.
