Introduction

If you ever opened an HTML file and saw angle brackets < > everywhere, you’ve already seen HTML tags.

But, tags alone don't build websites — it’s the combination of tags, elements, and attributes that shapes a fully functional web page.

Before diving deeper into HTML development, you need a crystal-clear understanding of:

  • What are Tags?
  • What are Elements?
  • What are Attributes?

These concepts form the language of HTML — and mastering them will make everything else in web development much easier.

1. What is an HTML Tag?

Definition:

An HTML tag is a keyword surrounded by angle brackets < >, which tells the browser how to display or structure content.

Syntax Example:

This is a paragraph.

  •  is an opening tag.
  • is a closing tag.

Important Notes:

  • Most tags come in pairs (opening and closing).
  • Some tags are self-closing (more on that later).

Think of a tag as a label you put on content — like tagging a box as "Fragile" or "Electronics" to indicate how it should be handled.

2. What is an HTML Element?

Definition:

An HTML element is everything from the start tag to the end tag, including the content between them.

Example:

Welcome to My Website

Here:

  •  = Opening tag
  • Welcome to My Website = Content
  • = Closing tag

Together, this entire structure is called an HTML Element.

Visual Breakdown:

Welcome... Content

Element Combination of all above

Key Takeaway:

While tags describe what something is, elements are the complete units of meaning.

3. What are HTML Attributes?

Definition:

An attribute provides additional information about an HTML element.

It modifies or clarifies the behavior or appearance of the element.

Syntax:

attribute="value">Content

Example:

href="https://thecampuscoders.com">Visit The Campus Coders
  • = Anchor tag (used for links)
  • href="https://thecampuscoders.com" = Attribute
  • "https://thecampuscoders.com" = Value assigned to the href attribute
  • Visit The Campus Coders = Link text

Commonly Used Attributes:

Attribute Purpose
href Specifies the URL for a link
src Specifies the path for an image ()
alt Alternative text for images (important for SEO)
id Unique identifier for an element
class Defines CSS class(es)
style Adds inline CSS styling
title Tooltip text on hover
target Specifies where to open the linked document

Best Practice:

Always write attributes in lowercase, and always enclose values inside double quotes (" ").
