When creating web pages using HTML, two foundational concepts you must understand are HTML elements and HTML tags. These are the building blocks of every webpage, and knowing how to use them properly is essential for writing clean, functional HTML.
An HTML tag is a code snippet used to mark up content in an HTML document. Tags are used to define elements, such as headings, paragraphs, links, images, and more.
A tag is usually written inside angle brackets like this:
<p>This is a paragraph.</p>
Most tags come in pairs, but some self-closing tags do not require an end tag (e.g., <br>, <img>, <hr>).
An HTML element consists of:
For example:
<h1>Hello, World!</h1>
This entire line is an HTML element:
There are two main types of elements:
1. Block-Level Elements
These elements take up the full width of the page and start on a new line.
Examples:
<h1>, <p>, <div>, <section>, <article>, <ul>, <ol>, <li>
2. Inline Elements
These elements do not start on a new line and only take up as much width as necessary.
Examples:
<span>, <a>, <strong>, <em>, <img>, <br>
Some elements don't have any content or closing tag. These are called void or self-closing elements.
Examples:
<img src="image.jpg" alt="Image description"> <br> <hr> <meta charset="UTF-8">
HTML elements can be nested inside each other, but they must be properly closed in the correct order.
Correct nesting:
<p>This is <strong>bold</strong> text inside a paragraph.</p>
Incorrect nesting:
<p>This is <strong>bold text</p></strong> <!-- ❌ Not correct -->
HTML elements and tags form the very foundation of web development. Every visible part of a webpage is built using these components. Understanding how to use them correctly is the first step toward creating well-structured web pages.
