Learn HTML HTML Elements

An HTML element is the fundamental building block of an HTML document.

An element usually consists of

A start tag
Content
An end tag

The browser reads elements to understand how content should be structured and displayed.

Basic Structure of an HTML Element

An HTML element is written using angle brackets.

In this example <p> is the start tag This is a paragraph is the content </p> is the end tag

Together they form one complete HTML element.

Parts of an HTML Element

Part	Description
Start tag	Marks the beginning of the element
Content	Text or nested elements inside
End tag	Marks the end of the element

Not all elements contain all three parts.

Nested HTML Elements

HTML elements can contain other elements inside them.

This is called nesting.

Here <h2> and <p> are nested inside <div>

Proper nesting is required for correct page structure.

HTML Empty Elements

Some HTML elements do not have closing tags.

These are called empty elements.

Empty elements do not contain content.

Common Empty Elements

Element	Purpose
`<br>`	Line break
`<img>`	Displays an image
`<hr>`	Horizontal line
`<input>`	User input field

Empty elements rely entirely on attributes.

Block Level Elements

Block level elements start on a new line.

Common Block Level Elements

Element	Description
`<div>`	Generic container
`<p>`	Paragraph
`<h1>` to `<h6>`	Headings
`<section>`	Page section
`<article>`	Independent content

Block elements are used for layout and structure.

Inline Elements

Inline elements do not start on a new line.

They take only as much width as needed.

Common Inline Elements

Element	Description
`<span>`	Inline container
`<a>`	Link
`<strong>`	Strong importance
`<em>`	Emphasized text
`<img>`	Inline image

Inline elements are used inside block elements.

Attributes are written inside the start tag.
