HTML Elements

An HTML element usually consists of a start tag and end tag, with the content inserted in
between:

<tagname>Content goes here...</tagname>


The HTML element is everything from the start tag to the end tag:

<p>My first paragraph.</p>

Start tag Element content End tag


<h1> My First Heading </h1>
<p> My first paragraph. </p>
<br>

HTML elements with no content are called empty elements. Empty elements do not have
an end tag, such as the <br> element (which indicates a line break).

HTML Attributes

The lang Attribute

The language of the document can be declared in the <html> tag.


The language is declared with the lang attribute.
Declaring a language is important for accessibility applications (screen readers) and search
engines.
<html lang="en-US">
