Syntax Structure of an HTML Element

Inline Elements

By default, inline elements appear next to one another in a webpage. They take up only as much width as they need in a page and fit together horizontally like words in a sentence or books shelved side-by-side in a row.

Usage	Tag	Example
📦 Inline Container	<span>	Used to group parts of text, often for styling: <span class="purple"> Styled text </span>
Emphasized Text	<em>	<em> I am in italics </em>
Important Text	<strong>	<strong> I am bold! </strong>
🔗 Link	<a>	<a href="https://example.org"> Go somewhere </a>
🖼️ Image	<img>	Self-closing tag, but the src attribute is required: <img src="profile-pic.png" width="50px">

Block Elements

Block elements, on the other hand, take up the entire width of a webpage by default. They also take up a full line of a webpage; they do not fit together side-by-side. Instead, they stack like paragraphs in an essay or toy blocks in a tower.

Usage	Tag	Example
📦 Block Container	<div>	Used to group elements for organization/layout: <div id="section-1"> </div>
💬 Paragraph Text	<p>	<p> I am a paragraph of text. </p>
📣 Heading Text	<h1>…<h6>	<h1> Primary heading </h1> <h2> Secondary heading </h2> …
➖ Horizontal Rule	<hr>	Self-closing tag, just insert <hr> anywhere for a break with a border line
↩ Line Break	<br>	Self-closing tag, just insert <br> anywhere for a blank space break

Inline elements are usually nested inside block elements:

<p>
  This is a paragraph block with some inline elements
  like <strong>bold words</strong> or maybe even a
  <a href="www.somewebsite.com">link</a>!
