HTML Block and Inline Elements


Every HTML element has a default display value, depending on what type of element it is.
There are two display values: block and inline.


Block-level Elements

A block-level element always starts on a new line, and the browsers automatically add some space (a margin) before and after the element.
A block-level element always takes up the full width available (stretches out to the left and right as far as it can).
Two commonly used block elements are: <p> and <div>.
The <p> element defines a paragraph in an HTML document.
The <div> element defines a division or a section in an HTML document.

The <p> element is a block-level element.

The <div> element is a block-level element.

Example:

<p>Hello World</p>
<div>Hello World</div>

Here are the block-level elements in HTML:

<address> <article> <aside> <blockquote>
<canvas> <dd> <div> <dl>
<dt> <fieldset> <figcaption> <figure>
<footer> <form> <h1>-<h6> <header>
<hr> <li> <main> <nav>
<nonscript> <ol> <p> <pre>
<section> <table> <tfoot> <ul>
<video>

An inline element does not start on a new line.
An inline element only takes up as much width as necessary.
This is a <span> element inside a paragraph.

Example:

<span>Hello World</span>

Here are the inline elements in HTML:

<a> <abbr> <acronym> <b>
<bdo> <big> <br> <button>
<cite> <code> <dfn> <em>
<i> <img> <input>-<h6> <kbd>
<label> <map> <object> <output>
<q> <samp> <script> <select>
<small> <span> <strong> <sub>
<sup> <textarea> <time> <tt>
<var>

Note: An inline element cannot contain a block-level element!


The <div> Element

The <div> element is often used as a container for other HTML elements.
The <div> element has no required attributes, but style, class and id are common.
When used together with CSS, the <div> element can be used to style blocks of content:

Example:

<div style="background-color: black; color: white; padding: 20px;"
    <h2>London</h2>
    <p>London is the capital city of England. It is the most populous city in the United Kingdom, with a metropolitan area of over 13 million inhabitants.</p>
</div>

The <span> Element

The <span> element is an inline container used to mark up a part of a text, or a part of a document.
The <span> element has no required attributes, but style, class and id are common.
When used together with CSS, the <span> element can be used to style parts of the text:

Example:

<p>My mother has <span style=""color: blue; font-weight: bold;>blue </span> eyes and my father has <span style=color: drakolivegreen; font-weight: bold;">dark green </span>eyes.</p>
