HTML Block and Inline Elements

作者: 春暖花开奇奇乐乐 | 来源:发表于2018-07-06 15:29 被阅读11次

Every HTML element has a default display value depending on what type of element it is. The default display value for most elements is block or inline.

Block-level Elements
A block-level element always starts on a new line and takes up the full width available (stretches out to the left and right as far as it can).

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

<!DOCTYPE html>
<html>
<body>

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

<p>The DIV element is a block element, and will start on a new line.</p>

</body>
</html>

Block level elements in HTML:

<address>

<article>

<aside>

<blockquote>

<canvas>

<dd>

<div>

<dl>

<dt>

<fieldset>

<figcaption>

<figure>

<footer>

<form>

<h1>-<h6>

<header>


<li>

<main>

<nav>

<noscript>

<ol>

<output>

<p>

<pre>

<section>

<table>

<tfoot>

<ul>

<video>

Inline Elements

An inline element does not start on a new line and only takes up as much width as necessary.

This is an inline <span> element inside a paragraph.

<!DOCTYPE html>
<html>
<body>

<span>Hello</span>
<span>World</span>

<p>The SPAN element is an inline element, and will not start on a new line.</p>

</body>
</html>

Inline elements in HTML:

<a>

<abbr>

<acronym>

<b>

<bdo>

<big>


<button>

<cite>

<code>

<dfn>

<em>

<i>

<img>

<input>

<kbd>

<label>

<map>

<object>

<q>

<samp>

<script>

<select>

<small>

<span>

<strong>

<textarea>

<time>

<tt>

<var>

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:

<!DOCTYPE html>
<html>
<body>

<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>
  <p>Standing on the River Thames, London has been a major settlement for two millennia, its history going back to its founding by the Romans, who named it Londinium.</p>
</div> 

</body>
</html>

The <span> Element

The <span> element is often used as a container for some text.

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:

<!DOCTYPE html>
<html>
<body>

<h1>My <span style="color:red">Important</span> Heading</h1>

</body>
</html>

HTML Grouping Tags

Tag Description
<div> Defines a section in a document (block-level)
<span> Defines a section in a document (inline)
