Introduction to HTML

What is an HTML File?

  • HTML stands for Hyper Text Markup Language
  • An HTML file is a text file containing small markup tags
  • The markup tags tell the Web browser how to display the page
  • An HTML file must have an htm or html file extension
  • An HTML file can be created using a simple text editor

Do You Want to Try It?

If you are running Windows, start Notepad.

If you are on a Mac, start SimpleText.

In OSX start TextEdit and change the following preferences: Open the the "Format" menu and select "Plain text" instead of "Rich text". Then open the "Preferences" window under the "Text Edit" menu and select "Ignore rich text commands in HTML files". Your HTML code will probably not work if you do not change the preferences above!

Type in the following text:



Title of page


This is my first homepage. This text is bold

Save the file as "mypage.htm".

Start your Internet browser. Select "Open" (or "Open Page") in the File menu of your browser. A dialog box will appear. Select "Browse" (or "Choose File") and locate the HTML file you just created - "mypage.htm" - select it and click "Open". Now you should see an address in the dialog box, for example "C:\MyDocuments\mypage.htm". Click OK, and the browser will display the page.

Example Explained

The first tag in your HTML document is . This tag tells your browser that this is the start of an HTML document. The last tag in your document is . This tag tells your browser that this is the end of the HTML document.

The text between the tag and the tag is header information. Header information is not displayed in the browser window.

The text between the tags is the title of your document. The title is displayed in your browser's caption.</p> <p>The text between the <body> tags is the text that will be displayed in your browser.</p> <p>The text between the <b> and </b> tags will be displayed in a bold font.</p> <hr /> <h2>HTM or HTML Extension?</h2> <p>When you save an HTML file, you can use either the .htm or the .html extension. We have used .htm in our examples. It might be a bad habit inherited from the past when some of the commonly used software only allowed three letter extensions.</p> <p>With newer software we think it will be perfectly safe to use .html.</p> <hr /> <h2>Note on HTML Editors:</h2> <p>You can easily edit HTML files using a WYSIWYG (what you see is what you get) editor like FrontPage or Dreamweaver, instead of writing your markup tags in a plain text file.</p> <p>However, if you want to be a skillful Web developer, we strongly recommend that you use a plain text editor to learn your primer HTML.</p> <hr /> <h2>Frequently Asked Questions</h2> <p><b>Q: After I have edited an HTML file, I cannot view the result in my browser. Why?<br />A: </b>Make sure that you have saved the file with a proper name and extension like "c:\mypage.htm". Also make sure that you use the same name when you open the file in your browser. </p> <p><b>Q: I have edited an HTML file, but the changes don't show in the browser. Why?<br />A: </b>A browser caches pages so it doesn't have to read the same page twice. When you have modified a page, the browser doesn't know that. Use the browser's refresh/reload button to force the browser to reload the page. </p> <p><b>Q: What browser should I use?<br />A: </b>You can do all the training with all of the well-known browsers, like Internet Explorer, Firefox, Netscape, or Opera. However, some of the examples in our advanced classes require the latest versions of the browsers.</p> <p><b>Q: Does my computer have to run Windows? What about a Mac?<br />A: </b>You can do all your training on a non-Windows computer like a Mac.</p><p class="intro">HTML documents are text files made up of HTML elements.</p> <p class="intro">HTML elements are defined using HTML tags.</p> <hr /> <h2>HTML Tags</h2> <ul><li>HTML tags are used to mark-up HTML <b> elements</b></li><li>HTML tags are surrounded by the <b> two characters <></b></li><li>The surrounding characters are called <b>angle brackets</b></li><li>HTML tags normally <b> come in pairs</b> like <b> and </b></li><li>The first tag in a pair is the <b> start tag,</b> the second tag is the <b> end tag</b></li><li>The text between the start and end tags is the <b>element content</b></li><li>HTML tags are <b> not case sensitive,</b> <b> means the same as <b></li></ul> <hr /> <h2>HTML Elements</h2> <p>Remember the HTML example from the previous page:</p> <table class="ex" border="1" cellspacing="0" width="100%"><tbody><tr><td> <pre><html><br /><head><br /><title>Title of page


This is my first homepage. This text is bold

This is an HTML element:

This text is bold

The HTML element starts with a start tag:
The content of the HTML element is: This text is bold
The HTML element ends with an end tag:

The purpose of the tag is to define an HTML element that should be displayed as bold.

This is also an HTML element:


This is my first homepage. This text is bold

This HTML element starts with the start tag , and ends with the end tag .

The purpose of the tag is to define the HTML element that contains the body of the HTML document.

Why do We Use Lowercase Tags?

We have just said that HTML tags are not case sensitive: means the same as . If you surf the Web, you will notice that plenty of web sites use uppercase HTML tags in their source code. We always use lowercase tags. Why?

If you want to follow the latest web standards, you should always use lowercase tags. The World Wide Web Consortium (W3C) recommends lowercase tags in their HTML 4 recommendation, and XHTML (the next generation HTML) demands lowercase tags.

Tag Attributes

Tags can have attributes. Attributes provide additional information to an HTML element.

The following tag defines an HTML table:

. With an added border attribute, you can tell the browser that the table should have no borders:

Attributes always come in name/value pairs like this: name="value".

Attributes are always specified in the start tag of an HTML element.

Attributes and attribute values are also case-insensitive. However, the World Wide Web Consortium (W3C) recommends lowercase attributes/attribute values in their HTML 4 recommendation, and XHTML demands lowercase attributes/attribute values.

Always Quote Attribute Values

Attribute values should always be enclosed in quotes. Double style quotes are the most common, but single style quotes are also allowed.

In some rare situations, like when the attribute value itself contains quotes, it is necessary to use single quotes:

name='John "ShotGun" Nelson'

The most important tags in HTML are tags that define headings, paragraphs and line breaks.

The best way to learn HTML is to work with examples. We have created a very nice HTML editor for you. With this editor, you can edit the HTML source code if you like, and click on a test button to view the result.

Try it Yourself - Examples

A very simple HTML document
This example is a very simple HTML document, with only a minimum of HTML tags. It demonstrates how the text inside a body element is displayed in the browser.

Simple paragraphs
This example demonstrates how the text inside paragraph elements is displayed in the browser.

(You can find more examples at the bottom of this page)

Headings

Headings are defined with the

to

tags.

defines the largest heading.

defines the smallest heading.

This is a heading

This is a heading

This is a heading

This is a heading

This is a heading

This is a heading

HTML automatically adds an extra blank line before and after a heading.

Paragraphs

Paragraphs are defined with the

tag.

This is a paragraph

This is another paragraph

HTML automatically adds an extra blank line before and after a paragraph.

Line Breaks

The
tag is used when you want to end a line, but don't want to start a new paragraph. The
tag forces a line break wherever you place it.

This 
 is a para
graph with line breaks

The
tag is an empty tag. It has no closing tag.

Comments in HTML

The comment tag is used to insert a comment in the HTML source code. A comment will be ignored by the browser. You can use comments to explain your code, which can help you when you edit the source code at a later date.

Note that you need an exclamation point after the opening bracket, but not before the closing bracket.

Basic Notes - Useful Tips

When you write HTML text, you can never be sure how the text is displayed in another browser. Some people have large computer displays, some have small. The text will be reformatted every time the user resizes his window. Never try to format the text in your editor by adding empty lines and spaces to the text.

HTML will truncate the spaces in your text. Any number of spaces count as one. Some extra information: In HTML a new line counts as one space.

Using empty paragraphs

to insert blank lines is a bad habit. Use the
tag instead. (But don't use the
tag to create lists. Wait until you have learned about HTML lists.)

You might have noticed that paragraphs can be written without the closing tag

. Don't rely on it. The next version of HTML will not allow you to skip ANY closing tags.

HTML automatically adds an extra blank line before and after some elements, like before and after a paragraph, and before and after a heading.

We use a horizontal rule (the

tag), to separate the sections in our tutorials.

Basic HTML Tags

Tag Description
Defines an HTML document
Defines the document's body

to

Defines header 1 to header 6

Defines a paragraph

Inserts a single line break
Defines a horizontal rule
Defines a comment

HTML defines a lot of elements for formatting output, like bold or italic text.

Below are a lot of examples that you can try out yourself:

html text format:-





This text is bold





This text is strong






This text is big






This text is emphasized






This text is italic






This text is small





This text contains

subscript





This text contains

superscript





Preformatted text





This is
preformatted text.
It preserves      both spaces
and line breaks.


The pre tag is good for displaying computer code:




for i = 1 to 10
     print i
next i






This is
preformatted text.
It preserves      both spaces
and line breaks.

The title attribute is used to show the spelled-out version when holding the mouse pointer over the acronym or abbreviation.


This only works for the acronym element in IE 5.


This works for both the abbr and acronym element in Netscape 6.2.

quations:-




Here comes a long quotation:

This is a long quotation. This is a long quotation. This is a long quotation. This is a long quotation. This is a long quotation.


Here comes a short quotation:

This is a short quotation



With the block quote element, the browser inserts line breaks and margins, but the q element does not render as anything special.

Most browsers will overstrike deleted text and underline inserted text.




Some older browsers will display deleted or inserted text as plain text.






a dozen is twenty twelve pieces

Most browsers will overstrike deleted text and underline inserted text.

Some older browsers will display deleted or inserted text as plain text.

How to View HTML Source

Have you ever seen a Web page and wondered "Hey! How did they do that?"

To find out, click the VIEW option in your browser's toolbar and select SOURCE or PAGE SOURCE. This will open a window that shows you the HTML code of the page.

When using named anchors we can create links that can jump directly into a specific section on a page, instead of letting the user scroll around to find what he/she is looking for.<br /><br />Below is the syntax of a named anchor:<br /><br /><a name="label">Text to be displayed</a><br /><br />The name attribute is used to create a named anchor.

If you link like this: href="http://www.w3schools.com/html", you will generate two HTTP requests to the server, because the server will add a slash to the address and create a new request like this: href="http://www.w3schools.com/html/"<br /><br />Named anchors are often used to create "table of contents" at the beginning of a large document. Each chapter within the document is given a named anchor, and links to each of these anchors are put at the top of the document.<br /><br />If a browser cannot find a named anchor that has been specified, it goes to the top of the document.

See how it is done in the first example below.</p><p style="font-weight: bold;"><br /></p><p style="font-weight: bold;"><br /></p><p><br /></p><br /><br /><br /><br /><p class="intro"><br /></p> <div style='clear: both;'></div> </div> <div class='post-footer'> <div class='post-footer-line post-footer-line-1'> <span class='post-author vcard'> Posted by <span class='fn' itemprop='author' itemscope='itemscope' itemtype='http://schema.org/Person'> <meta content='https://www.blogger.com/profile/14373191684181184640' itemprop='url'/> <a class='g-profile' href='https://www.blogger.com/profile/14373191684181184640' rel='author' title='author profile'> <span itemprop='name'>atozmusic</span> </a> </span> </span> <span class='post-timestamp'> at <meta content='http://html-new-tutorials.blogspot.com/2007/12/introduction-to-html.html' itemprop='url'/> <a class='timestamp-link' href='https://html-new-tutorials.blogspot.com/2007/12/introduction-to-html.html' rel='bookmark' title='permanent link'><abbr class='published' itemprop='datePublished' title='2007-12-18T10:54:00-08:00'>10:54&#8239;AM</abbr></a> </span> <span class='post-comment-link'> <a class='comment-link' href='https://www.blogger.com/comment/fullpage/post/7053383967919920106/6014425436580597441' onclick=''> No comments: </a> </span> <span class='post-icons'> <span class='item-control blog-admin pid-2084261205'> <a href='https://www.blogger.com/post-edit.g?blogID=7053383967919920106&postID=6014425436580597441&from=pencil' title='Edit Post'> <img alt='' class='icon-action' height='18' src='https://resources.blogblog.com/img/icon18_edit_allbkg.gif' width='18'/> </a> </span> </span> <div class='post-share-buttons goog-inline-block'> </div> </div> <div class='post-footer-line post-footer-line-2'> <span class='post-labels'> Labels: <a href='https://html-new-tutorials.blogspot.com/search/label/HTML' rel='tag'>HTML</a>, <a href='https://html-new-tutorials.blogspot.com/search/label/TUTORIALS' rel='tag'>TUTORIALS</a> </span> </div> <div class='post-footer-line post-footer-line-3'> <span class='post-location'> </span> </div> </div> </div> </div> </div></div> </div> <div class='blog-pager' id='blog-pager'> <a class='home-link' href='https://html-new-tutorials.blogspot.com/'>Home</a> </div> <div class='clear'></div> <div class='blog-feeds'> <div class='feed-links'> Subscribe to: <a class='feed-link' href='https://html-new-tutorials.blogspot.com/feeds/posts/default' target='_blank' type='application/atom+xml'>Comments (Atom)</a> </div> </div> </div></div> </div> <div id='sidebar-wrapper'> <div class='sidebar section' id='sidebar'><div class='widget BlogArchive' data-version='1' id='BlogArchive1'> <h2>Blog Archive</h2> <div class='widget-content'> <div id='ArchiveList'> <div id='BlogArchive1_ArchiveList'> <ul class='hierarchy'> <li class='archivedate expanded'> <a class='toggle' href='javascript:void(0)'> <span class='zippy toggle-open'> &#9660;&#160;
