HTML


HTML
stands for the Hyper Text Markup Language. Web sites are created with the codes of the HTML language. HTML is extremely easy to learn, and it's completely free to code web sites with it. (You don't have to pay a license fee to use HTML.)





The basics of the HTML language are easy to learn with a few short lessons.
HTML allows web sites to bring together graphics, music, video and links. The HTML code you type can be viewed on any computer. If you type it on a Windows PC, it can be viewed on both Windows and Apple computers, and if you type it on an Apple Mac, you can view it on both Macs and PCs. It doesn't matter what computer someone uses, as long as it has Internet access.

HTML is short for HyperText Markup Language.


  • Hypertext is simply a piece of text that works as a link.
  • Markup Language is a way of writing layout information within documents.
Basically an HTML document is a plain text file that contains text and nothing else.
When a browser opens an HTML file, the browser will look for HTML codes in the text and use them to change the layout, insert images, or create links to other pages.
Since HTML documents are just text files they can be written in even the simplest text editor.
A more popular choice is to use a special HTML editor - maybe even one that puts focus on the visual result rather than the codes - a so-called WYSIWYG editor ("What You See Is What You Get").
Some of the most popular HTML editors, such as FrontPage or Dreamweaver will let you create pages more or less as you write documents in Word or whatever text editor you're using.
However, there are some very good reasons to create your own pages - or parts of them - by hand...

WHY LEARN HTML?
It is possible to create webpages without knowing anything about the HTML source behind the page.

There are excellent editors on the market that will take care of the HTML parts. All you need to do is layout the page.

However, if you want to make it above average in webdesign, it is strongly recommended that you understand these tags.

The most important benefits are:



  • You can use tags the editor does not support.
  • You can read the code of other people's pages, and "borrow" the cool effects.
  • You can do the work yourself, when the editor simply refuses to create the effects you want.
You can write your HTML by hand with almost any available text editor, including notepad that comes as a standard program with Windows.

All you need to do is type in the code, then save the document, making sure to put an .html extension or an .htm extension to the file (for instance "mypage.html").
Basically, a computer sees an "A" as simply an "A" - whether it is bold, italic, big or small.

To tell the browser that an "A" should be bold we need to put a markup in front of the A.

Such a markup is called a Tag.

All HTML tags are enclosed in < and >.

Example: a piece of text as it appears on the screen. 




This is an example of bold text.

HTML: the HTML for the above example:



This is an example of bold text.

As you can see, the start tag  indicates that whatever follows should be written in bold. The corresponding end tag  indicates that the browser should stop writing text in bold.
All normal webpages consist of a head and a body.


    Head     

     Body     
  • The head is used for text and tags that do not show directly on the page.
  • The body is used for text and tags that are shown directly on the page.
Finally, all webpages have an  tag at the beginning and the end, telling the browser where the document starts and where it stops.

The most basic code - the code you will use for any page you make, is shown below:

HEAD SECTION
The head section of the webpage includes all the stuff that does not show directly on the resulting page.

The  tags encapsulate the title of your page. The title is what shows in the top of your browser window when the page is loaded.
Right now it should say something like "Basics - Html Tutorial" on top of the window containing this text.

Another thing you will often see in the head section is metatags. Metatags are used for, among other things, to improve the rankings in search engines.

Quite often the head section contains javascript which is a programming language for more complex HTML pages.

Finally, more and more pages contain codes for cascading style sheets (CSS).
CSS is a rather new technique for optimizing the layout of major websites.

Since these aspects are way out of reach at this stage we will proceed with explaining the body section.


BODY SECTION
The body of the document contains all that can be seen when the user loads the page.

In the rest of this tutorial you can learn in detail about all the different aspects of HTML, including:



  • Text
    • Formatting
    • Resizing
    • Layout
    • Listing
  • Links
    • To local pages
    • To pages at other sites
    • To bookmarks
  • Images
    • Inserting images (GIF and jpg)
    • Adding a link to an image
  • Backgrounds
    • Colors
    • Images
    • Fixed Image
  • Tables
  • Frames
  • Forms
  • Metatags
  • Hexadecimal Colors
HOW TO LEARN MORE
This introduction presented you with the very basics of HTML.

In the rest of this tutorial you can study each of the different HTML tags in detail.

To the upper right on all pages you will find the HTML tutorial menu.

The links are arranged so you can approach this tutorial as an ongoing course.

Each link will take you to a "chapter" - 5 to 10 pages - explaining the selected topic in depth.

If you are completely new to HTML, you should start with the chapter about text and work your way through the links - ending with the chapter about hexadecimal colors.

Once you become familiar with HTML you could proceed to the javascript section, the java applet section or the Shockwave Flash section.



INTRODUCTION
To enter text on your pages - all you have to do is simply enter the text.

If you do not specify any attributes for text it will use the default size, font etc. of the visitor's browser.


Browsers can only show fonts available on the visitor's PC.

Therefore you are limited to using the fonts that are available on almost any computer.

If you need to use a fancy font, you should use your graphics program to make an image with the text. This will assure that the visitor will see it - even if he doesn't have the fancy font you're using.

Since images take up much more space than plain text, thus increasing download time, you should use this option with care.


On the following pages you will learn how to customize the font settings - both on normal text and text that works as a link.

Furthermore, you will learn to control how the text aligns on your pages.

Now click the Read More link to get started...



BASE FONT
To specify the overall font for your page add the  tag at the beginning of the  section.

Example: The page as it looks in the browser.





Hello! This is my page.
All text looks the same
since I only specified a basefont.

HTML: The code to produce the above example.



Hello! This is my page.

All text looks the same

since I only specified a basefont.

The color attribute selects the desired color for your text. The face attribute selects the desired font.

Note:
If you enter a list of fonts, like in the example, the browser will use the first font in the list available on the visitor's computer.

The size attribute specifies the desired size, between 1 (smallest) and 7 (biggest).

FONT
The  tag will change the font.

Example: How the output looks in the browser.





Hello! This is my page.

This local text looks different.

This text looks like the first line.

HTML: The code to produce the above example.



Hello! This is my page.



This local text looks different.



This text looks like the first line.

The color attribute selects the desired color for your text. The face attribute selects the desired font.

Note:
If you enter a list of fonts, like in the example, the browser will use the first font in the list available on the visitor's computer.


TEXT LINKS
The tags used to produce links are the  and .
The  tells where the link should start and the 
 indicates where the link ends.

Everything between these two will work as a link.

The target of the link is added to the  tag using
the href="http://nagawebdesigningtutorials.blogspot.com" setting.

The example below shows how to make the word here work as a link to yahoo.

You simply: 


TEXT FORMAT
These are the tags for text formats:





textwrites text as bold
textwrites text in italics
textwrites underlined text
textlowers text and makes it smaller
textlifts text and makes it smaller
textguess yourself! (Note: Netscape only.)
textstrikes a line through the text
textwrites text as on a classic typewriter




text
writes text exactly as it is, including spaces.
textusually makes text italic
textusually makes text bold

Note:
The  tag is only supported by Netscape browsers, and should be avoided.
