HTML stands for HyperText Markup Language.
|
|
It is a language which allows us to write pages for the world wide web.
|
|
It is a markup language, it enables us to write webpages using code to indicate how text and data should be displayed.
|
|
In fact, html files are simple text files.
|
|
What is this markup? It is a method of organising the page's data by surrounding it with opening tags and closing tags.
|
|
This markup serves to give significance to the text that it encloses.
|
|
Like other computer languages, HTML has many versions. Here we will talk about HTML5.
|
|
|
|
**NOTE :** You can test the different tags and elements as you progress through the tutorial on a site like [codepen](http://codepen.io/pen/) in order to see their effects, understand how they work and familiarise yourself with the language.
|
|
This article is concerned principally with HTML syntax and some useful tips.

<!-- Here is an example HTML file that we are going to analyse. -->
|
|
|
|
<!doctype html>
|
|
<html>
|
|
<head>
|
|
<title>My Site</title>
|
|
</head>
|
|
<body>
|
|
<h1>Hello, world!</h1>
|
|
<a href = "http://codepen.io/anon/pen/xwjLbZ">Come look at what this shows</a>
|
|
<p>This is a paragraph.</p>
|
|
<p>This is another paragraph.</p>
|
|
<ul>
|
|
<li>This is an item in a non-enumerated list (bullet list)</li>
|
|
<li>This is another item</li>
|
|
<li>And this is the last item on the list</li>
|

|
|
|
|
<!-- An HTML file always starts by indicating to the browser that the page is HTML. -->
|
|
<!doctype html>
|
|
|
|
<!-- After this, it starts by opening an <html> tag. -->
|
|
<html>
|
|
|
|
<!-- that will be closed at the end of the file with </html>. -->
|
|
</html>
|
|
|
|
<!-- Nothing should appear after this final tag. -->
|
|
|
|
<!-- Inside (between the opening and closing tags <html></html>), we find: -->
|
|
|
|
<!-- A header defined by <head> (it must be closed with </head>). -->
|
|
<!-- The header contains some description and additional information which are not displayed; this is metadata. -->
|
|
|
|
<head>
|
|
<title>My Site</title><!-- The tag <title> indicates to the browser the title to show in browser window's title bar and tab name. -->
|
|
</head>
|
|
|
|
<!-- After the <head> section, we find the tag - <body> -->
|
|
<!-- Until this point, nothing described will show up in the browser window. -->
|
|
<!-- We must fill the body with the content to be displayed. -->
|
|
|
|
<body>
|
|
<h1>Hello, world!</h1> <!-- The h1 tag creates a title. -->
|
|
<!-- There are also subtitles to <h1> from the most important (h2) to the most precise (h6). -->
|
|
<a href = "http://codepen.io/anon/pen/xwjLbZ">Come look at what this shows</a> <!-- a hyperlink to the url given by the attribute href="" -->
|
|
<p>This is a paragraph.</p> <!-- The tag <p> lets us include text in the html page. -->
|
|
<p>This is another paragraph.</p>
|
|
<ul> <!-- The tag <ul> creates a bullet list. -->
|
|
<!-- To have a numbered list instead we would use <ol> giving 1. for the first element, 2. for the second, etc. -->
|
|
<li>This is an item in a non-enumerated list (bullet list)</li>
|
|
<li>This is another item</li>
|
|
<li>And this is the last item on the list</li>
|
|
</ul>
|
|
</body>
|
|
|
|
<!-- And that's it, creating an HTML file can be simple. -->
|
|
|
|
<!-- But it is possible to add many additional types of HTML tags. -->
|
|
|
|
<!-- To insert an image. -->
|
|
<img src="http://i.imgur.com/XWG0O.gif"/> <!-- The source of the image is indicated using the attribute src="" -->
|
|
<!-- The source can be an URL or even path to a file on your computer. -->
|
|
|
|
<!-- It is also possible to create a table. -->
|
|
|
|
<table> <!-- We open a <table> element. -->
|
|
<tr> <!-- <tr> allows us to create a row. -->
|
|
<th>First Header</th> <!-- <th> allows us to give a title to a table column. -->
|
|
<th>Second Header</th>
|
|
</tr>
|
|
<tr>
|
|
<td>first row, first column</td> <!-- <td> allows us to create a table cell. -->
|
|
<td>first row, second column</td>
|
|
</tr>
|
|
<tr>
|
|
<td>second row, first column</td>
|
|
<td>second row, second column</td>
|
|
</tr>
|
|
</table>
|
|
