Ch2. Overview:
HTML acronym for hyper text markup language. It is the most widely used language to build web pages. HTML is simply a collection of certain keywords called tags. HTML is a platform independent language i.e. It supports all operating system i.e. Linux, Windows, Mac etc.
Hyper text: The term Hyper text was coined in 1965 by Ted Nelson. It is a text which contains links to another text. Hyper text is not constrained to be linear i.e. It is written inside tags.
Markup language: is the combination of words and symbols which gives instructions on how a document should appear e.g. We use tags for Italic and bold.
Ch3. Fundamentals of HTML
1. Creating Saving and Weaving a HTML document
- A HTML document can be created by using any of the editor such as notepad which should be saved with a ".htm" or ".html" extension.
- HTML file can be viewed on web browsers like Google Chrome, Mozilla Firefox or Internet explorer.
- For creating HTML document we use predefined HTML tags which we gonna look in details later on this HTML course.
2. Basic format/Structure of HTML tags:
This is the basic structure which is always followed in every HTML document. You just have to type it in your notepad and then save it as an extension ".htm" or ".html" and your HTML document will get created.
<HTML>
<HEAD>
<TITLE> This will be displayed as your title for your document</TITLE>
</HEAD>
<BODY>
</BODY>
</HTML>
Ch4. Tags in HTML
Tags in HTML are instructions that are embedded directly into text of documents. HTML Tags are signals to a web browser that what it should do something other than just throw the text on screen. All HTML tags begin with an open angular bracket "<" and end with closing angular bracket ">" e.g.
<tag name>
Types of HTML Tags
HTML tags are of two types:
i). Container(paired):- Tags which have both opening and closing i.e. they hold text and other HTML tags in between the tags e.g.
<b> some text in bold </b>
<i> some text in italic </i>
ii). Empty tags:- these are tags which have only opening and no endings are known as empty tags in HTML.
Body tag Attributes:-
This tag is used for defining body attributes i.e.
<body bg color="red">
<body background="image">
<body text="color name">
<body left margin="pixel">
similarly, it's
<body top margin="pixel">
<body right margin="pixel">
FORMATTING WEB PAGE:-
i). Section Heading: There are 6 section heading tags in HTML. It starts with <h1> tag and goes down to <h6>. If a content is written in <h1> tag then it is the biggest of all in size, <h2> heading tag are slightly smaller in size as compared to <h1> tag and this trend follows till <h6> and <h6> is the smallest section heading tag available in HTML.
<H1> Biggest of all</H1>
<H2> Bigger</H2>
<H3> Big</H3>
<H4> Small than h3 tag </H4>
<H5> Smaller</H5>
<H6> Smallest of all the above</H6>
ii). Paragraph Tag: this tag indicates two paragraph to get separated by a blank line.
i.e.
<p> hello this text is written inside a paragraph tag and it will get separated with a blank line</p>
Attributes of Paragraph Tag
Alignment attribute:
This align attribute is used in paragraph to arrange the paragraph
according to the ones look and feel. A paragraph could be aligned in 4
ways using align attribute. i.e.
align="right/left/center/Justify" e.g.
align="right/left/center/Justify" e.g.
| <p align="right">
----------------------------------------
--------------------------------------
---------------------------------------------
--------------------------------------------
-------------------------------------------------
-------------------------------------------------
--------------------------------------------
| <p align="left"> ------------------------------------------- ---------------------------------- ------------------------------------- -------------------------------- -------------------------- -------------------------------------------- -------------------- |
| <p align="center">
------------------------------------------
-------------------------------------
---------------------------------
---------------------------------------------
-----------------------------------
--------------------------------
----------------------------------------------
----------------------------------------
| <p align="justify">
------------------------------------------
------------------------------------------
------------------------------------------
------------------------------------------
------------------------------------------
------------------------------------------
------------------------------------------
------------------------------------------
|
We can also pass attributes like bgcolor to change the background color of the paragraph
e.g.
<p align="right" bgcolor="blue"> Your paragraph text here</p>
Here the text written inside the <p> </p> tag will get aligned right and will have blue color.
iii). Line Break Tag: this is an empty tag and is used whenever we want to start a new line.
