HTML

IBM introduced GML (general mark-up language) 1980's . it was a language that aimed to create web page by using headings ,text etc .After that  in 1986 , this language reintroduced by ISO(International Organization for Standardization) as SGML (Standard Generalized mark-up language) . and finally in1989 HTML(Hyper Text Mark -up Language) redesigned by Mr. Tim Berners Lee and his team.


As we know that every language has some syntax and rules that’s why HTML language has some syntax and tags.HTML uses tags to create web pages these tags are enclosed in angular brackets  < > . For ex: <any tag > .

There are two types of tags

1. Non- empty tags  (container tag)- These  type of tags include ON tag <> & OFF tag</>. ON tag is used to open any tag and OFF tag is used to close any tag.For ex:  

  •  <marquee> you are welcome in the HTML world </marquee>
  •  <font color=yellow size=9> Believe in your self</font>
Every non empty tag has some characteristics ,properties or attributes that define that tag.In above example font is a tag and color for setting the colors and size attributes is used to font size of the text.

2. Empty Tag -These type of tags don’t have OFF tag like <hr> ,<br>.

HTML Rules:
1.       Tags are enclosed in angular brackets like <html>.
2.    <Br> empty tag  doesn't have off tag </>
3.    <B> bold the text it is a  non empty tag </B>(having off tag</>)
4.    Every non empty  tag  for ex. <font> having some properties color ,size etc
5.    Order for witting html pages
   <html>
  <head>
  <title>…..</title>
  </head>

How can we apply comment inside html pages ?


If you want to write some text for learning html but  you don't want to show that text on page  then you can use    

<!— B tag is used to bold the text -->

for example

<HTML>    
<HEAD>
<TITLE> First Page </TITLE>
</HEAD>
<BODY bgcolor=#003300>
<font color= red size=12>
<center>
<b><h1> Internet</h1></b> <!— B tag is used to bold the text -->
</center>
</font>
<font size=10 color=#fff>
<P Align=”justify”>internet is a network of networks .it is a biggest    
 network in the world
</p>
</font>
</body>
</html>
