HTML
-----
Today i just to refresh my brain i go through the w3schools.com doctype--rules of an
language it tells the mark up langauge to browser
DTD(document type definition)
1.strict---it contains all html elements,except font and frameset
2.Transitional--it supports all html elements and attributes except frameset
3.Frameset---it supports all elements and attributes
why we saying before we starting any html language just go through any site it saying a
huge big 3 line statement containing
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01
Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd"> like this ....any website has validated by some
webstandards the rules must follow any website as per the browser understanding the
document are coming from html and browser will parse...
For validating any website just go to http://validator.w3.org/ in that validator website
you may enter url or just copy paste your own code or website html code it will validate
the errors and returned to you .. and then today i refresh the html language becuase i dont
want to forget anything.
<iframe> This tag is very useful to create an certain area in browser window we can
create an new small window in html pages we can declare the height and width
<target> using target we can fetch the element from one location to another location
Now the Latest version of Html is HTML-5 it supports the
<canvas>
<svg>
<video>
new html5 supports videos the biggest challenge is in future versions of browsers we
need not depend on flash player its an heavy weight one using canvas element in html5
supports to draw graphics and pictures in browser with the help of javascript using svg
element we can draw circles, ovals,rectangles,polygon,polyline,line etc., previously for
this we need to depend on some other plugin but now observe web becomes most user
friendly
