Lecture 5 - HTML DIV Tag in Hindi

     
The <div> tag:-



This is the very important block level tag which plays a big role in grouping various other HTML tags and applying CSS on group of elements. Even now <div> tag can be used to create webpage layout where we define different parts ( Left, Right, Top etc) of the page using <div> tag. This tag does not provide any visual change on the block but this has more meaning when it is used with CSS.

Lecture 4.1 - CSS Introduction & types of CSS including ID and Class

     
Cascading Style Sheets, fondly referred to as CSS, is a simple design language intended to simplify the process of making web pages presentable.

CSS handles the look and feel part of a web page. Using CSS, you can control the color of the text, the style of fonts, the spacing between paragraphs, how columns are sized and laid out, what background images or colors are used, layout designs,variations in display for different devices and screen sizes as well as a variety of other effects.

CSS is easy to learn and understand but it provides powerful control over the presentation of an HTML document. Most commonly, CSS is combined with the markup languages HTML or XHTML.



Advantages of CSS:-
  1.     CSS saves time − You can write CSS once and then reuse same sheet in multiple HTML pages. You can define a style for each HTML element and apply it to as many Web pages as you want.
  2.  Pages load faster − If you are using CSS, you do not need to write HTML tag attributes every time. Just write one CSS rule of a tag and apply it to all the occurrences of that tag. So less code means faster download times.
  3. Easy maintenance − To make a global change, simply change the style, and all elements in all the web pages will be updated automatically.Superior styles to HTML − CSS has a much wider array of attributes than HTML, so you can give a far better look to your HTML page in comparison to HTML attributes.
  4. Multiple Device Compatibility − Style sheets allow content to be optimized for more than one type of device. By using the same HTML document, different versions of a website can be presented for handheld devices such as PDAs and cell phones or for printing.    
  5. Global web standards − Now HTML attributes are being deprecated and it is being recommended to use CSS. So its a good idea to start using CSS in all the HTML pages to make them compatible to future browsers
  6. Offline Browsing − CSS can store web applications locally with the help of an offline catche.Using of this, we can view offline websites.The cache also ensures faster loading and better overall performance of the website.
  7. Platform Independence − The Script offer consistent platform independence and can support latest browsers as well.
Who Creates and Maintains CSS?

CSS was invited by Håkon Wium Lie on October 10, 1994 and maintained through a group of people within the W3C called the CSS Working Group. The CSS Working Group creates documents called specifications. When a specification has been discussed and officially ratified by W3C members, it becomes a recommendation.

Lecture 2.2 - HTML List in Hindi

     
HTML offers web authors three ways for specifying lists of information. All lists must contain one or more list elements. Lists may contain:

<ul> - An unordered list. This will list items using plain bullets.
<ol> - An ordered list. This will use different schemes of numbers to list your items.
<dl> - A definition list. This arranges your items in the same way as they are arranged in a dictionary.

As told earlier, HTML is a markup language and makes use of various tags to format the content. These tags are enclosed within angle braces <Tag Name>. Except few tags, most of the tags have their corresponding closing tags. For example <html> has its closing tag </html> and <body> tag has its closing tag </body> tag etc.

Basic HTML Page Structure:-

We can now meet or first three HTML tags html, head and body

Note that these specify the basic anatomy of every HTML page.

<html>
      <head>
            head elements go here
      </head>

       <body>
