The essence of Gita is summarized below:

1. Why do you worry? Who are you afraid of? Whatever has happened has happened for the good. What is happening is also happening for the good. Whatever will happen, will be for good also. Do not repent over the past, or worry for the future. Do your duty selflessly—and to the best of your abilities—in the present only.

2. What have you lost for which you cry? You did not bring anything to this world when you were born. You are unnecessarily attached to your possessions. This attachment is the root cause of all your sufferings. Treat all your possessions as a trust property given to you by the God. Let the thoughts of ‘I’ and ‘my’ be completely wiped of your mind. Practice detached attachment. Always remember the creator, and surrender to the will of the Lord.

3. Why worry about the unavoidable death? Change is the law of nature. Atmaa (Spirit) is the abode of body, and the body is an abode for the individual soul (Jeev). This physical body was not here in the past, nor will it remain here for ever. But, the Atmaa is immortal. It neither takes birth nor dies. Atmaa only changes its bodies as you change your garments.

Semantic Markups

Good HTML structure is based on logic, order, and using semantically correct markup. Semantics is the study of language meaning. For language this is the words we use to communicate. For HTML it is the tags we use to mark a document up. An example is the p tag for paragraphs which tells the browser that the text within a p tag is a paragraph. Semantics simply means trying to make sure, the documents mean something.

If a user can see the web page as you intended it in a browser why does it matter if the document isn’t semantic? Well it matters quite a lot. Firstly Google and other search engines see the page without styles. The only way for search robots to understand which elements on the page are more important than others is through the markup. If the business name is within a Paragraph tag it is likely to get lost in other content and not be returned in search engine results. But if you put it within a Heading 1 tag the search robots know to give it more importance. So search engine optimisation is one very good reason to use semantic markup.

Secondly a document is easier to style if it is marked up correctly. If all your section headings are Heading 2 tags you only need to specify one CSS class and all section headings are styled. If in the future you want to change your design entirely a well marked up document will make the exercise simple

Thirdly many other user agents won’t understand your stylesheet, whether it be a mobile device or the next big thing on the internet. By writing semantic markup you are future proofing your documents. HTML is like a common language – if you take the time to understand it and write documents semantically your code will stand the test of time. If you choose to write poorly formed HTML it is like a dialect – some will understand you very well but others won’t understand you at all, and it is likely you will need to translate it in the future.

Examples:
Simillar tags such as <i> itallics and <em> may appear same but they need to be used in a correct contact.
simillarly heading tags and the bold, strong and font tags , though they appear same the need to be used in the correct context.

Using semantic markup you will give the following benefits

• Better search engine optimisation
• More maintainable code
• Easier code to style with CSS
• More accessible code for blind and partially sighted users
• You are future proofing your code
• You are using the right tools for the job

You can choose to ignore semantic markup if you want but you will make your job a lot harder!

Difference between Class and id in CSS:

• Id is used for referring single element in a page,
  Class can be used to refer more than one element in a page.
• Id is unique,
  Class is not unique.
• Id is used for styling one single element,
  Class is used for styling many elements in the same manner.

MooTools

Mootools are nothing but compact,modular object oriented javascript framework,intended to make the process of writing extensible and cross Browser compatible.These codes are more efficient.The are lightweight and powerful tools to handle with.The codes are designed in such a way that they never throw any exceptions.

If you want any high level scripting to be done for your web page then download the corresponding code frommootools.net and add them within the scripts of your design and use them.

Text Based Browsers

Text Based Browsers are the browsers which contains formatted HTML.
All the objects in HTML are represented only via Text format. Text Based browsers does not support any images or visual media files.

Text Based browsers are accessed only using arrow keys,they don’t use the mouse for user interaction. It consists of numbered links to navigate to other pages in web. By following which arrow mark to be pressed or which number key to be pressed these browsers can be accessed easily.

Since they don’t have any heavy content they are rendered very fast than other visual browsers. They are one among the smallest browser as well.
These Text Based browsers are mainly used for visually challenged people.

Examples of Text Based Browsers:

• Lynx
• Links
• Elinks
• DosLynx
• Retawq
• W3m….
