Updated to cover Internet Explorer 7, Microsoft's vastly improved browser, this new edition includes content on positioning, lists and generated content, table layout, user interface, paged media, and more.Simply put, Cascading Style Sheets (CSS) is a way to separate a document's structure from its presentation. The benefits of this can be quite profound: CSS allows a much richer document appearance than HTML and also saves time -- you can create or change the appearance of an entire document in just one place; and its compact file size makes web pages load quickly.CSS: The Definitive Guide, 3rd Edition, provides you with a comprehensive guide to CSS implementation, along with a thorough review of all aspects of CSS 2.1. Updated to cover Internet Explorer 7, Microsoft's vastly improved browser, this new edition includes content on positioning, lists and generated content, table layout, user interface, paged media, and more. Author Eric Meyer tackles the subject with passion, exploring in detail each individual CSS property and how it interacts with other properties. You'll not only learn how to avoid common mistakes in interpretation, you also will benefit from the depth and breadth of his experience and his clear and honest style. This is the complete sourcebook on CSS.The 3rd edition contains:Updates to reflect changes in the latest draft version of CSS 2.1Browser notes updated to reflect changes between IE6 and IE7Advanced selectors supported in IE7 and other major browsers includedA new round of technical edits by a fresh set of editorsClarifications and corrected errata, including updated URLs ofreferenced online resources

    Leading networking authority Douglas Comer presents a wide-ranging, self-contained tour of the concepts, principles, and technologies that enable today's Internet to support applications ranging from web browsing to telephony and multimedia. This Fifth Edition has been thoroughly reorganized, revised, and updated: it includes extensive new coverage of topics ranging from wireless protocols to network performance, while reducing or eliminating coverage of older protocols and technologies. Comer begins by illuminating the applications and facilities offered by today's Internet. Next, he systematically introduces the underlying network technologies and protocols that make them possible: low-level data communications; packet switching, LAN, and WAN technologies; and Internet protocols such as TCP, IP, UDP, and IPv6. With these concepts and technologies established, he introduces several of the most important contemporary issues faced by network implementers and managers, including quality of service, Internet telephony, multimedia, network security, and network management. Comer has carefully designed this book to support both top-down and bottom-up teaching approaches. Students need no background in operating systems, and no sophisticated math: Comer relies throughout on figures, drawings, examples, and analogies, "not" mathematical proofs.

Sondhi:N.K. Sondhi’s first book was 'Management of Banking', which draws upon his experiences as a manager in the Punjab National Bank. He then turned to fiction writing, bringing forth the seen and unseen aftermaths of the partition of India in 1947 in his novel 'Cart full of Husk'. He followed it up with a short non-fiction, 'Forgotten City of Delhi (How Delhi became Delhi)'. He wrote his next book, 'A Match Made in Heaven: A 2000-year-old love story', based on the life of an Indian princess, who became first queen of Korea in 48 AD.Working with young people as he pursued social activities after his retirement, he sensed the restlessness among youngsters, who are facing a large number of problems due to stiff neck to neck competition in every field of life. Growing use of advanced technology has further alienated them from the main stream of the society. This has led him to initiate this book 'Know Your Worth' with the young and enterprising writer Ms. Vibha Malhotra.-------------------------------------------------Vibha Malhotra:Vibha Malhotra is the founder of 'Literature Studio' and editor-in-chief of the literary e-journal 'Literature Studio Review'.

Stay SuccessfulINVEST IN YOURSELF Now that you know that you have superpowers that are there within you and can be harvested whenever you need them, it is important to take time to really explore all your strengths and weaknesses. Only then can you be fully prepared to achieve your goals. But we are mostly clueless that understanding ourselves doesn’t have to be a slow, tedious process, it can always be sped up.All of us are born with inherent likes and dislikes. Even a fetus in the womb has its own taste preferences, resulting in the seemingly irrational food cravings that expecting mothers experience. These preferences, likes, and dislikes are clues to the things you will be good at. If a child enjoys painting more than singing, chances are that the child will be better at painting than he/she is at singing. You can think of these as clues that nature chose to expose to us so that we can carve a satisfying path for ourselves.Most of us, even as adults, have whims, and mostly we choose to ignore them. Even as children, we are rarely able to indulge in every whim. There are always limitations – in terms of time, finances, facilities etc. – to keep us from fully exploring what we are capable of. But these are not the only factors that stop us. The biggest factor, in fact, is our own inhibitions, especially once we are grown-ups. We are afraid of new experiences, afraid of disappointment, afraid of failure, afraid of making fools of ourselves. And this fear keeps us from taking advantage of opportunities to gather new experiences. Let us try to understand this with the example of a young girl called Shikha. Shikha and the Ideation CompetitionShikha was an editor at a publishing house. She was very good at her job and apart from being an excellent editor, she also often proposed new book ideas to the publishing house.The publishing house announced a competition in which teams would work together and come up with new book ideas that they would then present to a jury comprising of senior publishers from all over the world. The selected idea would then be converted into a book that would be sold all over the world.Shikha had never ever participated in a competition, let alone won it. She wasn’t at all confident of her abilities to work in a team. And the fact that the competition was about new book ideas was making her restless. By proposing new book ideas in the past, she had earned a reputation in that area. Her colleagues and even her boss thought of her as a creative thinker. Shikha was worried that if she participated in this competition and lost it, her reputation as a creative thinker would be tarnished too. Can you guess why she was so full of doubts? It was because she had always attributed her past achievements to good luck, and had never given herself any credit for the book ideas she had come up with. Thus, she was afraid of being exposed as someone who really did not possess any great talent.She was still in this state of dilemma when she discovered that her manager had already nominated Shikha’s name for the competition. Now she had no choice, so she decided to go with the flow. With each passing day, her desperation to win the contest increased, and by the time the date of the competition arrived, she found herself unable to sleep. She knew that she would do anything to win this competition. For the first time in her life she was this passionate about something. She wanted to give it her all.On the day of the competition, she was put in a team and the team started with discussing the various ideas that all members had. Shikha had a great idea, but when she saw more merit in the idea proposed by another team member, she voted for it to be taken up for further preparation and the final presentation. She was almost feverish with excitement. And when her team members were of the opinion that they should give their best and not really care if they win or lose, Shikha was single-minded about her goal of winning the competition. Her focus proved to be contagious and soon all her team-members too were bubbling with enthusiasm. Guided by their single goal, the group of strangers really became a team and the initial idea evolved to become something they all believed in. Though the team leader was someone else, everyone could see that Shikha was the driving force for the team. When it was time to present their idea, the team leader proposed that Shikha should do it. And the presentation left the judges mesmerized. When their team emerged the winner, no one was surprised. Their idea and their presentation of it were deemed to be the best.Once she was out of the competition frenzy, Shikha herself was surprised. She couldn’t understand what had come over her during the competition. But she was glad to discover this other Shikha. She had gone into the competition based on her creative thinking, but her team had emerged a winner because of her team spirit and leadership skills. Shikha was surprised to discover these two new skills in herself. She had never thought herself capable of what she had achieved. Most of us are like Shikha – capable, but afraid of failure and public ridicule. And this is why we do not take chances in life. We like to play safe. But one can never really truly understand oneself by remaining in a shell. Unless you experience new things, you can never experience a new you. Unless you take risks, you can never transcend your normal, day-to-day existence.But, what gives us the capacity to take risks? Our confidence on our strengths and abilities. And from where do we get this confidence? Unfortunately, it isn’t a commodity and you cannot buy it from a shop. Money can’t buy you confidence. You need to work hard to develop it. You need to test yourself, which is again done by putting yourself in situations that you feel are beyond your reach. So, this is once again a chicken-and-egg situation. But after you have been through some such cycles and are confident of the situations you can handle, you are in a better position to fix your goals.However, it is easier said than done. Unfortunately, life is not a fairy tale and this means that we will not succeed every time we take up a challenge. There will also be times when we fail. This is inevitable. We will invariably have to face problems, and this may shake our confidence. Dealing with failures is not easy. It is like a double-edged sword. If you take failures too seriously, they may end up crushing you. On the other hand, if you take them too lightly, you will not learn any lessons from them, which means that the risk that you took would go to waste. So, you need to recognize failures for what they are – failures. Nothing more, nothing less. If you fail in a challenge, it does not mean that you yourself are a failure. This is the most common mistake we commit. Failing a challenge means that you failed that challenge. You need to analyze the situation, see what you could have done better, and move on to the next challenge where you can test your learnings.This act of never giving up, will give you confidence and this confidence helps us realize our capabilities. And this, in turn, shows in our personality. We hold our head high. We walk with determination. We talk with conviction, and we are normally in a good mood. Confidence also gives us perseverance – the ability to keep going after a failure. If you haven’t invested in yourself, you are more likely to give up after a failure or two.Confidence helps us stay on our path and not go astray. Many hurdles and problems may block our way and discourage us, but if we have confidence, we will not let these hurdles stop us. Instead we will search for an alternate path to our goal. The Little Bird and the BranchOnce a little bird landed on a branch high up a tall tree. The jungle below was full of dangerous predators but at this height, they posed no danger to the little bird. Feeling safe and protected, the little bird rested, enjoying the beautiful view around, and feeling completely at peace. Just as the bird became used to the branch, a strong wind started blowing, shaking the entire tree. The tree swayed with such intensity that it appeared the branch would break and fall down.To other animals, this could be a matter of great worry, but the little bird was not worried. Do you know why? Because the little bird knew its own powers and strengths. Even if the branch was to fall down, the bird knew that it had wings and the ability to fly. And the bird was also aware that if this branch was to fall, there are many other branches that could be used instead. Therefore, the bird, though tiny in size, sat on the branch, braving the high wind. The animals below, all of them much stronger than the bird, were filled with much admiration for this courageous little creature who was braving difficult circumstances. The story of this small bird tells us a lot about our own self-confidence and courage. If one road is blocked there are others we can follow. And if there are no new roads, there’s always the earth on which we can make a new road.
