The transition from HTML to XHTML will come with a fair number of bumps. While later chapters introduce tools to help you get past those bumps – and figure out where they come from – this chapter examines what’s going to change and demonstrates a few strategies for handling those changes. Along the way, we visit the ghosts of browsers past and explore problems that exist in current browsers. In turn, you discover how prepared and unprepared various tools are for XHTML.

Even dreamed of Hacking a website? Ever wonder how to get into ones website and deface it?
Well dream it.. there’s no harm in doing that; but don’t practice it (Are you confident enough about hiding your traces behind?).
Words be, lemme tell you a few live hacks done through SQL injections. You can try right now as it works (by the time this post is written) but CONSIDER doing it at your OWN RISK. What i’m telling here is more of a Ethical Hacking; that means, know that it can be done the way I’m explaining here, and find out how to protect from being a victim yourself.
It’s simple. Most people think Hacking is for the master coders only, which rather is wrong. Of course some knowledge are required and depending on the level of security, one can break through any system. HACKING into a system can be minimize but you CAN’T guarantee a 100% secure system.. as there is always a way!!
So now, here are some sites which lack some serious security measures:

(To login, goto login on the top right, go to college login, and then choose VC)
What the web developer of these sites have done is, they forgot, or don’t know how to use a escape string function (in PHP language). I won’t go into details just for the sake of the laymen. They don’t know or haven’t implemented certain measure to exclude certain characters from being input by the user. When a site asked for a username & password, what happens is that, the code checks the username to the username existing in the database and compare with the password in the same row with the user input password. If both the conditions returns TRUE, then the user is shown the next password protected page.
Look at this: “1′ or ‘1′ = ‘1″. Put the above in the username as well as the password field (without the double quotes). Here we formed an always TRUE condition as 1 always equals to 1. Or you can change it ‘2′ = ‘2′ or anything else. Now press enter and voila, you are at the backend of those sites. You can change anything from the backend.
Most people, or rather web developers must have found out the limitations to the existing structure of the CSS”. Separating content from the looks”, that was the major aim of the existence of the CSS. However, the Cascading Style Sheet, has its own limitations.
Due to the various technologies and the front-end display structure of the various browsers, that some browsers supports some CSS functions while others doesn’t; or just interprets some functions differently.
As such, look at the screenshots carefully. The displayed page is the same webpage viewed with
different browsers, ie. Internet Explorer 7, Firefox and Google Chrome. The page is a simple static page generated with plain HTML using tables and cells, Javascript a
nd CSS. The page looks extremely perfect in Internet Explorer while in Firefox and Chrome, the alignment is different and as you can see, the cell-padding and cell-spacing seems weird. The image on the page seems to float above the navigation menu on the right.
This is the main reason why we need CSS hacks. With the use of well streamed CSS functions, you can let your page displayed in different manner according to the type of browser the user is browsing with. Changing a few things on the linked Style Sheet saves you from the repeated
work of changing every file manually.. which can quite be a mess for a large website. There will be more posts following on CSS and how to hack it, making it a more powerful design tool for a webmaster. Keep checking back.
