AJAX is a cross-platform technique that can be use on different operating system and web application based on JavaScript and DOM. It is a powerful approach of web application technique using client-side scripting to exchange data with the web server. This means that with AJAX, web pages increases interactivity and faster responsiveness of user interface by having an independent communication with the server. Gone are the traditional ways of web browsing whereby a new page communicates with each user's request. This creates dynamic web application user interface that renders effective usability of every desktop applications. AJAX primary purpose is to increase the web page's interactivity, speed, functionality, and usability.

Ajax, by definition, is not technology. In fact, it is an application of several technologies. Ajax incorporates several existing web application like XHTML and CSS for standard-based presentation; the Document Object Model for dynamic display and interaction; XML and XSLT for data interchange between the server and the client; the XMLHttpRequest to exchange asynchronous data with the web server; and the use of JavaScript as the core code for running AJAX application.

To understand AJAX, first we must know how the traditional web application works. The classic web interface trigger an HTTP request back to web server. The server then process and retrieve data before returning an HTML page to the users. This process as a model for hypertext medium makes technical sense. But as web application evolves this process does not make the user interface more interactive and practical.

AJAX, on the other hand, eliminates this problem. AJAX speed up the loading of any web application with the use of intermediary between the user and the server called AJAX engine. This adding of another layer application of eliminates the start-stop-start-stop nature on the web. The browser loads an AJAX engine at the start of session.

The AJAX engine allows the user interface and the application to interchange data asynchronously-independent of the communication to the server. So the interaction between the user and the web never slows down, no point of waiting for the server to do something.

AJAX is a powerful technique that grows exceedingly as web application. That is, AJAX is now part of the guiding principle as web 2.0 flourishes and become a practical reality. With the power of AJAX, many of the business and marketing web site are integrated with AJAX application server platform now. Most of the major products of Google such as Gmail, Google Maps, and Google Suggest are employing AJAX application. Other web services like the photo-sharing application Flickr, Amazon's A9.com, and the new Yahoo! maps depends on AJAX. The application of AJAX comes from simple function to the most complex program like Google Maps.

There are a number of different browsers that you must compensate for when designing your webpage's in any format (CSS, tables etc.), some of the most common browsers are : Internet Explorer 6/ 7, Firefox and Safari. The main issues that arise with CSS design is that all browsers interpret CSS differently, for example Firefox does not understand some of the CSS commands that Internet Explorer does and vice a versa.

One of the main issues I have found when designing with CSS is a problem with margins in Internet Explorer 6. I found that when using a float on a div tag that also had a margin set, the margin would actually double and then knock the whole pages layout out. After numerous late nights and an insane amount of coffee I finally found a solution to this double margin bug. By inserting a simple line of code the double margin no longer double ! That solution is as follows, by adding this line of code to your CSS div tag 'display: inline'.

Another problem I have found with CSS in Internet Explorer 6 is a problem when trying to define a div tag that has a smaller size than the base font size. This problem again can be fixed with a simple line of code this time all we need to add is the following line of code to the div tag: 'font-size:0px'. There is also another solution to this problem that should have the same effect, because the div tag auto stretches to compensate for content overflow adding 'overflow: hidden' should also resolve the problem.

Unfortunately I have been unable to cover all of the cross browser issues that you may experience when designing with CSS, but most of the problems that you may encounter can be resolved pretty easily with simple trial and error. Happy designing!

I had to run into the supermarket the other day to pick up a few items. Unfortunately for me it wasn't the store I do the normal weekly shopping at, so I was unfamiliar with where everything was. To make matters worse it was one of those massive stores where you can buy groceries and probably find a contractor to build a house for you.

Nothing bothers me more when I walk into one of those huge stores and have to spend a good hour to find a gallon of milk. Your website should not be this way either.

I have listed a few ideas that should help make your website more user friendly to your customers so they are not overwhelmed when they type in your web address, and at the same time, know they can trust you.

First and foremost you need visitors to your website. With little effort you can have about 200 to 300 unique visitors each day. That can be done just by registering your website on Google, Yahoo, Ask and the other search engines. However the goal here is to attract customers not just visitors. You will need to get those numbers up. You need to find ways to attract new customers. A good way is to advertise. If you are on a limited budget sign up for an advertising website`s free account at first, and then as sales pick up, move over to their premium account. There are a variety of advertising websites out there. Develop a plan to use them all.

Once you have visitors you need to make your website user friendly. In other words easy for someone to navigate around and find what they are looking for. Hire yourself an experienced web designer. A real good one is worth their weight in gold. They will design you a website that is not only user friendly, but also one where visitors will want to continually come back to and tell their friends about. Once that happens, the sky is the limit.

Build trust and confidence with your customers. Your customers want to know that you are not some fly by night web company. They want to know if they order from you, you will deliver and if something goes wrong, they can get a hold of you. Put on your website a contact page. Let your visitors see how they can get a hold of you via email, phone, physical address and so on. Do not forget to respond promptly to your customers when they do contact you. In today`s world of "I need it yesterday", people will move on to your competitors if they don`t hear back from you within the same day, sometimes faster.

To go along with the above tip and to add on to the trust factor, provide detailed information about your company. Post your company history, your mission statement, and what means the most to you about being in business as it relates to your customers.

So there you have it a few tips to help your website out. Implement them to build a better online presence.
