Cascading Style Sheets (or CSS for short) have slowly but surely become a website design standard over the past few years. It was not that many years ago that people used Frames to position their content across their web pages and Tables gradually replaced this. Many low-end website developers are still very comfortable with Tables, as it does what it says on the tin. However, more and more people are now moving over to CSS, as virtually all the layout options can be achieved using the code.

One major problem with CSS is that not all Web browsers produce the same results and it has not been helped in the past by the various browsers employing their own way of interpreting certain CSS conventions. You can think your CSS design looks OK in the current version of your preferred browser and can then be crestfallen when you view your Web pages in another version that has destroyed the formatting. Therefore, when moving over to CSS, it is important that you use the capabilities that are consistently supported across the entire range of popular browsers. It is interesting that the new version 7 of Microsoft's Internet Explorer has fixed a number of earlier anomalies, but many people are now waking up to the reality that IE7 has in fact caused problems arising from their earlier workarounds!

So why not bother with CSS, if Tables work for you? The principal advantages are as follows:

1. Web page code is generally much easier to follow;

2. The amount of code used to achieve the same result is much less. The general view is that by switching to a CSS layout, the typical page size reduction is between 50 - 60 per cent;

3. Download speeds for CSS pages are generally faster than their Table-driven counterparts. This is because browsers have to read through the table code twice before they are able to display the contents. They do this firstly to figure out the structure and then again to understand the content. It should also be recognised that a Table's contents can only be presented to the screen in one go, whereas CSS content will drop in separately, thereby giving a better user experience. It is also possible to govern the order in which specific screen elements appear, so the user is not distracted by the more bulky and slower to load image files. Furthermore, because all the code involved with CSS page layout is held in one external CSS document and is cached, it is faster than Table layouts that need to be interpreted every time a new page is displayed;

4. It is much easier to edit existing pages and to add new pages, particularly in the area of subtle formatting amendments. For example, you can change the font or colour scheme across an entire website in literally minutes;

5. CSS delivers enhanced accessibility. In recent years the number of people using web browsers on hand-held devices has risen significantly and CSS plays an important function in delivering content to PDA's etc through additional CSS documents. This just isn't possible with Table-driven layouts;

6. CSS is considered to be more Search Engine friendly because they can spider CSS pages quicker. However, it remains to be seen if this has any tangible benefits such as an improvement on the your page ranking.

On the flipside, there are a few disadvantages to CSS web page design you should consider:

1. As compared with Tables, CSS involves a much bigger learning curve;

2. Because of cross browser support issues, the time spent implementing workarounds should not be underestimated;

3. New browser versions can catch website developers napping if you are not careful. You can find that earlier workarounds have been overcome and the look of your website has changed overnight.

Ultimately, your decision on whether or not to move over to see CSS will probably depend on your level of technical capability and the time you're able to devote to understanding CSS layout alternatives.

Recovering lost data is expensive. Regardless of whether you will attempt to recovery your data yourself, or send your hard drive out for recovery, the cost is quite prohibitive. The only way to guarantee that you will never require such a service is to continually make backup copies of your files and to store them securely. Even this is not really a guarantee, but it will provide you with the security of knowing that if you computer should crash or experience major hardware failures, your data can be recreated.

Data recovery is the process where lost data is recovered from broken, damaged or inaccessible media storage or hard drives. Data recovery can also be used to explain the process of restoring lost or deleted files on a hard drive.

There are many different data recovery software packages available to consumers who prefer to attempt restore data themselves. However, in most situations when a hard drive needs to be recovered, the only option is to send it to a service provider who is skilled at data restoration.

Here are some of the applications that you might want to try if attempting recovery on your own:

1. File Recovery for Windows by Active @ Data Recovery Services
2. File Recover 6.1 for Windows by PC Tools Software
3. GetDataBack by Runtime Software
4. Recover My Files by GetData
5. R-Undelete by R-tools Technology Inc.
6. Undelete 5 by Diskeeper Corporation
7. WinUndelete by WinRecovery Software

These software packages range in price and level of effectiveness.

Here are some useful things that you should know, courtesy of http://www.800tech.com:

1) Back up As mentioned above, you should back up your data routinely. Having a back up copy of your data is one of the best defenses against lost data and the need for recovery in the first place.
2) Hard disk noise
Anytime you hear a churning or clicking noise inside of your computer it means trouble. You should seek assistance as soon as possible from an authorized repair center.
3) Do not attempt the Recovery If you face any problem of data loss, do not attempt to recover data yourself unless you are an expert. Attempting the data recovery your self from the hard disk may further complicate the problems.

If you are in need of data recovery services, you should always work with a recovery center that guarantees their process. You should never be charged for unsuccessful data recovery, and you should be permitted to see your data before you are charged for the service. You should also be given an accurate quote for the total recovery cost before work begins.

A certified quality recovery service provider like 800Tech.com can help you with the process of recovering lost or damaged data at the best price and within the shortest amount of time in the industry.

You should never pay for unsuccessful recovery efforts, and also be sure that the company with whom you work guarantees the viability of your data in a contract prior to beginning work. Access to filenames is great, but what you need is content.
