XHTML Slicing The Key For Cross Browser Compatibility
Websites should be executed on various available browsers to check its compatibility. Browsers like Google Chrome and Mozilla Firefox are the latest versions and website should experience no problems while displaying on these browsers.

The compatibility parameter is necessary because it is annoying for a visitor if a site is downloading very slowly on the browser.
In a case if compatibility is not according to the various browsers, your visitors may leave the site and opt for other. It is harmful for any website since online business is dependent on the traffic.
If the result is not proportionate with the traffic then you should think seriously about it. The xhtml slicing is the main function of conversion. Slicing should be carried out carefully while programmer is going to convert PSD to XHTML.
Slicing means slice different part of the Psd for ease in conversion process. In general sense, it is like to cut down a big buck into small parts. This way it is easy to convert every part into identical html counterpart.
Psd file format is comprised with different layers and every layer should be dealt separately while converting. It is true that different conversion operands (software) are available but a hardcore programming by a person is necessary for the best results.
For the sake of compatibility with browsers, the XHTML slicing is the main concern. It is the first step in conversion and handled with care since it is not predictable that the particular visitor will use which particular browser.
