It turns out that today, any developer to create a site should ensure that the site is without errors and functioned in the same way Internet Explorer 6, Internet Explorer 7, Mozilla Firefox 2, Opera 9. Checking functioning in other browsers often not required. If necessary, browse the site from mobile phones, this should be considered separately. Other technical issues raised often enough: what is Screen resolution of the user viewing the site? Using again the service LiveInternet, easy to learn that about 83% of users use a resolution of 1024×768 and 1280×1024, while the second gradually replaces the first.

In the end, it was under these licenses should optimize your site.
The web designers are often mounted high-resolution monitors, and they have no idea how many people use a resolution of 1024×768. Horizontal scroll bar at this resolution reduces the quality of the site, because it will be visible almost half of the users. Resolution of 1600×1200 or higher while using about 4% of users. Many of them do not open a browser window to full screen, so it is quite possible that when larger than the width of 1280, permits the side of a blank area.

If you optimize your site for just under a permit, most users will too large empty field.
If you use 'rubber layout' with the changes from 800 to 1280, it is very difficult to achieve high-quality appearance of the site.

Most likely, the appearance of the site on your mobile phone will not be so as an ordinary computer, as screen resolution can differ by almost an order. If no special requirements, it is best to optimize the site for authorization from 1024×768 to 1280×1024.

If the site must be accessible from mobile phones, should develop a separate solution for this.
