In general, for the resolution of 800 * 600, the scroll bar of IE basically accounts for 28 pixels, and if the page fills filled with the user window, its width should be, 772px, and the height has been roughly calculated, it should be reduced. 170px, 600-170 = 430px
Similarly, if it is normal, if it is normal, the recommended maximum page width and page height are:
1024-28 = 996 PX
768-170 = 598 PX
In fact, you should remember 28 and 170 these two numbers, huh, huh. However, the specific browser should be made for specific browsers.
