This lightBox has the following features. You can test it by modifying the code ^-^:
The screen can be completely masked by clicking any position on the page (at this time, it is impossible to directly control any elements including the scroll bar ), the select element can be masked without hiding in IE6 (iframe masking: After masking, if you drag the scroll bar, select will still be moved to the top layer ).
LightBox highly adapts its content and presents a perfect center state.
When the content is a single row, it is displayed in the center; when the content is multiple rows, it is displayed in the left; The content height makes the scroll bar appear when the lightBox exceeds the screen, and displays it in the top, so that readers can fully read it.
If you are interested, you can refer to the following tips for creating this lightBox:

1. Full Screen masking:

A. Hide the html/body scroll bar.
B. Use a p as the mask and a p as the page with a scroll bar.

2. single-row center, multi-row center-left method (see the demo and the presentation capability is limited ):

   
  
  
  Center a single row, left multiple rows    
 
When the content is small
 
 
 
 
Content is always time, time, and time from time to time from time to time from time to time, from time to time, from time to time
 
 
  

3. Use inline-block to implement vertical center of unknown heights (see the figure and demo, with limited presentation capabilities ):

Figure:

Code Demonstration:

   
  
  
  Method for vertical center of unknown height    
 




 
 
  

There are two details:
You can see that font-size: 0 is not displayed in the complete demo, but in the vertical center method.
Because font-size: 0 in the complete demo will make firefox3.5 readers complete reading the lightBox mouse wheel failure, the reason is unknown, you can deal with this situation.
MaxHeight can only be placed behind lightBoxContent, because bug and issue may occur in opera9.6.
