Solve the Problem of Flash blocking layer on Web pages

Solve the Problem of Flash blocking layer on Web pages
During the test paper system today, we found that flash blocks the floating layer and is displayed at the top of the screen in any case, so it cannot coexist with the layer.
Then the search will eventually solve the problem:
Make Flash not sticky the key parameter of floating object or layer: wmode = opaque
Method:
For IE, add the parameter <Param name = "wmode" value = "Opaque"/> to <Object> </Object>
Add the wmode = "Opaque" parameter to FF <embed/>"
