Set the height attribute of mainFrame to 100%

I don’t know where to set it, I click The mainFrame of the frame in the lower right corner of the DW is the middle frame, but there is no attribute for setting the height in its attribute bar. If it is set in the statement, how should it be set?

Dynamically set the height of mainFrame

I also encountered this problem. If anyone knows the solution, please give me some advice and explain it in detail, thank you

rows=" 177,*,150"
Since there is already * in the middle, it can be done automatically.
If three frames are displayed on the same page, the content cannot be fully displayed. Will there not be more frames in the future?
