[Yurii Orishchuk]

Hi Spark,

Please try following JS code:

pre

.continer4 {
position: relative;
}
centerimage4 {
position: absolute;
top: 50%;
left: 50%;
margin-left: -100px !important;
margin-top: -100px !important;
}

/pre

Regards.

Yurii
I follow you code.
in the edit mode,I change the predefined screen size will be correct.
but when I use the test mode to preview app,
it will get horizon center,but not vertical center.
did I do something wrong?
