thanks for super fast response but hmmm..
i modified the styles.php with it as follow
and edited it as this:
.hentry {border-bottom: 0px;margin:0 0 0px;overflow: hidden;}
but it still seems to take margin before the bottom copyright infos
or is there something else takin the empty space
i have these in the custom CSS box
.entry-meta, .entry-utility { display: none; visibility: hidden; }
.single-galleries .navigation { display: none; margin-top: 20px; }
