Hello,
1. The left/right for modules have a 12px margin on both sides so when next to each other there is some spacing. You can either remove site wide by editing here:
.module_round_box_outer, #s5_component_wrap, #s5_center_area .moduletable, .module_round_box_outer-none {
margin-left: 12px;
margin-right: 12px;
}
template.css file line 1037
Or just add the following below the above code so only modules in the center area will have the margins removed (your search box):
#s5_component_wrap .module_round_box_outer {
margin-left:0px;
margin-right:0px;
}
2. We only placed margins for modules in the left/right columns and this code is located here:
#s5_right_column_wrap .module_round_box_outer, #s5_left_column_wrap .module_round_box_outer {
padding-bottom: 50px;
}
template.css line 882
You can change so its site wide by changing:
#s5_right_column_wrap .module_round_box_outer, #s5_left_column_wrap .module_round_box_outer
to:
.module_round_box_outer
Or just add CSS to this above specific to where you need it so for example (your search box):
#s5_right_column_wrap .module_round_box_outer, #s5_left_column_wrap .module_round_box_outer, #s5_component_wrap .module_round_box_outer
