I want to remove space from places shown in the picture.
What do you mean? Do you still want a border to separate the text items so removing the spaces will leave a thick border or do you want the whole lot wrapped with a single border?
For the first option you will have in your template the line
<table class="maintable" cellspacing="1" cellpadding="0" align="center" width="100%">
change to
<table class="maintable" cellspacing="0" cellpadding="0" align="center" width="100%">
A great tool for working out things like this if your are using firefox is to install the firebug plugin.
Well the thing I want is to remove that white space and just have normal 1px border
Then do as Phil suggested.
Well then I have 2px line, not 1
In that case you will need to use a little css.
Google "collapsing borders model" and it should give you all the info you need.
