hi niten
There are two ways to do that.
a)
edit style.css in your theme, and add this line
b)
edit pical_coming_schedule.html in your custom template like this
<{if $block.num_rows == 0}>
<{$block.lang_PICAL_MB_NOEVENT}>
<{/if}>
<{foreach item=event from=$block.events}>
<dl style='margin:0px;'>
<dt>
<{if $event.distance == 0}>
hi dreamgear.
Thank you for your suggestion.
I agree with you.
I should set "class" into piCal's HTML.
I know its HTML is not so good.
I'm sorry I don't have time for rebuilding piCal's HTML or CSS ...
if you didn't see it already, I made a hack to remove the empty whitespace and group events that occur at the same time.
