Today I was struggling with progress bar on customer page,
the task was: creation percentage bar of people who are involved in some event, what I have got was: number of people and total number of target that company wanted to reach,
< ?php if($total == 0) $perc = 0; else $perc = $people/$total if($perc >= 1) $perc = 1; ?>
then I had to create containing div
now, I had to create second div inside containing div with $perc width of containing div
simple but it works!
