Question

#! /usr/bin/perl 
use strict;
use warnings; #Always use these!
my @no = (1 .. 100); 
foreach(@no) { 
print   "\#world" . $_ . " \{
        background: url(/images/1.png) 0 0 no-repeat;
        float: left;
        width: 1%;
        height: 2%;
        position: absolute;
        top: " . $_ . "\%;
        left: " . $_ . "\%;
        z-index: -1;
        margin-top: -10px;
        margin-left: -10px;
    \}

    \#world" . $_ . ":hover \{
        background-position: 0 -20px;
        cursor: pointer;
    \}"; 
}

currently this perl script outputs #world1, top: 1%; left: 1%; where the percentages are the same. How can i modify the script to output world(1 through to 100) top: 1%; left: (1% through to 100%)%; world(101 through to 201) top: 2%; left: (1% through to 100%)%; up to world(19001 through to 20000) top: 100%; left: (1% through to 100%)%;

Answer 1

This will add a unique number for $world for every top/left value pair.

my $world = 1;
for my $top (1 .. 100) {
    for my $left (1 .. 100) {
         # print here... world$world top = $top, left = $left...
         $world++;
    }
}
