I want to nest the max() and min() functions as follows. $variable5 = min(max(($variable1 - $variable0), 0), $variable3); The PHP manual says/suggests that this type of nesting is possible. However, the code doesn't run …

Is using -100px or minus however many pixels considered as bad coding practise, should it be avoided? Do employers look down upon this? Example Use: [CODE] <div style="margin-left:500px; margin-top:-85px;"> <p>Home | About | Contact</p> </div> [/CODE]
