Having coded in many languages, and recently when using MooTools instead of jQuery, i’ve come to realise that most actual programming is pretty language agnostic. What I mean is that most languages do the same thing, just very differently, but it is how you contruct your code that makes you a good programmer
Chances are, if you are good at jQuery you will be pretty good at MooTools (after learning the new declarations etc). The same goes for in a larger extent SQL/MySQL/Oracle or ASP/PHP/Ruby etc.
This post has come from a quick bit of experimentation, trying to centre align list items.
The design called for centerally aligned list item links, and there could be 3, 4, 5 or more links. Initially I was stumped as to how to create this effect. I had considered a left margin to create the illusion of centre aligning for each possible number, but I knew there was a better way. I’m always aiming for a solution that works in the older browsers too, and this includes IE6. I don’t know why I do it to myself, especially as it apparently only has less than a 5% market share nowadays.
