Whats the process for customizing php?

[ausdigitalmedia]

Ok so I am trying to get my head around the process for customizing a wordpress php site.

 

I've been doing this for a while and generally just use firebug on Mozilla to find the css code a tweak it.

 

But now I need to go to the next step.

 

Lets take this page as an example.

I want to change the css code for the text boxes from this

input, textarea { padding: 5px; border-color: #CCCCCC #EFEFEF #EFEFEF #CCCCCC; border-width:1px; border-style:solid; -moz-border-radius: 3px; -webkit-border-radius: 3px; border-radius:3px; color: #777;background:url("/inputbg.jpg") ; font: 300 0.9em/0.9em 'Cardo',arial,sans-serif; }

to this

.input, textarea2 { padding: 5px; border-color: #CCCCCC #EFEFEF #EFEFEF #CCCCCC; border-width:1px; border-style:solid; -moz-border-radius: 3px; -webkit-border-radius: 3px; border-radius:3px; color: #777;background-color: #DDDDDD; font: 300 1em/1em 'Cardo',arial,sans-serif;}

But I only want to do it for this page and not the rest of the site.

So what is the process that I should use for finding the code and then changing the style?

 

Thank you.

Have you looked into creating a separate page template?
