U evo, ovaj alat me oborio s nogu:
http://www.getfirebug.com/
“Firebug integrates with Firefox to put a wealth of development tools at your fingertips while you browse. You can edit, debug, and monitor CSS, HTML, and JavaScript live in any web page.”
A ovo mi je omiljena funkcija:
“When your CSS boxes aren’t lining up correctly it can be difficult to understand why. Let Firebug be your eyes and it will measure and illustrate all the offsets, margins, borders, padding, and sizes for you.”
Savrseno za one koji vole da kodiraju rucno, a ima i debugger za javascript.
