JQuery... honestly it's lovely and it works and it's fabulous BUT figuring it out can be a pain and a half. I did a lot of flailing in a JavaScript class the semester before last to figure it out, and a lot of the time getting your code to work can be finicky depending on what version of JQuery you use, whether you've got the right selectors, if you've made the right sacrifices to the JQuery gods..
UM YES I'm annoyingly chatty about HTML/CSS so I'm going to go add you on AIM right now. (I'm coldisthewater!) AWWW YISS except I haven't even gotten to put up my favourite yet (HBIC Pam).
