Cool rollover effects, but no documentation

has anybody used these before?

my client wants me to use one of these effects for some buttons on our site…

but I can’t find any documentation (or ‘download’ links) here; where is code for each effect…

let’s say if I want to apply second example down the page (blue background…) I just can’t find where the code is for it (don’t even know if it’s Javascript or CSS…)

would appreciate some help if anyone is familiar with this one…

thank you…

If you “view source” you can see the html and the links to the style sheet which you can post onto the end of the URL

I actually figured it out… thank you very much…

however: main headaches I get now due to responsive/fluid design… :frowning:

how do you center elements without giving them a width???

how do I center the button here?

(obviously margin:0 auto; doesn’t work here because in order for this transition to work the button has to be position:absolute… YIKES…

thank you…

One option:

#wrapper {
    text-align: center;
}
