Yea, I am on a roll today doing two posts.
I have spent some time lately looking at various libs to use on a site I want to design, and by design I mean make it a true little piece of genius (and maybe learn something new while we are at it). I am not looking for a prototype replacement, I am looking more for a way to NOT use script.acuo.us, Dojo or the other libs that I thing are interesting, but they just seem to rub me wrong. I checked out the Adobe SPRY lib, decided it was too much other stuff, and eventually I kept finding myself coming back around to YUI which is pretty swanking and basically handles everything that I would have needed five others to bring together all the things I need. It is also split up in the various parts so you only bring in what you need as you need it 
see some code samples that I found and love, yay
Anyway, the yui grids css is nice for doing grid-based layouts and there are some really nice bookmarklets about that you can use to do your layouts. Just drag these to your firefox quickbar
Translucent Grid overlay
);void(myBody=document.getElementsByTagName('body')%5B0%5D);if(myDiv!=null){void(myBody.removeChild(myDiv));}else{void(myDiv=document.createElement%20('div'));void(myDiv.id='_grid_div_mrb');void(myDiv.style.background='url(http://trippledoubleyou.subtlegradient.com/tools/layoutgrid_translucent.png)');void(myDiv.style.backgroundPosition='top%20left');void(myDiv.style.position='absolute');void(myDiv.style.width=myBody.offsetWidth+%20'px');void(myDiv.style.height=myBody.offsetHeight+'px');void(myDiv.style.top='0');void(myDiv.style.left='0');void(myBody.appendChild(myDiv));}){kind=link}
);void(myBody=document.getElementsByTagName('body')%5B0%5D);void(myDiv.style.background='url(http://www.andybudd.com/images/layoutgrid.png)');void(myDiv.style.position='fixed');void(myDiv.style.width='100%');void(myDiv.style.height='100%');void(myDiv.style.top='0');void(myDiv.style.left='0');void(myBody.appendChild(myDiv));){kind=link}
And speaking of design (something I generally avoid if possible) check out this.
From here.
