I was recently working on a small photo gallery for one of my sites. Having images with various dimensions I quickly ran into trouble aligning the photos nicely with CSS alone. What I wanted was for the photos to align like they do in Pinterest; flowing smoothly next to each other despite being of various size. So I seeked out a solution that did just that.
I needed an easy way to do validation for a custom HTML form. Since the website was in Drupal which uses jQuery it was natural to look for solutions that take advantage of that library. I ended up using the jQuery Validation plugin which is simple to implement on any form.
