The design area where jQuery plays the biggest role in the Pressible experience is in the sub-header. The sub-header deafults to displaying 3 topics each showing one post.
When a user's mouse enters each Topic area the post list expands to reveal 4 more additional posts.
The entire function is less than 50 lines of jQuery and CSS, and makes use of simple jQuery functions like slideDown()
jQuery also gives us the flexibility to quickly add features using jQuery plugins. On the Pressible root site you can scroll over the text Why? in the signup box and reveal a floating block of text. This is accomplished using a jQuery plugin called Simpletip
. A great solution for a feature we wanted that we did not want to spend much time custom coding.
