When your website is looking static and needs a little oomph, we look to jQuery. Known for its powerful selector engine (with the unfortunate name "Sizzle"), jQuery makes it easy to manipulate the DOM, handle events, power animations, and enable AJAX.
jQuery is the ideal choice for building animated website features, like buttons that pop when you hover, or tabs that slide down when you click them. jQuery is Lintel's preferred library for those type of features on the majority of the websites we help clients build, for all browsers, including mobile devices. (For heavy lifting, we'll pass on jQuery and use something like AngularJS.)
