Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Responsive design philosophy
Foundation allows designing for multiple screen sizes simultaneously easily, meaning your content will always fit.
Pro Uses REMs instead of pixels
Foundation uses REMs instead of pixels, meaning you don't have to state an explicit height, width, padding, etc, for every device. Simply put, using REMs means you can just state font-size: 80%; and have the whole component (and its nested elements) shrink by 20%.
This is great for making your site mobile friendly. There is also a Sass function in Zurb that converts pixels to REMs so if you're used to thinking in pixels, you don't have to learn a different system.
Pro No style lock-in
Styles are purposefully undeveloped to encourage differentiation between different sites using Foundation.
Pro Block grid
Foundation has a feature called block grid. Block grid gives designers the power to divide the contents of an unordered list into a grid that is evenly spaced. Furthermore, Foundation also takes care of collapsing columns as well as removing gutters.
Pro Easy customization
Just by looking at the name, Foundation merely provides designers with a foundation of sorts on which they can build their design. It can be customized easily through SASS, a powerful CSS pre-processor or by overriding the default CSS styles.
Pro Easily extensible with a selection of add-ons
There's a variety of front-end templates, icon fonts, responsive table examples, SVG icons and stencils that help you quick-start or easily improve on your site.
Pro Support for off-canvas navigation
Foundation comes with an easy way of creating off-canvas menus.
Pro Uses Interchange to load responsive content
Foundation comes with Interchange, it makes use of media queries to load images responsively and create content that's suited to different browsers and devices.
Pro RTL support
Allows easily changing text direction.
<html class="no-js" lang="ar" dir="rtl">
Pro Built-in form validation
Foundation comes with Abide plugin, an HTML5 form validation library.
Pro Good mobile support
Foundation was one of the first frameworks to adopt a mobile-first philosophy. By focusing on mobile design first, Foundation makes designers think on what kind of content is important, relevant and interesting to the users without thinking too much on the space.

Cons
Con Can be hard for beginners to grasp
Since Foundation is built to be customizable, it's default style may not be very appealing for most. While it's true that most production-ready websites shouldn't be using the default style of a css framework (they would all end up looking the same), this is even more true for Foundation.
Con Needs more pre-built components
Example would be a scroll-spy not only for one cell, but cell to cell.
Con Not UMD pattern in core
This problem will bring attention when used with Angular, React and other JS framework. It is important to know that they create app version of this framework.
Con Documentation is a bit better than average
Documentation could be written better and clearer, with many more example than they currently have. Sometimes hard to find solutions for detailed css problems.
Con Too expensive
The icons I need are in the pay plan.
Con You will never use all icons
This means you'll have a lot of useless data (unused icons) being load into your application.
