**OS Compatibility - Client Side Browsing**

Client side renderings are not relevant as they are not dictated by operating system but rather the client browser.

**Client Side Browser Compatibility**

Configured Commerce is built using the CSS Framework, Foundation version 5.4.6. This means any browser requirements are dictated primarily by Zurbs Foundation CSS. Functionality implemented using AJAX or JavaScript also aligns with the browser compatibility requirements of Foundation 5.4.6.

The following information is from Zurb:

Consider this: most of today's popular browsers automatically upgrade > themselves including Chrome, Firefox and Explorer (starting with 9). > IE 8 is the last IE supported on Windows XP, which [Microsoft has > officially stopped > supporting](🔗) > a couple years ago.

Besides that, since Foundation 4, our framework is built mobile-first, > meaning it relies on media queries to layer in more complex layouts > and components. Browsers or devices that don't support media queries > will be restricted to a simple, single-column layout. In some ways, > Foundation 4 better supports IE6-7 in so much as it provides a mobile > but not entirely broken experience

People have been able to get IE8 to play nice with Foundation. Here > are some links to help you if need it:
