Not all libraries are defined in a way that is compatible with AMD and RequireJS's define() function. The author's have addressed this by including a shim directive for configuring those dependencies. One example is using the jQuery UI Layout Plugin. That plugin depends on jQuery. You can configu...

RTL (Right-to-left) support is an essential part in planning for i18n and L10n. Unlike English language which is written from left to right, many languages like Arabic, Japanese, Hebrew, etc. are written from right to left. To appeal to a more global audience, it is a good idea to plan your layouts ...
