Abstract: Aspects of the present disclosure simplify identification of potential non-visibility of user interface (UI) components when a responsive web page is rendered by disparate devices. In one embodiment, a browser is instructed to display the web page in a viewport of a desired size. Upon the browser rendering the web page in the viewport, a data structure (e.g., DOM) generated by the browser is examined to determine whether each of the components of the responsive web page is visible or non-visible within the viewport, and a corresponding visibility report is generated. The steps of instructing and examining may be performed iteratively for a number of viewports of corresponding sizes. The visibility report is then generated as a two-dimensional matrix indicating whether each component (along a first dimension) is visible or non-visible when the web page is rendered in a corresponding viewport (along a second dimension).

Abstract: According to an aspect of the present disclosure, a repository of (user interface) components is maintained, with each component having an associated interface definition. A user interface containing a set of components rendered on a display unit is then provided, the set of components being contained in the repository. In response to receiving from a user, a selection of a component rendered on the display unit, the interface definition of the selected component is made available in defining a new user interface in a development system.
