окантовка(предлагаю именно такой перевод для термина "chrome" в значении "оболочка пользовательского интерфейса", так как обнаружил в книге Нильсена (Jakob Nielsen, Raluca Budiu "Mobile Usability") следующее объяснение: "We don't know who came up with the term chrome, but it was likely a visual analogy with the use of metal chrome on big American cars during the 1950s: The car body (where you sit) was surrounded by shiny chrome on the bumpers, tail fins, and the like" owant)
хром(The common user interface elements rendered around each Web Parts part control within a given zone. The chrome for a part control includes a border, a title bar, and the icons, title text, and verbs menu that appear within the title bar. The appearance of the chrome is set at the zone level and applies to all part controls in a zone. The rendering of chrome and of individual System.Web.UI.WebControls.WebParts.WebPart controls is handled by the System.Web.UI.WebControls.WebParts.WebPartChrome class)
