Systems and methods are provided for style sheet language coding that maintains a desired relationship between display elements. An authoring tool receives a desired attribute for a first display element, and the authoring tool generates style sheet language code for defining attributes of at least one other display element to maintain a predefined relationship between the display elements. Accordingly, as a developer defines (e.g., creates, modifies, etc.) attributes for one of the display elements, the authoring tool autonomously updates the style sheet language code to define the attributes of the other display elements to maintain the predefined relationship therebetween. In certain embodiments, the authoring tool provides an interface that enables a developer to directly define certain attributes of a display element, wherein the authoring tool generates style sheet language code to indirectly define the attributes in a manner that reflects the developer's direct definition thereof.
