                //              Getting the style value uses the computed style for the node, so the value
                //              will be a calculated value, not just the immediate node.style value.
                //              Also when getting values, use specific style names,
                //              like "borderBottomWidth" instead of "border" since compound values like
                //              "border" are not necessarily reflected as expected.
                //              If you want to get node dimensions, use `dojo.marginBox()`,
                //              `dojo.contentBox()` or `dojo.position()`.
                // node: DOMNode|String

                // value: String?
                //              If passed, sets value on the node for style, handling
                //              cross-browser concerns.  When setting a pixel value,
                //              be sure to include "px" in the value. For instance, top: "200px".
                //              Otherwise, in some cases, some browsers will not apply the style.

                //              or return the normalized, computed value for the property when passing in a node and a style property
                // example:
                //              Passing only an ID or node returns the computed style object of

                //              Passing a node and a style property returns the current
                //              normalized, computed value for that property:
                //      |       dojo.style("thinger", "opacity"); // 1 by default

                //      |       dojo.style("thinger", {
                //      |               "opacity": 0.5,

                // example:
                //              When the CSS style property is hyphenated, the JavaScript property is camelCased.
                //              font-size becomes fontSize, and so on.
