+Edit CSS Style plug-in notes
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Unlike WYSIWYG editor functionality that operates only on the selected text,
+typically by inserting new HTML elements with the specified styles.
+This plug-in operates on the HTML blocks surrounding the selected text.
+No new HTML elements are created.
+
+This plug-in only operates on the surrounding blocks and not the nearest
+parent node.  This means that if a block encapsulates a node,
+e.g <p><span>text</span></p>, then only the styles in the block are
+recognized, not those in the span.
+
+When selecting text that includes multiple blocks at the same level (peers),
+this plug-in accumulates the specified styles in all of the surrounding blocks
+and populates the dialogue checkboxes accordingly.  There is no differentiation
+between styles set in all the blocks versus styles set in some of the blocks.
+
+When the [Update] or [Apply] buttons are pressed, the styles selected in the
+checkboxes are applied to all blocks that surround the selected text.
