I propose to add new value of 'glow' to the list of outline-style values. Glow is an outline where color intensity (opacity of outline-color) is a function of distance. Usually glow is made by applying Gaussian 2d filter to pixels of some image. Here is a sample of rendering elements with outline-style:glow; http://www.terrainformatica.com/w3/outline-glow-sample.png Meaning of outline-width and outline-offset when outline-style:glow : Sum of outline-width and outline-offset gives filter radii. outline-offset determines shape of the filter as presented here: http://www.terrainformatica.com/w3/outline-glow-filter.png Due to specifics of outline rendering (it is being drawn on top of siblings of the element) outline is a best place to define and render such effects. -- Andrew Fedoniouk. http://terrainformatica.com
