The parser does care somewhat. Depends on the browser In my research I have found that they load aspects before dynamics.
Loading the elements basic parameters first like color, background color then fonts, font size, line height then width, height and then margins, padding and then borders, transitions, shadows and then position, clip and display. I got this from the inspect element pane and how different browsers were ordering my css. If you have them out of order, safari would reorder them according to their spec and I had found that most other browsers treated this the same way and reordered them similarly. So it is a yes and no answer with a personal preference included. Try it for yourself. Put them in the order you want and see how Safari or chrome or firefox reorder them respectively. For example: div{ width: 100%; margin: 10px 20px; padding: 0; position: relative; display: block; } Best, Karl DeSaulniers Design Drumm http://designdrumm.com > On Oct 13, 2016, at 10:32 PM, Philippe Wittenbergh <e...@l-c-n.com> wrote: > > >> On Oct 14, 2016, at 12:13 PM, Tom Livingston <tom...@gmail.com> wrote: >> >> Curious.
