Small news to share my amazement for CSS: changing the design of my website took me around 15 minutes (based on a Ganesh Gunasegaran‘s initial template). The content didn’t change. Only the way “semantic elements” are displayed was changed (+ some minor adaptations, of course). Et voilà ! 🙂
Next step: adapt this blog design to my website design (I won’t do it right now).

Oh, btw, today was “CSS Naked Day” (http://naked.dustindiaz.com/), I didn’t know it.
