A utility for converting font-size css styles from px to rem units.

Determining a unit of measurement to size our text can be a topic of heated debate, even in this day and age. Unfortunately, there are still various pros and cons that make the various techniques less desirable. It's just a matter of which less-desirable is most desirable. There are two main techniques that are extolled: Size with px Size with em Let's review these two approaches before I reveal the magical third.

Em Calculator is a small JavaScript tool which helps making scalable and accessible CSS design. It converts size in pixels to relative em units, which are based on a text size.

So for the H3 example: 9/24 = .375

Em Calculator estimates Em size equivalent to px size. Could become useful since more standardistas are adpoting use of Em sizing (vs. px sizing) to define the max width of their layout, a technique which I intend to investigate more thoroughly.

J'ai essayé de faire un truc qui ressemble vaguement à ce que demande Emmanuel Clement dans son billet sur le coup du 62.5%, en python. C'est bourrin, ca a vaguement l'air de marcher, mais j'ai pas plus testé que ca. Feedback welcome, parceque moi c'est un truc dont je me fiche un peu à la base (je suis farouchement contre le principe meme de toucher à la taille initiale du body, étant moi meme réglé sur une taille de police de base dans mon navigateur de 12px et non 16, valeur par défaut utilisée un peu partout), donc je n'ai aucune idée de si ca correspond ou non à ce qui est demandé
