After finished the standard “Resposive Web Design” I started the beta version.
Time after time, I encontered various error that I solved just refreshing the page a few times.
But now, I have problems with the “Learn CSS Transforms by Building a Penguin”: it happened yesterday and today too, just right now: even if I write down the right code, it says that I wrong (like in the picture - that is just an example, I had the same problem here and there in the previous section).
No difference using firefox, chrome or safari: it behaves the same.
Please, could you take a look at this curriculum?
It’s a pity it doesn’t work properly!
Here a pic of the situation when it gives me the error.
