See this:
Use font-family, not font-style.
oooops im supra bad at css
It still doesn't work for me.
(almost) two years later and i finally updated it. it now actually writes in verdana bold, just like Snap!
Amazing work!
You may want to set the font to Verdana, Arial, sans-serif, because if a user doesn't have Verdana installed, it'll then go to Arial, then the browser default sans-serif font.
can u next work on cmd block shapes?
whar
Why did you tag me? Was it because of my set of blocks?
Yeah. They're in the menu now, right?
Yes, they are.
i have updated it to version v0.n+2
That's basically the same as calling it "ver $$4x^y + 8 = 13,\text{ if } y = 3$$"
ah, yes, i love version $$\sqrt[3]{5\over4}$$
Are you trying to recreate snap!?
not in full, just the block-drawing
btw to all who mentioned it, i'm currently working on... command blocks!
I saw you matched the striped pattern of the IDE recently (I don't know how recently however). I have to say, nice work!
If I may add a suggestion, it would be cool to also add predicates (I think you're already planning those) and arrow reporters from Snavanced!. Be happy I remembered the mods. 
at some point certainly
thanks. it wasn't really hard--probably the hardest part was either getting it to draw the lines in the right spots or figuring out how the js code for it in Snap! works
