For the CSS size:
Thousands of shops in germany are running this.
But, for productive environment, the file is compressed down to around 300kB
later in the shop system. Still has lines of >100kB I think...
Obviously it is OK, that there are limits in an editor.
The only thing is, that it should better not result in a crash or an endless
loop.
That would be nice!
