Strange behavior, writing right to left

Hello, something strange happened to my app, and i can't fogure out whats it.

for example when i type something in form field im wrting from right to left...
when i have horizontal unordered list , the first element is most to
the right too :confused:

does that ring a bell to anyone?

Yes, this is CSS/HTML/Browser issue but not actually Rails' engine

Idd, it happens when i apply blueprint css, but its vanilla version,
same i used with many applications so far - and none gave such weird
results.
