Subject: Set hint css vie web content manager #349.
X-Git-Url: https://git.owens.tech///git?a=commitdiff_plain;h=3b9bf50b4cbcf5b4b78cec47fe2454ba6493aa59;p=vimb.git

Set hint css vie web content manager #349.

Add the hint css direct to webkit instead of manipulating the DOM to add
a style node. By the way the default style was removed from config.def.h
into src/scripts directory so that the css is minified during
compilation.
