fix search box position

[shoyan]

検索ボックスの場所がずれていたので修正しました。 Chrome, Firefox, Safariで確認しています。

I'm currently using this as div style with the new layout on github:

display:inline-block; float:right;

Doesn't hard-code anything like 435px but I also haven't tested with firefox or safari.

It's correct.
