Place holder not display

I just starting to use this library in my project, I seem can not to use setPlaceholder method, It not error or something, but It won't show in the Rich Editor.

Same happening with me, if we hard code string then only it works, if we set using a string variable that time its not working.

I have the same question, then I look his code found it has double "}" in the style.css file in the last,so it not work, it should be like this
#editor[placeholder]:empty:not(:focus):before { content: attr(placeholder); opacity: .5; }
so you can copy it to the new CSS file,and use the richEditor.loadCSS("xxx.css"); it worked.
