html5文字不占据占位符,HTML5 textarea占位符未出现

I cannot figure out what is wrong with my markup, but the placeholder for the text area will not appear. It seems as though it may be covered up with some blank spaces and tabs. When you focus on the text area and delete from where the cursor puts itself, then leave the text area, the proper placeholder then appears.
