Recognize " Html Volt "

• The red line area is real html button size, the purple line area is the button size what I guess.
  when the mouse cursor go to some area that the web html will show result not what I want. for example,  the cursor stop between any two button center area.
  like use mouse go to play "電流イライラ棒", you need to control your cursor carefully.
