I have added 2 buttons to show and hide the Loading text. I want the "Loading Text" itself to always be positioned in the middle of the "kl" div, even on scroll/resizing of window.
Even with top/left = 50% and position=absolute, the text is not centered (mainly on resizing). What do I need to change to get it centered properly.

just i added position:relative to outer and inner div to position:fixed
