html - Freeze Screen w/ Overlay if JavaScript isn't enabled -


i'd darken , lock page (prevent clicking / scrolling) , have white text saying user doesn't have javascript enabled.

i know proper thing have gracefully degrade when there isn't javascript- don't want go route right now.

<noscript> <div id="nojs-overlay"> please enable javascript view site<br> <a href="instructions.html">instructions on how enable javascript</a> </div> </noscript>

the above example loads overlway div in case javascript not enabled. selected answer cause flicker or delay on slow devices.

make sure style nojs-overlay div (or series of divs) overlay complete screen.
