jquery background image fade -

-

i using jquery load ina background image fills page width / height. have following in head:

$(document).ready(function() {     $('body').css({     'background-image' : 'url({html_base}images/backgrounds/randoms/{back_img})',         'background-repeat' : 'no-repeat',         'background-position' : 'center top',         'background-attachment': 'fixed',         'background-size': '100% 100%',     });     $('#home-promo').innerfade({          speed: 'slow',          timeout: 5000,          type: 'sequence',          containerheight: 'auto'     });      $('.model-search').innerfade({          speed: 'slow',          timeout: 5000,          type: 'sequence',          containerheight: '393'     });  });

this works fine , can seen @ http://projects.snowshtechnologies.com/golden_dragon/home/

i want bg image fade in black background colour. have looked @ few other threads on stack suggest not possible body element defined in css, in scenario bg image being loaded in jquery. how go adding fade in code bring image in nice fadein?

you can set body background-color black , make element div, position fixed , fade in, element should fill entire width , height of browser's viewport.

delphi - When I encode/decode SMS PDU (GSM 7 Bit) user data, do I need prepend the UDH first? -

while can encode , decode user data part of sms message when udh not present, i'm having trouble doing when udh is present (in case, concatenated sms). when decode or encode user data, need prepend udh text before doing so? this article provides encoding routine sample compensates udh padding bits (which still don't understand) doesn't give example of data being passed routine don't have clear use case (and not find decoding sample on site): http://mobiletidings.com/2009/07/06/how-to-pack-gsm7-into-septets/ . so far, have been able results if prepend udh user data before decoding it, suspect coincidence. as example (using values https://en.wikipedia.org/wiki/concatenated_sms ): udh := '050003000302'; encoded_user_data_part := 'd06536fb0dbabfe56c32'; // padding, evidently decodeduserdata := decode7bit(udh + encoded_user_data_part); writeln(decodeduserdata); output: "ß@ø¿Æ @hello world" encodeduserdata := encode7bit(decodeduse...
