javascript - How can I get jQuery.css() to trump a stylesheet? -


i have been working on page , programmatically set css properties on cover slideshow according how screen real estate there is. if page less 1 boundary number, don't want activate slideshow. if page has width greater boundary number, less threshold, want have slideshow shrink, , shrink more smaller sizes. finally, if greater both, horizontally center slideshow in logical container.

the source @ http://jonathanscorner.com/blacksmiths-forge/experimental.html has:

<iframe id="slideshow" border="0" frameborder="0" frameborder="no" style="display: none;" width="318" height="424" src="/book_covers.cgi?width=318" />

the css @ http://jonathanscorner.com/css/combined.css has:

#slideshow     {     height: 424px;     position: fixed;     top: 240px;     right: 190px;     width: 318px;     }

and javascript, @ http://jonathanscorner.com/js/combined.js:

if (jquery(window).width() > 1200)     {     if (jquery(window).width() > 1300)         {         var width = min(jquery(window).width() - 1200, 318);         document.getelementbyid('slideshow').src = "/book_covers.cgi?width=" +  width;         document.getelementbyid('slideshow').width = width + 'px';         document.getelementbyid('slideshow').width = width;         jquery('#slideshow').css('right', jquery(window).width() - 1200 - 318);         jquery('#slideshow').css('display', 'block');         }     }

the mental model walked in jquery.css() trump card, , in permutations i've tried far, i've never been aware change has been made jquery.css.

i tried using e.g. jquery('#slideshow').css('display', 'block !important').

is there way use jquery (or javascript alone) set properties in way stick?

(what wrong initial understanding, , truth can , can't done programmatic setting of dom node styles , properties?)

you haven't closed iframe tag, combined.js never loaded. iframe's aren't self-closing tags, require opening , closing tag.

<iframe></iframe>

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
