css - Website height > 100% -


i started website yesterday, trying out different things can apply them later on when start making websites companies etc. anyway, wondering wrong code. want website 100% in height. got sorted out @ first, when applied transparant background image div 'content' website's height wasn't 100% anymore. (you need scroll bottom of page). me solving problem? appreciated! (i looked tons of earlier asked questions, did not have answer looking for.)

html {            background: url('http://i.imgur.com/dbg9grg.jpg') no-repeat center center fixed;            -webkit-background-size: cover;           -moz-background-size: cover;           -o-background-size: cover;           background-size: cover;           height: 100%;         }  body {     margin: 0;     padding: 0;     height: 100%;    }  #header {     width: 100%;     height: 75px;     background-color: rgba(0, 0, 0, 1);   }  #logo {     width: 25%;     height: 75px;     float: left; }  #content {     width: 100%;     height: 100%;     background-image: url('http://i.imgur.com/rm9fzh0.gif');     background-repeat: repeat;     margin: auto;     min-height: 100%; }  #song {         position: absolute;         bottom: 0;         left: 0;         margin: 20px;    }

and html: (if required)

<div id="header">     <div id="logo">     <img src="images/logo.png" href="index.html" />     </div> <!-- close logo --> </div> <!-- close header -->  <div id="content"> <div id="nav">     <ul>     <li><a href="visit.html">visit tromsø</a></li>     <li><a href="about.html">about us</a></li>     <li><a href="contact.html">contact us</a></li>     </ul> </div> <!-- close nav --> <div id="song">  <audio autoplay="autoplay" controls="controls">      <source src="music.ogg" />      <source src="music.mp3" />   </audio>   </div> <!-- close song --> </div> <!-- close content -->

the css pasted down there isn't whole thing, sure 'nav' not have effect on height of page. in advance!

that's because child element larger body.

your #content has height: 100%, not it's not div in body has margins , paddings.

when set height: 100% of child element, it's height equal height of parent (before applying margins , paddings). #content @ least tall body, , therefore whole page taller that.

you need fix accordingly.

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).
