css - HTML background-image not showing on screen -


i trying create full width image above nav bar, cant image show on screen. here simple html:

<html>   <body>     <div class="wrapper" />   </body> </html>

and css:

.wrapper {   background-image: url(../assets/bridge.jpg);   background-repeat: no-repeat;   background-size: 100%;   width: 100%;   height: 100%; }

i see jpg made browser , can click on in resources, there no problem path. screen still blank , showing nothing. awesome.

this because height:100% functionally useless, , div resultingly has no height.

if give div fixed height, image should appear expected.

alternatively if want background image apply background of page, can apply <html> element , avoid whole wrapper, 100% debacle.

html {      background-image: url(../assets/bridge.jpg);      background-repeat: no-repeat;      background-size: 100%; }

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).
