opacity in a speech bubble in css -


i'm using http://nicolasgallagher.com/pure-css-speech-bubbles/demo/ speech bubble, want inside of bubble , triangle have background opacity of 0.7.

for background i'm using: background-color: rgba(0, 0, 0, 0.7);

and triangle: opacity:0.7;

but seems triangle , background doesn't have same opacity, put higher z-index triangle doesn't help.

my full css are:

.infobubble {     font-family:arial;     font-size:12px;     color:#ffffff;     display: inline-block;     position: absolute;     padding:6px;     background-color: rgba(0, 0, 0, 0.7);     background:-moz-linear-gradient(#000, #000);     background:-o-linear-gradient(#000, #000);     background:linear-gradient(#000, #000);     -webkit-border-radius:7px;     -moz-border-radius:7px;     border-radius:7px;     box-shadow: 1px 1px 3px black; }  .infobubble:after {     content:"";     position:absolute;     bottom:-6px;     left:20px;      opacity:0.7;     border-width:6px 6px 0;      border-style:solid;     border-color:#000 transparent;     display:block;      width:0; }

here jsfiddle: http://jsfiddle.net/malamine_kebe/qzqzw/

thanks helping!

it's because opacity of main bubble not being applied - 3 styles:

background:-moz-linear-gradient(#000, #000); background:-o-linear-gradient(#000, #000); background:linear-gradient(#000, #000);

are overwriting 

background-color: rgba(0, 0, 0, 0.7);

also if use 

-moz-box-shadow: 1px 1px 3px rgba(0,0,0,0.7); -webkit-filter: drop-shadow(1px 1px 3px rgba(0,0,0,0.7)); filter: drop-shadow(1px 1px 3px rgba(0,0,0,0.7));

instead of 

box-shadow: 1px 1px 3px black;

it make shadow work properly

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).
