html - Positioning relative to table-cell -


the effect of 'position:relative' on table-row-group, table-header-group, table-footer-group, table-row, table-column-group, table-column, table-cell, , table-caption elements undefined.

source: http://www.w3.org/tr/css21/visuren.html#propdef-position

is there idea position relative have set display property table-cell using :before or :after selector?

.someclass{display: table-cell; position: relative; z-index: auto;}  /*this won't work*/

there kinda hacky way without additional elements using negative margin:

http://jsfiddle.net/cvyxm/1/

td span {     display: block;     width: 10px;     height: 10px;     margin: -5px;     background: red;     position: relative;     top: -5px;     left: -5px; }

you position element relative cell, while eliminating dimensional impact on other elements adding negative margins on sides in correlation elements own dimensions.

problem here positioned element must have fixed dimensions (can't work percentage negative margin because depends on outer element).

the other, more common solution add additional wrapper element inside cell width position relative , position other child elements absolute wrapper.

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).
