html5 - Html 5 Specification -


this question has answer here:

in html5 should use <br> or <br />? same question <div>.

i have noticed using breaks rendering in ie 10 causes miss calculation of height unless window re-sized. (hidden areas seem causes not figured out specific html yet)

if div's should closed </div> notice lot of library's presuming allowed (clearing floats common 1 <div class="clear" />)

divs not self closing. <br /> xhtml. i'd bet aren't serving pages xhtml don't that. using self-closing tags in html, break show, forces browser treat markup error , has guess @ meant. it's called "tag soup". while browsers pretty job @ that, shouldn't more entering wrong code programming language , hoping software handles mistake.

validate markup , see validator says. read spec see how such things written.

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).
