html - Some selectors doesn't work for me -

-

i writing selectors didn't work me.

html code :

<h2 rel="singer-connector-cricketer">shoaib chikate</h2> <h2 rel="dancer-build-tester">ashok dongare</h2>

css code:

h2[rel|="connector"]{     color:blue; }

css tricks attribute

similarly :matches() selector not working although i'm using higher version of chrome (version 32.0.1700.77).

html code:

<div id="matcher">         <p>matched</p>         <h1>not</h1>         <h2>matched</h2>         <h3>not</h3> </div>

css code:

#matcher :matches(p,h2){     color:purple; }

how selectors work?

css tricks selectors- :matches()

jsfiddle

h2[rel|="connector"] looks attribute value starts "connector" followed hyphen. not attribute value has word "connector" anywhere among set of hyphenated words — value must start given string.

since 2 elements given have rel attributes values start "singer-" , "dancer-" respectively, neither of them matched.

i'm not aware of version of chrome supports :matches() yet. latest stable version (34.x of writing) still support :-webkit-any(), however.

of course, should go without saying shouldn't use :-webkit-any() , rest of prefixes in production code, because css error handling rules mean using in current prefixed state causes have write duplicate rules each prefix, runs counter intended purpose. see this answer example. can test these new selectors want, there's little gain trying use them in production while support them still poor.

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
