css - CSS3 nth-of-type combined with a class -

-

i have page wrapper class called .j-l-page-wrapper. have section wrapper class called .j-v-section-wrapper. each section wrapper in page wrapper have alternating background colors. have used following css:

div.j-l-page-wrapper div.j-v-section-wrapper:nth-of-type(even) {     background-color: @j-var-color-section-wrapper-bg-mod1; }  div.j-l-page-wrapper div.j-v-section-wrapper:nth-of-type(odd) {     background-color: @j-var-color-section-wrapper-bg-mod2; }

along html

<div class="j-l-page-wrapper">     <div class="j-v-section-wrapper"></div>     <div class="j-v-section-wrapper"></div>     <div class="j-v-section-wrapper"></div>     <div class="j-v-section-wrapper"></div> </div>

however, no alternating background coloring applied, leading me think have not applied correct selector.

how say, using css3, apply even/odd based background coloration div of 1 type containing div of type? put way, if html were:

<div class="j-l-page-wrapper">     <div class="j-v-section-wrapper"></div>     <div class="something-else"></div>     <div class="j-v-section-wrapper"></div>     <div class="j-v-section-wrapper"></div>     <div class="j-v-section-wrapper"></div>     <div class="something-else"></div> </div>

... still want 4 divs of specified type have alternating colors.

to put simply, second markup configuration can't have desired behaviour css.

the div.your_class:nth-of-type() counts div elements of same level. adding class selecor makes sure style applied elments class keeps counting divs have same level.

workaround :

you can replace tags class .something-else other tag (for example <span> element) work desired :nth-of-type()

demo

html :

<div class="j-l-page-wrapper">     <div class="j-v-section-wrapper"></div>     <span class="something-else"></span>     <div class="j-v-section-wrapper"></div>     <div class="j-v-section-wrapper"></div>     <div class="j-v-section-wrapper"></div>     <span class="something-else"></span> </div>

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

cgi - How do I interpret URLs without extension as files rather than missing directories in nginx? -

-
so i'm trying install zoneminder , have run under nginx, has few compiled files need run using fast-cgi. these files lack extension. if file has extension, there no issue , nginx interprets file , return 404 if can't find it. if has no extension, assume it's directory , return 404 when can't find sort of index page. here have now: # security camera domain. server { listen 888; server_name mydomain.com; root /srv/http/zm; # enable php support. include php.conf; location / { index index.html index.htm index.php; } # enable cgi support. location ~ ^/cgi-bin/(.+)$ { alias /srv/cgi-bin/zm/; fastcgi_pass unix:/run/fcgiwrap.sock; fastcgi_param script_filename $document_root/$1; include fastcgi.conf; } } the idea is, under cgi-bin directory goes through fastcgi pipe. any idea on howi can fix this? upon closer inspection, realized zoneminder has 2 cgi sc...
