html - Centering an CSS arrow -


i've used following code create myself arrow,

.arrow-divider{     height:12px;     width:12px;     transform:rotate(-45deg);     border-right:2px solid white;     border-bottom:2px solid white; }

whenever try center using margin:0 auto not center because want half of right side of box centered, centers whole box, how fix this?

i'm stuck on following code

<div class="box">    <div class="center-divider"> </div>    <div class="arrow-wrapper">    <div class="arrow-divider"></div>     </div>  </div>  .box{   position:relative;   background:orange;   width:100%;   height:50px;   text-align:center;   line-height:50px; }  .arrow-wrapper{   display:inline-block; }  .center-divider{   position:absolute;   width:6px;height:100%;   background:red;   left:0;right:0;   margin:auto; } .arrow-divider{   height:12px;   width:12px;   transform:rotate(-45deg);   border-right:2px solid black;   border-bottom:2px solid black; }

i've included following demo: jsfiddle

last word, i'm not looking use flexbox , it's align-items , justify-content feature.

edit: why downvote?

since arrow divider fixed width/height of 12px... why not subtract half of it: margin-left:-6px ?

.arrow-divider{   height:12px;   width:12px;   margin-left:-6px;   transform:rotate(-45deg);   border-right:2px solid black;   border-bottom:2px solid black; }

here updated fiddle.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
