html - Opacity only on ul not on li css -


this question has answer here:

i have list height of 300px , want background have opacity. list items have stay same (opacity 1). how can this? code:

html:

<div class="dropdown">                     <span class="notif">2</span>                     <ul class="dropdown-menu">                         <li><a href="#"><span>elisadehasque</span> liked story in <span>disneyland paris</span><span class="done">x</span></a></li>                         <li><a href="#"><span>petyana</span> started following you<span class="done">x</span></a></li>                     </ul>                 </div>

css:

    .dropdown .dropdown-menu {     position: absolute;     top: 100%;     display: none;     margin: 0;     margin-left: -100px;      padding: 0;     height: 300px;     width: 250px;     background-color: #fff;     z-index: 10;     opacity: 0.8; }  .dropdown-menu li {     z-index: 999999;     opacity: 1; }

use rgba:

.dropdown .dropdown-menu {     background-color: rgba(255, 255, 255, 0.8); }

from documentation:

rgba()

colors can defined in red-green-blue-alpha model (rgba) using rgba() functional notation. rgba extends rgb color model include alpha channel, allowing specification of opacity of color. means opacity: 0=transparent; 1=opaque;

rgba(255,0,0,0.1) /* 10% opaque red */

rgba(255,0,0,0.4) /* 40% opaque red */

rgba(255,0,0,0.7) /* 70% opaque red */

rgba(255,0,0, 1) /* full opaque red */

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
