html - Implement z-index to the particular div element -


hi wanted put z-index ensure "event today" behind element(collapse). here code below....

    <div id="infobox" class="collapse"  >                 <table id="attacks" class="display" cellspacing="0" width="100%"  >                     <thead style="z-index:10">                         <tr>                             <th>time</th>                             <th>attacker</th>                             <th>target</th>                         </tr>                     </thead>                     <tfoot>                         <tr>                             <th>time</th>                             <th>attacker</th>                             <th>target</th>                         </tr>                     </tfoot>                 </table>             </div>  <div class="toolbar-left2 noselect" >         <table>             <tr>                 <td style="color:white;background-color:#000000;">events today: <font></font></td>                 <td id="totalattack" style="color:white;background-color:#000000;">0      </td>                 <td align="right"id="todaytime" style="color:white;background-color:#000000;">current time</td>             </tr>         </table>     </div>

my question how ensure clock element behind element contains class collapse...please me thank you.

your z-index: -10 does indeed make element appear behind other elements.

only content 'positioned', such position: absolute, position: fixed or position: relative respect z-index. note default position: static not obey z-index.

also, keep in mind default z-index 0. although element appear on top of elements such <body> , <html>, behind them.

here's working example, showcasing element gets hidden behind red square:

#sample {    position: absolute;    top: 0;    left: 0;    width: 100px;    height: 100px;    background: red;  }
<div class="toolbar-left2 noselect" style="z-index:-10">    <table>      <tr>        <td style="color:white;background-color:#000000;">events today:          <font></font>        </td>        <td id="totalattack" style="color:white;background-color:#000000;">0 </td>        <td align="right" id="todaytime" style="color:white;background-color:#000000;">current time</td>      </tr>    </table>  </div>    <div id="sample"></div>

in example, you'll need add position both .collapse , .noselect, , make sure give .collapse higher z-index .noselect. in following example, i've changed text red illustrate this:

.collapse {    position: relative;    z-index: 10;    color: red;  }    .noselect {    position: absolute;    top: 0;    left: 0;  }
<div id="infobox" class="collapse">    <table id="attacks" class="display" cellspacing="0" width="100%">      <thead style="z-index:10">        <tr>          <th>time</th>          <th>attacker</th>          <th>target</th>        </tr>      </thead>      <tfoot>        <tr>          <th>time</th>          <th>attacker</th>          <th>target</th>        </tr>      </tfoot>    </table>  </div>    <div class="toolbar-left2 noselect">    <table>      <tr>        <td style="color:white;background-color:#000000;">events today:          <font></font>        </td>        <td id="totalattack" style="color:white;background-color:#000000;">0 </td>        <td align="right" id="todaytime" style="color:white;background-color:#000000;">current time</td>      </tr>    </table>  </div>

hope helps! :)

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
