html - Relative Positioned Child in Absolute Positioned Child... (Help) -


all right, i'm trying understand how positioning code works , make responsive in website. every bug i've come across i've been able fix myself through research online , constant staring (lol). however, i've come across rather irritating issue...

the issue -i have div positioned relative (id: news_content) , within div positioned absolute (id: page). when try move news_content using positioning commands top , left, left 1 reacting. while top command isn't moving news_content @ all.

/*global*/  body {      margin:0;      padding:0;  }  div {      margin:0;      padding:0;      top:0;      left:0;      bottom:0;      right:0;  }  table {      margin:0;      padding:0;      border-spacing:0;  }    /*global divs*/  #page {      position:absolute;      top:0;      bottom:0;      left:0;      right:0;  }  #nav_main {      background-color:black;      width:100%;      height:14%;      position:fixed;      z-index:0;  }        /*navigation*/  #nav_content {      background-color:gray;      width:12.5%;      height:86%;      position:fixed;      top:14%;      z-index:-1;      }      #nav_side_container {          background-color:black;          width:60%;          height:93%;          position:relative;          top:3.5%;          left:18.75%;          }      #nav_side {          background-color:red;          width:75%;          height:93%;          position:relative;          top:3.5%;          left:12.75%;          }          #nav_side table {              width:100%;              height:100%;              font-family:'playball';              font-size:1.25em;              font-weight:bold;              text-align:center;              }              #nav_side table td {                  width:100%;                  height:33.33%;                  border-top:0.1em solid black;                  }    /*news*/  #news_content {      background-color:red;      width:87.5%;      height:86%;      position:relative;      top:14%;      left:12.5%;      z-index:-2;      }  /*  #news {      background-color:black;      width:10em;      height:10em;      position:relative;      left:10em;  }  #news_main {      background-color:blue;      width:10em;      height:10em;      position:relative;  }  #news_side {      background-color:green;      width:10em;      height:10em;      position:relative;  }    /*articles*/  #articles_content {      background-color:blue;      width:87.5%;      height:86%;      position:relative;      left:12.5%;      z-index:-2;      }    /*future plans*/  #future_content {      background-color:green;      width:87.5%;      height:86%;      position:relative;      left:12.5%;      z-index:-2;      }

..

-no idea problem truthfully... knowledge on how relative , absolute positioning wrong or code being complete haywire.

it's because #page id doesn't have height on it. if give height: 100%;, should it.

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
