jquery - Position Div below window height -

-

lets see below example

<div>main content<br><br>main content fills windows height</div> <div id="belowcontent">content show below windows height</div>

i tried below

$("#belowcontent").css("margin-top", $(window).height());

but problem here div using height previous div,not browser top.i tried position absolute too.still not working.

p.s: if pure css method , thats advantage

absolute positioning

you use absolute positioning top declaration. in case i've set top 100vh place below screen height.

html,  body {    margin: 0;    padding: 0;    background: lightgray;  }  .main {    background: cornflowerblue;  }  #belowcontent {    position: absolute;    top: 100vh;    background: tomato;  }
<div class="main">main content    <br>    <br>main content fills windows height</div>  <div id="belowcontent">content show below windows height</div>

relative positioning

if don't want use positioning, may able use (instead) min-height property on main div:

html,  body {    margin: 0;    padding: 0;  }  .main {    min-height: 100vh;    background: cornflowerblue;  }  #belowcontent {    background: tomato;  }
<div class="main">main content    <br>    <br>main content fills windows height</div>  <div id="belowcontent">content show below windows height</div>
