[SOLVED] stick content at the bottom of the page

stick content at the bottom of the page

My problem:

I designed single page. Header, content(section and aside) and footer.

Footer and header are sticky.

I want content to stick to the end of page and above footer.

Guide me, please.

Solution

Are you implying something like this. In this example. no matter what screen size your content will always stick to the footer, even if there is a single line in it.

*{
  box-sizing: border-box;
}
body, html{
  height: 100%;
  width: 100%;
  margin: 0;
}
body{
  display:flex;
  flex-direction: column;
}
#container
{
    margin: 0 auto;
    width:90%;
    background-color: white;
    border: 2px solid black;
    flex-shrink:0;
    flex-grow:1;
    display:flex;
}
.header,.footer
{
    margin: 0 auto;
    width:100%;
    text-align: center;
    height:1.5em;
    background-color: white;
    border: 1px solid black;
    flex-shrink:0;
    background-color:green;
  color:white;
}
.col {
    height:90%;
    flex-shrink:0;
    flex-grow:1;
    margin:0 2% 0 2%;
}

<div class="header">
  Header here
</div>
<div id="container">
  <div class="col">
    test column 1
    <p>

    </p>

  <div class="col">
