The bottom of border missing in my webpage

Question

I am attaching the html and css code here

The problem is, even after using overflow: scroll property in css, the bottom of the page isn't visible unless I resize the window to some weird proportion. One more problem is, not just the border. everything below that is not visible and I cant scroll below to see it. Giving scroll property to the div container destroys the image positions.

body {
  background-color: #001126;
  margin: 0;
  overflow: scroll;
}

.container {
  border-style: solid;
  border-color: white;
  margin: 70px;
  color: white;
  padding: 80px;
  font-size: 30px;
  position: fixed;
}

.menu {
  top: -40px;
  left: -40px;
  position: absolute;
}

.social {
  margin-top: 5%;
  position: absolute;
}

.icons;
{
  position: absolute;
}

#img {
  padding-left: 20px;
  padding-bottom: 10px;
}

  <div class="container">
    <div class="contents">
      <p id="text">It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content

Answer 2

This was beacuse you gave position: fixed to the container.

body {
  background-color: #001126;
  height: auto;
  margin: 0;
  overflow: scroll;
}

.container {
  border-style: solid;
  border-color: white;
  height: 100%;
  margin: 70px;
  color: white;
  padding: 80px;
  font-size: 30px;
}

<div class="container">
  <div class="contents">
    <p id="text">some large text</p>
  </div>
  <div class="menu"><img src="icon.png" style="height: 50%;width:50%"></div>
  <div class="social">
    <div class="icons">
      <img src="fb.png" style="height: 8%;width:8%" id="img">
      <img src="insta.png" style="height: 8%;width:8%" id="img">
      <img src="tw.png" style="height: 8%;width:8%" id="img">
      <img src="u.png" style="height: 8%;width:8%" id="img">
      <img src="vid.png" style="height: 8%;width:8%" id="img">
    </div>
