How to limit max width and height to screen size in CSS?

I'm trying to make a php gallery and thats why I need a good Mask, where the pictures later can be shown. I want the Mask not to be bigger than screen-size. I mean, there must be no scrolling and the whole <body> needs to have just the width and height of the browser windows, so that every child object in <body> is limited to the frame-size of the browser and will be shrunk down if it overflows. I've tried with max-width and max-height on the <body>, but it doesn't work.

Here are the contents of my index.html file: 

<!DOCTYPE html>
<html>
<head>
  <link rel="stylesheet" type="text/css" href="style.css">
</head>
<body>
  <div id="mother">
    <div id="header">
      <div id="back-link">
        <a href="../">Home</a>
      </div>
      <div id="prev">
        <a href="">next picture</a>
      </div>
      <div id="next">
        <a href="">previous picture</a>
      </div>
      <div id="headline">
        <p class="h2">Our Galery</p>
      </div>
    </div>

    <!-- Content -->
    <div id="container-bild">
      <img src="./bilder/P1130079.JPG" id="img-bild" />
    </div>
  </div>
</body>
</html>

Here are the contents of my style.css file:

body {
  max-width: 100%;
  max-height: 100%;
}

/* mother-container */
div#mother {
  max-width: 100%;
  max-height: 100%;
  margin: auto;
}

/* main-container */
#container-bild {
  max-width: 100%;
  max-height: 100%;
}

/* picture in main-container */
#img-bild {
  max-width: 100%;
  max-height: 100%;
  border: 1px solid #280198;
}

Here is a screenshot of what it looks like:

This works great. This will keep your image from growing too large width wise and also keep its proportions. 

img {
    max-width: 100%;
    height: auto;
}

To set the height and width to be 100% of the window (viewport) size, use:

height: 100vh;//100% view height
width: 100vw;// 100% view width

.

div {
  background-color: blue;
  height: 100vh;
  width: 100vw;
  position: absolute;
  top: 0;
  left: 0;
  color: white;
}
<div>some content here</div>

My CSS solution is:

position: absolute;
width: 100%;
height: 100%;
overflow: hidden;

As a reminder for my future self:

.book {
    margin: auto;
    width: 100vh;
    max-width: 100vw;
    min-width: 500px;
}

Though this is completely unrelated, for links, you might want to use something like:

a[href^="#"] {
    text-decoration: none;
    color: black;
    background: url("http://www.yaml.org/spec/1.2/term.png") no-repeat bottom right;
}
a[href^="#"]:hover {
    text-decoration: underline;
    color: blue;
    background: none;
}

Try:

html,
body {
  height: 100%;
}

body {
  overflow: hidden;
}

Do you know how many child elements will be in your gallery? If the number of elements is static, you could simply set their dimensions in CSS using vw and vh units. No JavaScript involved, and the elements would never be able to overflow your body.

I'm not sure if this is possible with css, it could be. I have solved similar issue with javascript:

window.top.innerHeight;

gets the available height, excluded menubars etc. of the borwser. See how I did for the height, my issue was that the footer should be at the bottom even if content was empty-> 

<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>C-Driver Manager</title>
<meta name="keywords" content="Aygit,Device,Driver,Surucu,Download,Indir,yedekle,Unknown,Bilinmeyen,Backup,Back-up,stuurprogramma,apparaat,windows,w7,w8,w10,multilanguage,tool,free,gratis,ucretsiz">

        <div class="divtopcontainer">
            <div class="divlogo">

            </div>
            <div class="divHmenu">
                <style>
    .mnuHorizontal
    {
        list-style:none;
    }
    .mnuHorizontal li
    {
        float:left;
    }

    .mnuHorizontal .activemnu a,.mnuHorizontal li a:hover
    {
        background:#00B7EF;
        border-radius:5px;
        color:white;
    }


    .mnuHorizontal li a
    {
         display:inline-block;
         text-decoration:none;
         padding:5px 12px;
         text-align:center;
         font-weight:bold;
         color:#020042;
    }

    </style>

<ul class="mnuHorizontal">

    </div>
</body>
    <script>
        for (i=0;i<document.getElementsByClassName('mnuHorizontal').item(0).children.length; i++)
        {
            if (document.getElementsByClassName('mnuHorizontal').item(0).children[i].id ==
                "index.php")

            {
                document.getElementsByClassName('mnuHorizontal').item(0).children[i].className = 'activemnu';
            }
            else
            {
                document.getElementsByClassName('mnuHorizontal').item(0).children[i].className = '';
            }
        }

        resizecontainer();

        function resizecontainer()
        {
            avh     =   window.top.innerHeight;
            dbh     =   document.getElementsByClassName('divbottom').length *
                        document.getElementsByClassName('divbottom').item(0).clientHeight;

            dbt     =   document.getElementsByClassName('divtop').length    *
                        document.getElementsByClassName('divtop').item(0).clientHeight;

            dbbl    =   document.getElementsByClassName('divblueline').length   *
                        document.getElementsByClassName('divblueline').item(0).clientHeight;

            decrh = dbh + dbt + dbbl;

            document.getElementsByClassName('divcontainer').item(0).style.minHeight = (avh - decrh) + 'px';
        }
    </script>
</html>

look for this function inside the example above ->

function resizecontainer()
        {
            avh     =   window.top.innerHeight;
            dbh     =   document.getElementsByClassName('divbottom').length *
                        document.getElementsByClassName('divbottom').item(0).clientHeight;

            dbt     =   document.getElementsByClassName('divtop').length    *
                        document.getElementsByClassName('divtop').item(0).clientHeight;

            dbbl    =   document.getElementsByClassName('divblueline').length   *
                        document.getElementsByClassName('divblueline').item(0).clientHeight;

            decrh = dbh + dbt + dbbl;

            document.getElementsByClassName('divcontainer').item(0).style.minHeight = (avh - decrh) + 'px';
        }
