html - Page height to 100% of viewport?

I'll start by saying that I am very very new to web development as a whole and that this is my very first responsive site so please be gentle and bear this in mind, I am the definition of the word noob at this stage. Having searched for an answer for a while and having no luck I'm hoping that someone here could help me out.

I'm trying to make a homepage for this website. The design is simply a block down the left hand side of the page showing the logo at the top and then a series of links underneath, all of which is on the same background. To the right of this is one big image which fills the rest of the screen. I want the whole page to fill the browser window of whatever device it is viewed on so absolutely no scrolling is necessary, i.e. width and height both 100% of the viewport. The width of the page is giving me no grief at all, sweetly adjusting to different screen sizes as I want it, with the sidebar at 20% of the width and the main image at 80%.

The height is a different story however. I can't seem, in any combination of CSS I've tried so far, to be able to get the height to behave at 100% of the viewport. Either the sidebar is too short and the main image is too long or both are too long etc etc. The main image I want to keep the aspect ratio of and just have it overflow it's div as required to keep most of it displayed and the side bar I just want to fit to 100% of the page height. Here is my code at present:

<html>
<head>
<meta charset="UTF-8">
<title></title>
<style>
html
{
height: 100%;
margin: 0;
padding: 0;
}

body
{
height: 100%;
margin: 0;
padding: 0;
}

#page 
{
width: 100%;
height: 100%;
margin: 0;
padding: 0;
}

#sidebar
{
float: left;
width: 20%;
height: 100%;
padding-bottom: 10;
margin: 0;
background: url(/Images/bg.jpg);
}

#slideshow
{
float: right;
width: 80%;
height: 100%;
overflow: hidden;
margin: 0;
padding: 0;
}

#logoimg
{
width: 80%;
margin-top: 10%;
margin-left: 10%;
margin-right: 10%;
}

#mainimg
{
width: 100%;
overflow: hidden;
}

.link
{
font-family: courier;
font-size: 1.3em;
text-align: center;
padding-top: 7%;
padding-bottom: 1%;
color: rgba(255,255,255,1.00); 
}

@font-face
{
font-family: courier;
src: url(/courier_new-webfont.ttf);
src: url(/courier_new-webfont.eot);
src: url(/courier_new-webfont.woff);
}

</style>
</head>

<body>
<div id="page"><!--Whole page container-->
<div id="sidebar"><!--Side bar container-->
    <div class="link" id="logo"><img id="logoimg" src="/Images/logo.png"></div>
    <div class="link" id="homelink">Home<!--Home link--></div>
    <div class="link" id="aboutlink">About<!--About link--></div>
    <div class="link" id="gallerylink">Gallery<!--Gallery link--></div>
    <div class="link" id="priceslink">Prices<!--Prices link--></div>
    <div class="link" id="reviewslink">Reviews<!--Reviews link--></div>
    <div class="link" id="contactlink">Contact<!--Contact link--></div>
    <div class="link" id="clientslink">Clients<!--Clients link--></div>
</div>
<div id="slideshow"><img id="mainimg" src="/Images/main.jpg"><!--Image slideshow container-->
</div>
</div>
</body>
</html>

Any help with this would be really appreciated and don't hesitate to point out any massively amateur mistakes. I'm willing to take any criticism and learn from it. Thanks

Here’s just a simplified code example of the HTML:

<div id="welcome">
    your content on screen 1
</div>
<div id="projects">
    your content on screen 2
</div>

and here’s the CSS using vh:

div#welcome {
    height: 100vh;
    background: black;
}

div#projects {
    height: 100vh;
    background: yellow;
}

From Here: http://stanhub.com/how-to-make-div-element-100-height-of-browser-window-using-css-only/

It works for me.
