angular material mat-drawer issue with height

For some reason, I can't seem to get the mat drawer to occupy the remaining available height on the screen. I've tried:
.drawer-container {
position: fixed;
height: 100%;
min-height: 100%;
width: 100%;
min-width: 100%;
}
But I still get an overflow for some reason even though there's only one element on screen as indicated by the scroll bar:
And when I remove the CSS rules, I end up with this:
Basically about 10% of the screen height only. I've considered using a fixed height, but I'm guessing it would look cut off if viewed on a larger or smaller monitor. I'd appreciate any help as I'm really not familiar with the full properties of angular material and how to properly manipulate them. Thanks in advance.

in case any dropped by this and had a similar problem.
i fixed this long ago by applying
.drawer-container {
position: absolute;
top:0;
width: 100%;
bottom: 0;
}
just make sure the parent has a position: relative

Percentage based width/height is not yet supported by mat-sidenav i suppose.
try height: 100vh; instead.
that should work, but will add a scrollbar if there is any toolbar in your page.
UPDATE:
HTML:
<mat-drawer-container class="parent" autosize>
<mat-drawer mode="side">
Your sidenav content
</mat-drawer>
<div class="content">
Your main content.
</div>
</mat-drawer-container>
CSS:
.parent {
width: 100%;
height: 100vh; // calc(100vh - 64px) can be used if there is navbar at the top
}
.content {
height: 100%;
}

Overlaying divs on responsive parent div with background image

What I'm trying to achieve is a div container that is responsive but the ability to overlay highlight fields that will stay in the same place based on the parent div. I want to be able to highlight certain areas of text or form fields but have the form be responsive. Here's a link to an example: http://www.codeply.com/go/nufYSSEMir
As you can see the highlight div is position: absolute; so obviously it's going to stay exactly where it's at. I've tried using percents as top and left values but it doesn't scale with the background image. I have a feeling that my two options are to either have the width as a static value and set the meta viewport to scale to the window size, or get crazy with some JS and maybe jQuery.
Thanks in advance for any and all suggestions.

As said by divix, you need to set position : relative to the parent div.
This will tell the browser that your highlight's position : absolute is absolute in reference to outerContainer.
Basically any position:absolute will look at the first parent that has a position set (whether it's relative, fixed, absolute etc) to calculate top|right|bottom|left offset. If you don't have any parent that has a position set, it will just take the body as a reference
Edit: In order the get the right responsivness try this :
body {
background-color:#ddd;
}
#outerContainer {
background: transparent url("http://scontent-ord1-1.xx.fbcdn.net/hphotos-xpl1/t31.0-8/s960x960/12605534_504076036438839_6108375615162000201_o.jpg") no-repeat scroll center top / 100% auto;
height: 960px;
margin: 0 auto;
max-width: 742px;
width: 100%;
position: relative;
}
#media only screen AND (max-width:742px){
#outerContainer {
height:0;
padding-top:129.5%;
}
}
#innerContainer {
background-color: rgba(0, 255, 0, 0.5);
border: 1px solid #000;
height: 8%;
left: 12%;
position: absolute;
top: 14%;
width: 30%;
}

Simply add position: relative; to the #outerContainer, it works for me.

Displaying Iframe on top of image?

Problem
I want to display an iframe within an image, but have no idea how to do this. Is there a better way than purely positioning with css?
I have a html page that displays other websites, and I would like to display an iframe within the screen of the image below on that page.

I made the screen a background image and then used a absolute positioned iframe.
i added a YouTube iframe to the screen in the demo.
Demo
.outer {
background-image: url('http://i.stack.imgur.com/6hnLq.png');
width:420px;
height:365px;
}
.inner {
position: relative;
background-color:;
left: 67px;
top: 109px;
width:277px;
height:150px;
}
............
<div class="outer"><iframe class="inner"></iframe>
you could even use a 2 or 3px border-radius to match the image.

Basically you want to place the iframe in a container that is positioned absolutely. Then place it directly over the image. Here is an example. Please note the iframe link will not work inside of the fiddle due to JS Same origin issues.
http://jsfiddle.net/weyg1opk/
<div class="image_container">
<img src="http://i.stack.imgur.com/6hnLq.png" class="preview_image">
<div class="container">
<iframe class="iframe_example" name="iframe_example">You do not have iframes enabled</iframe>
</div>
.container {
position: relative;
top: 110px;
left: 68px
}
.image_container {
width: 421px;
height: 365px;
}
.preview_image{
position: absolute;
}
.iframe_example {
width: 270px;
height: 155px;
z-index: 1000;
}

maybe you can:
Crop the image into pieces and replace the screen image with a iframe without border and fixed size
or
Use the monitor as background, and use a div with absolute position to exact match the screen size and position.

Scrolling div without fixed height

I need to build a dynamically-resizing scrolling div.
The div should dynamically resize to fit the screen. But if the content doesn't fit on the screen, it should display a scrollbar. So the browser's own scrollbar should never need to become active.
I can get a scrollbar to appear in the div by placing another div inside it and using overflow: auto.
<div id="gridcontainer" style="overflow:auto;height:300px; width:100px;" >
<div id="gridcontent" style="height:100%">
<!--Put loads of text in here-->
</div>
</div>
The trouble is that this only works when the first div has a fixed height. I had hoped I could just set the first div to height:100%, but sadly not- this property appears to get ignored, and the scrollbar just doesn't appear.
I have tried putting the divs in a table with height:100%, and setting the first div to height:auto, hoping it might take its height from its parent. But the div still seems to ignore the height property.
So my question is: Can this be done using just html, or- failing that- javascript?

You could stretch the div using absolute positioning. This way it will always take the size of the browser window (or the closest positioned ancestor).
Given this HTML:
<div id="gridcontainer"></div>
the CSS should be something like:
#gridcontainer {
position: absolute;
top: 0; bottom: 0; left: 0; right: 0;
overflow: auto;
}
Live Demo

Since IE9 you can use viewport units.
Let's say that the height of your container is dynamic, unless its size is greater than the window height. In that case we stop the expansion & activate the scroll.
#container{
background: #eaeaea;
max-height: 100vh;
overflow-y: scroll;
}
div{
outline: 1px solid orange;
width: 200px;
height: 200px;
}
<div id='container'>
<div></div>
<div></div>
<div></div>
<div></div>
<div></div>
<div></div>
<div></div>
</div>

If you are trying to make element fit the screen then you can set the value of hight and width of the element to 100%.
You will also need to set the height of html and body
html, body {height: 100%}
#gridcontaine {
height: 100%;
width: 100%;
}

Best way to size an element to the size of another element

I am using an old CSS trick to get a semi-transparent background for some content, without the content appearing semi-transparent. Here is the HMTL:
<div id="frame">
<div id="opacityFrame">
</div>
<div id="contentFrame">
<div>
<!-- Main Site Content Here -->
</div>
</div>
</div>
Here is the corresponding CSS:
#frame
{
width: 90%;
margin: auto;
position: relative;
z-index: 0;
}
#opacityFrame
{
background: #00ff00;
opacity: .15;
top: 0;
left: 0;
position: absolute;
width: 100%;
height: 100%;
z-index: 1;
}
#contentFrame
{
top: 0;
left: 0;
position: absolute;
height: 100%;
width: 100%;
z-index: 1;
}
My problem is that because #frame is position: relative, it's height does not dynamically expand with its content. Both #opacityFrame and #contentFrame are set to 100% height and width and they appropriately expand to fill #frame which is great. The issue is that I need #frame's height to grow with the contents of the child DIV of #contentFrame because that DIV's height dynamically adjusts with the content placed in it.
I ended up having to create a jQuery function:
function resizeFrame()
{
$('#frame').height($('#contentFrame > div').height());
}
NOTE: The reason there is a child DIV of #contentFrame is because #contentFrame's height always reads as zero for some weird reason. I'm assuming it has to do with its position being absolute.
This code works great and accurately resizes #frame's height to the height of the child DIV of #contentFrame. However, I do a lot of ajax that changes the content within that DIV. One solution would be to call resizeFrame() with EVERY ajax event but it just seems so tedious. Is there an event or something I can tie to that would execute this function without my explicitly having to call it? I tried the following events but they didn't seem to work; maybe I did them wrong.
$('#subFrame > div').resize()
$('#subFrame > div').change()
Neither of these seemed to fire when the contents of the child DIV were modified. Maybe I'm going about this the wrong way? I do not want to use transparent images for the background.

Try taking position: absolute off of the contentFrame but leaving it on the opacityFrame. That should cause it's parent to resize, and the opacityFrame to still overlay everything.

do you have to use opacity? If it's a solid color, consider RGBA or if it's not solid, consider a semi-transparent PNG. That way you can nest them.
