CSS How to set div height 100% minus nPx

I have a wrapper div which contans 2 divs next to each other. Above this container I have a div that contains my header. The wrapper div must be 100% minus the height of the header. The header is about 60 px. This is fixed. So my question is: how do I set the height my wrapper div to be 100% minus the 60 px?

<div id="header"></div>
<div id="wrapper">
  <div id="left"></div>
  <div id="right"></div>
</div>

CSS: 100% width or height while keeping aspect ratio?

Currently, with STYLE, I can use width: 100% and auto on the height (or vice versa), but I still can't constrain the image into a specific position, either being too wide or too tall, respectively.

Any ideas?

CSS / JavaScript - How do you get the rendered height of an element?

How do you get the rendered height of an element?

Lets say you have a <div> element with some content inside. This content inside is going to stretch the height of the <div>. How do you get the "rendered" height when you haven't explicitly set the height. Obviously, I tried:

var h = document.getElementById('someDiv').style.height;

Is there a trick for doing this? I am using jQuery if that helps.

Percentage Height HTML 5/CSS

I am trying to set a <div> to a certain percentage height in CSS, but it just remains the same size as the content inside it. When I remove the HTML 5 <!DOCTYTPE html> however, it works, the <div> taking up the whole page as desired. I want the page to validate, so what should I do?

I have this CSS on the <div>, which has an ID of page:

#page {
    padding: 10px;
    background-color: white;
    height: 90% !important;
}

Make div 100% height of browser window

I have a layout with two columns - a left div and a right div.

The right div has a grey background-color, and I need it to expand vertically depending on the height of the user's browser window. Right now the background-color ends at the last piece of content in that div.

I've tried height:100%, min-height:100%; etc.

CSS: Setting width/height as Percentage minus pixels

I've seen this question asked in a couple other contexts on SO, but I thought it would be worth asking again for my particular case. I'm trying to create some re-usable CSS classes for more consistency and less clutter on my site, and I'm stuck on trying to standardize one thing I use frequently.

I have a container div that I don't want to set the height for (because it will vary depending on where on the site it is), and inside it is a header div, and then an unordered list of items, all with CSS applied to them. It looks a lot like this:

Widget

I want the unordered list to take up the remaining room in the container div, knowing that the header div is 18px tall. I just don't know how to specify the list's height as "the result of 100% minus 18px". Does anyone have any advice in this situation?

Set iframe content height to auto resize dynamically

I was myself searching for a simple solution to change the height of an iframe with the content in it.

It seems like the rules are that you can't get the height of the iframe from the page holding it. This is because of security apparently. How can we do this?

How to Force Child Div to 100% of Parent's Div Without Specifying Parent's Height?

I would assume this is possible, but i just cant figure it out..

i have a site thats basic structure is set up as follows.

<div id="header"></div>

<div id="main">
  <div id="navigation"></div>
  <div id="content"></div>
</div>

<div id="footer"></div>

The navigation is a left hand navigation with a content div to the right of it. I would like to scale the navigation vertically to be the same height as the content div depending on what is loaded into the content div. the information for the content div is pulled in through PHP, so it is different every time. anyway long story short. Is there a way to set it so that my navigation will always be the full height of the content div no matter which page is loaded?
