I'm trying to create a table of rows, each of which has some content in some block element (I'm using a DIV in this example for simplicity) whose element I want to stretch to the full height of the TD cell. In this example, the "test" text on the right should have its containing grey DIV filling up the full height of the containing TD cell:
http://www.game-point.net/misc/browserTests/scratchpads/fullTableCellHeight/
I don't want to explicitly set the height of anything (except maybe to a percentage) - setting height:100% on the child DIV doesn't change its height. Is there any way to do this? It seems absurd that the browser, which obviously knows the table cell's rendered height, provides absolutely no way to size a child element to fill it without using Javscript!
NOTE: I'm aware that there are other questions similar to this but they don't seem to take into account CSS3's new flexbox functionality - perhaps that could solve this problem?
You can set the parent element to relative positioning and the child to display block and it should fill the height. I use the technique a lot when trying to get link text to fill the entire button container. Hopefully, it translates to what you are trying to do but since you have no code to show I will give you a brief example of a real life scenario when I use it:
<div style="position:relative; width: 50px; height: 50px;">
some link
</div>
I'm told by Boris Zbarsky himself that it is completely impossible to do this - make a child element of a table cell fill the cell's full height - unless the height of the cell is specified explicitly. Browser makers could probably make this work if they wanted to, but they can't be bothered.

I am using a table based layout (using display: table properties). The container has a dynamic height (I have set min and max height properties on the container). All the inner elements within the container have their heights set to 100%. The idea being that they will always fill the available space.
The problem I am having is that elements that have display: table-cell will continue to expand above the 100% allocated space if they contain content that is taller than them. This happens even if I set overflow: auto.
I have created a jsfiddle to demonstrate the issue. Please see here:
http://jsfiddle.net/eSRA8/
In this example, the max-height of the container is 300px, but an inner element called .tall-content has a height of 400px. This makes the container grow taller than its max-height.
In Chrome this actually works how I want it to. However it does not work in Firefox or IE.
Please note that since the container height is dynamic, I can't set a fixed height on any of the inner elements (unless it is possible to use jQuery to assign the correct height on document load and on window resize, but this would need to respect the min and max height settings of the container).
Does anyone have any idea how I can achieve the desired result? I would like to keep as much of the existing structure as I can but if the same result can be achieved in a slightly different way then I'm open to that. Either way it needs to work the same in all browsers.
That looks to be a limitation of display:table;
You may be able to put the "container" in another div with max-height:300px;overflow:auto;
Here's some info which might explain why you are having difficulty:
http://www.w3.org/TR/CSS21/tables.html#height-layout
Without fixing the widths of any of the elements, I would like the parent div element to ignore the text when setting it's width. I want the element's width only to be affected by the width of the image.
<div>
<img src="https://lh4.ggpht.com/9BAW9uE48gxNUmnQ7T6ALpNTsrCHOZBMfF__mbamBC36edSw0uc-kjQxgtZ3O3aQWFY=h900"/>
<p>I want this text to wrap once this paragraph element reaches the width of the image.</p>
</div>
div {
background: green;
display: inline-block;
}

Any advice is greatly appreciated
Change display property of div to table-caption
(Tested in firefox and chrome)
Updated jsfiddle
Here's the best that I've found:
http://jsfiddle.net/y8Qnd/3/
What I've done is to take the p tag out of flow with position: absolute so that the containing div has the width of just the image. Then, have the p tag inherit the width of its parent, the container. This does not fix the width of the p tag, and is completely cross browser.
This would mean you would have to move up the DOM tree, as you want the image to determine it's parent width. Moving up the DOM tree is unfortunately not possible (yet).
As an alternative, you could position the text absolute, to lift it out of the document flow, and therefore not influence the width of it's parent div. This however would also mean that the height does not get influenced, which is probably not what you are after. You could mimic the correct height by repeating the parent background, but the content underneath would not get pushed down, so that is also not really an option I think. I set up an example anyway: http://jsfiddle.net/y8Qnd/2/
The only option I can think of is javascript. Get the width of the image and apply it to the parent container. In jQuery (I will probably get bashed for using jQuery for such a trivial thing, but I am just not used to writing 'old school javascript' anymore...) it would look something like this:
var $wrapper = $('div'); // you will probabaly want to use some id or class here
var width = $wrapper.find('img').width();
$wrapper.css('width', width);
and an example: http://jsfiddle.net/y8Qnd/6/
I'm trying to make a box with rounded corners where the height and width of the div depends on the content, so it's automatically adjust to it...
You can see the example here: http://pastehtml.com/view/1duizyf.html
The problem is that i can't get the "test_mid_left" (black background) and "test_mid_right" (turquoise background) to inherit the height from the "test_mid_center" (green background). I have tried height: 100% and auto, but none of thoose work. So how do I get them to inherit the height from the content?
(The reason why I have used "min-height: xx" in the left and right content on the example is just to show which boxes I am talking about)
As already mentioned this can't be done with floats, they can't inherit heights, they're unaware of their siblings so for example the side two floats don't know the height of the centre content, so they can't inherit from anything.
Usually inherited height has to come from either an element which has an explicit height or if height: 100%; has been passed down through the display tree to it.. The only thing I'm aware of that passes on height which hasn't come from top of the "tree" is an absolutely positioned element - so you could for example absolutely position all the top right bottom left sides and corners (you know the height and width of the corners anyway) And as you seem to know the widths (of left/right borders) and heights of top/bottom) borders, and the widths of the top/bottom centers, are easy at 100% - the only thing that needs calculating is the height of the right/left sides if the content grows -
This you can do, even without using all four positioning co-ordinates which IE6 /7 doesn't support
I've put up an example based on what you gave, it does rely on a fixed width (your frame), but I think it could work with a flexible width too? the uses of this could be cool for those fancy image borders we can't get support for until multiple background images or image borders become fully available.. who knows, I was playing, so just sticking it out there!
proof of concept example is here
The Problem
When an element is floated, its parent no longer contains it because the float is removed from the flow. The floated element is out of the natural flow, so all block elements will render as if the floated element is not even there, so a parent container will not fully expand to hold the floated child element.
Take a look at the following article to get a better idea of how the CSS Float property works:
The Mystery Of The CSS Float Property
A Potential Solution
Now, I think the following article resembles what you're trying to do. Take a look at it and see if you can solve your problem.
Equal Height Columns with Cross-Browser CSS
I hope this helps.
The negative margin trick:
http://pastehtml.com/view/1dujbt3.html
Not elegant, I suppose, but it works in some cases.
You need to take out a float: left; property... because when you use float the parent div do not grub the height of it's children... If you want the parent dive to get the children height you need to give to the parent div a css property overflow:hidden;
But to solve your problem you can use display: table-cell; instead of float... it will automatically scale the div height to its parent height...
Most of the times, the Previous parent has a heigt manually set, so you can use that value as reference, no other dirty tricks will be needed, and if the number is not the same for any reason maybe a comment can be added with the original number so in case you need to change it, by searching at the all the values, this one can be adjusted or even changed, in the time someone resolve this one for us.
Do elements before they are part of the dom have the width and height set properly? ie if I create a div containing markup can I measure its intended width and height without appending it to the dom?
I don't formally know the answer, but a little gedankenexperiment lets us see that it can't, in general, happen. If you create an HTML element with a fixed width and height, then yes - you can know the width and height.
However, if you don't specify them (or they might not be obeyed), then the width and height are always going to be calculated by the contextual position of the fragment in the DOM; for example, a DIV with width: 50% cannot know it's actual width until it is added to the DOM and laid out - there's no other way to answer "50% of what?".
Take a look at http://www.barelyfitz.com/screencast/html-training/css/positioning/ item 6. It says:
It is not a viable solution for most designs, because we usually do not know how much text will be in the elements, or the exact font sizes that will be used.
What workaround do I need to use in order to insert dynamic text into a div with absolute position?
Any approach is welcome
regards,
If your primary goal is to keep the div in it's place, without changing it's height or width based on the amount of text, I'd go with:
div {
overflow: scroll;
}
The other option is to have the text size shrink to fit into the div, but that involves a certain amount of fuzzy math and you run the risk of the text being so tiny it's pointless.
If you want the div to change it's height based on the text, this also involves some fuzzy math, but basically, you would get the length of the text with:
var sometext = "Hey, I'm some text!";
var textlength = sometext.length();
And make the height change in relation to that length. You'd want to play with the numbers, but it would look something like:
var div_height = 10 * textlength;
$("div").css("height,"+ div_height +"em");
See Visual Effect section from W3C site here
Maybe using "overflow: auto" for the dynamic-text-container div.So the height isn't a problem.
The problem isn't putting the dynamic text in the absolutely positioned div - the div will expand to fit whatever text is in there. There are no heights defined on the red and green divs in your example.
Absolutely positioned divs are taken out of the flow of the document so anything that appears after them in the html will act like they aren't even there.
Designs that use absolutely positioned divs need to have a height defined on the containing div so the absolutely positioned divs don't overlap other content. In your example <div id="div-1"> has a height of 250px defined. Change that to 100px and you will see <div id="div-after"> move under the red and green divs.
So if you have a absolutely positioned div in a sidebar with nothing after it you can add all the dynamic text you want. If you have one in your header, it is going to make your design very complicated to implement.
