I am currently working on a prototype that is using CSS3 multi columns for dividing up content and it appears to work well. My issue is that inside of a block that is part of the columns there is an expanding height section and well, in Firefox when the height of an element inside of a CSS3 multi-column changes it disappears and then Firefox crashes.
Shouldn't CSS3 multi-columns take into account varied height content inside or is it not made for that sort of thing? I'd really hate to have to use a plugin like Columnizer, because Columnizer is a pain in the butt to get working correctly.
Here is the layout:
[DIV]
[CONTENT] - Default height is 38 pixels
[EXPAND LINK] - A link when clicked that modifies the height of content to be 52 pixels.
[/DIV]
The issue is as soon as the link is clicked and the height changes, it's like it loses its layout and positioning (the height and width change to 0), then Firefox crashes. This is also the case if I use Firebug to change the height manually.
I resolved the issue right are posting this question basically and my solution was as follows in-case someone else runs into this issue which I believe some will.
I had a parent div element with the appropriate CSS3 multi-column code. The inner elements are article elements (you could just use div's though). The issue was that the inner article elements were being floated left (just out of pure habit of having to float things to give the appearance of columnised items). The floated elements were clashing with the CSS3 multi-column code thus crashing the browser.
I'm guessing that because a float modifies the layout of an element, the multi-column code was trying to perhaps readjust the box and then getting into an endless loop. I'm not entirely sure what went on, but floating elements inside of a multi-column div or anything is bad.

First off, i'm not really a good coder. I'm an IT but more of an infra guy but i do understand concepts about coding and maybe a bit of a good grasp about it. I am working with my website and it's under construction using wordpress. In my homepage, i plan to do it simple as it is and decided to use the page builder and use text or HTML (or any language) to maximize it. I hope some one can help me. I would really appreciate it.
Here it is:

Those images have onmouseover style and was able to do it.. the thing is i can't arrange it horizontally. :( and unable include arrow so they can move left or right to see each images :(.
I know i can also do the same on the icon part the moment someone help me about the concept i wanted.
Your question is pretty ambiguous as to the specific context of the solution.
However, in general the reason why things don't align horizontally when rendered on screen in a browser, is that most elements (including the popular <div>) have a default styling of display: block; which makes it take up the full width of its parent item if the parent itself has the same styling (cascading of this is a different discussion).
The general solution to this is to define the widths of the elements. And they will be placed on the same line to the extent that the widths of the elements allow for more than one to appear on the same line.
One way to solve this is to have elements widths defined in some way. This could be by applying a class with a width: 25%; for example. This would allow for 4 elements with the same width to fit on the line.
Alternately you can also set the display property value of the elements you want on the same line to inline-block. This will make those elements take the width of it's content (unless the content has no width specified). This will cause the elements to flow along the horizontal line like text would (it will re-flow on the resizing of it's parent element), until there are no more contiguous items containing the inline-block display property.
Since your description also showed carousel style navigation for these rows of items, it may be that these are not the full solutions you are looking for.
If you are using the Bootstrap framework, there is a built-in carousel feature which you could use to contain these horizontally aligned elements on separate "pages" of the carousel. Making this solution fully responsive is another challenge altogether.
I am building a very simple page, powered by tumblr.
It has 3 columns of content in the main area. The content divs are all set to a width of 33% and floated left, most of the time this arranges itself as you would expect, but as you resize the window it seems to sometimes revert to 2 columns. Anyone know how to solve this?
The html is here: http://emilestest.tumblr.com
Try to set the .item css width to: 32%. The browser probably miscalculates width sometimes so you probably have a extra pixel or two, so the float overlaps to next line.
There is a Javascript action involved. Your article html elements gets the absolute position and some coordinates. Have a look over those scripts (or disable them, in order to use only CSS for positioning).
In your specific case, there are several solutions:
Place + size the divs with JavaScript and disable CSS layout
Use display: table
Use a table element
Disclaimer: For all those who cry out when they read table:
Using divisions to simulate a table for the display of tabular data is as much a design flaw as using tables to control graphic and page layout.

I'm having a slight problem. Whenever I hover over the "SEO" option on my navigation in IE, the navigation breaks & moves to the side. This doesn't happen in Firefox. Changing the navigation to position:absolute fixes it, but then the main content becomes merged with the navigation. It all validates. Any help would be much appreciated!

Thanks loads!
The navleft and navright divs are resizing independently, which is to be expected given your design structure. But it looks weird as it comes down on top of the content below:
One suggestion I can give you is not to set the navigation bar width in %, which you have done for these two divs. If you set a fixed width (in px) or remove the width specification completely (in which case it will take the width of its inner content), a horizontal scrollbar will appear below the page when the width is small, which I suppose is fine. Also, use as few floats as possible as they break the flow of content in the document and are more prone to breaking layouts. Both these divs have a float:left, which can be dumped for more stable solutions. I'm saying all this because I think the breaking of the layout on hover is occurring due to these reasons. If you can take care of this, your problem might disappear.
So my suggestion is to have a single nav div with width: 100%. Inside this put two divs: navleft and navright with display:inline and widths a.) specified in px or not at all, or b.) specified in % but with some min-width in px. If you don't specify any width for navright, it will expand to fill all of the space on the right.
This way these two divs will not reflow independently.
Basically, toy around more until you get better command over CSS; I think more experience will automatically help you sort out issues like this.
I use example 3 given in this page:
http://simple-navigation-demo.andischacke.com/
and I have a problem because when I open the main page (for example)
http://simple-navigation-demo.andischacke.com/
I get an empty div on the left instead of the content div filling the whole area.
On the other hand when I open a page from the menu (for example)
http://simple-navigation-demo.andischacke.com/books
Everything is just fine.
Can someone propose a solution? How can I completely remove the div in CSS if it does not contain anything?
There are lots of solutions; it depends on where you want your logic to be. A pure CSS solution might be tricky; it might be easier to do this sort of thing in JS.
That said, try changing #sub_navigation's width property to be a max-width instead. This way, it can still be set to float:left, but when there's no ul element inside it, it can collapse.
You might need to modify the width of your content div after that, but hopefully this gets you on the right track.
Alright, so this is basically the usual "how to vertically center with CSS" question, but with some catches.
No Javascript. HTML and CSS only. CSS3 is fine as long as it's reasonably well supported by today's browsers.
The element's content, and therefore height, is not known. It may be anywhere from a few dozen to a few hundred pixels. In the future I might even have a script adding and removing elements inside, so it may change height as the user is interacting with it.
There is other content on the page - a navigation bar at the left and a menu at the top. These need to be accessible.
The approach I've used is the three-container-div method using display: table-cell, as documented at: http://www.jakpsatweb.cz/css/css-vertical-center-solution.html this solves issues 1 and 2, but not 3.
http://imgh.us/vcenter.jpg shows the design and the problem. The yellow box is the innermost container. The red and green dotted boxes around the entire page (which have become somewhat blurred together due to JPEG encoding) are the outermost and middle containers respectively. (The out-of-place footer is a separate issue...)
The problem with this layout is the outer containers cover the entire page, and this makes it impossible to click on the navbar, because it's now "under" those containers. Z-index can move them to the bottom, but then it becomes impossible to click on anything inside the red box, because it's now "under" the page's main content box. (XHTML only allows a single element inside the <body>, so I've just wrapped it all in a <div>.) Even if the outer two containers have z-index: -100 and the inner container has z-index: 200, it still ends up under the main content box for some reason. (I did try various position attributes.)
The only solution I've seen is a new CSS3 property, pointer-events, that would in theory allow me to make events pass through the transparent containers as I'd expect; however this seems to be quite new and not yet supported by most browsers outside of SVG, and I imagine I'd have the same trouble as with Z-index.
I do want the element at the center of the page, not the center of the content area (i.e. ignoring navbars in the calculation of position), so placing the container inside the content area isn't an ideal solution. (I'm using this style on the login page as well, which has no navbars, and it'd look a bit strange if the "centered" elements were centered relative to a navbar that isn't always visible.)
In summary what I need is to center, without using Javascript, an element of unknown height on a page with other content at its edges, without covering any of the content with an invisible layer (and thus making it unclickable).
While this is obviously an old question and the OP has undoubtedly solved this problem, I figured I'd add a link to Chris Coyier's marvelous write-up on how to deal with this issue for future wayfarers in need of a similar solution.
