Ok, so I've got an issue.
Working on a simple site, which has a regular background, and an opaque main container, that also includes nested elements inside of it. Because of the nature of the site, the main container must be able to grow vertically, should the content within the body become larger. Basically, the main container must dynamically grow to fit all the floated content within.
My problem is this.
I can do this one way, where I nest elements in a main container div, and then change the opacity of that main container div to match what I need. This is easy. the problem here is that the opacity of the other elements nested within is inherited from the parent main container. I can fix that, but I do not know if it would be semantically correct for the site, or if the workarounds for alpha filters will be the best workaround.
Another option I have is creating a background img that is set at 90% opacity, and then tiled vertically. The issue here is that I HAVE to specify a height, which does not allow the main container to stretch dynamically in a vertical direction. This takes care of the semantics problem, and the opacity problem, without too much cross browser manipulation, but I don t know how to make the main container div resize itself dynamically. I'm sure there is a solution to do this with javascript or some other programming language, but that's not really my forte.
So I guess what I really want to know is this, Should I go with the first option, and use the browser manipulation for opacity, or is there a better way to be able to dynamically resize the main container div so that the image is tiled to the specific height which the content takes up?

I'm having some trouble with the current layout of my polymer site, specifically with regards to nested components and their associated scrollbars. I'll preface this by stating that by absolutely no means am I a CSS guru. I wish I was because I probably wouldn't be struggling with this as much as I am. Also feel free to jump straight to the jsbin URL as my issue may become apparent.
The situation:
I currently have a nested core-scaffold element, whose main content often requires vertical scrolling and thus it's vertical scrollbar becomes active as required. However, as it is nested, it's container(s) can also have scrollbars enabled. Ideally, I'd like a single scrollbar on the highest level element which can scroll the scaffold's content to it's full vertical extents, yet also cause the topbar to slide away as it does now when scrolling down. I've also noticed that the height of the scaffold's main content is determined by the first page that is loaded into it. Subsequent page loads with different heights does not cause the scrollbar height extents to change accordingly.
Please note that I've simply inserted an iframe loading external content into the scaffold's content section for the purpose of this jsbin demo. My actual site loads a bunch of data driven collapsible height containers within the content pages, wrapping horizontally as needed. Due to their collapsibility, their containing page therefore has a dynamic height. That height can vary from page to page as container heights within them vary.
Here is the jsbin. Whoever can remove me from this css hell will be considered my hero...

In my initial jsbin sample code, you'll notice I have specified core-pages height as '100vh' the top level polymer element (i.e. my-app-element). The second level polymer element (i.e. my-scaffold-page-element), loads within the aforementioned core-pages. Therefore, the nested scaffold element's maximum height is 100vh. Further down the chain, when the scaffold-element's main content area's height flows past its host's height limitation, it caused a secondary 'inner' scrollbar to appear, which has a different vertical extent than the original outer scrollbar...so trying to use the outer scrollbar alone doesn't effectively scroll the inner content to its entire vertical extent, forcing you to use the inner scrollbar as well to get the job done. Ugly to say the least.
Now that I know that is the case, one way to reduce the likelihood of an inner scrollbar appearing for the nested scaffold element's main content area is to change it's parent element's core-pages height to something much greater than 100vh (400vh?). Doing so solves the problem in a roundabout way. The outer scrollbar can now be used to scroll the entire vertical extent of the nested scaffold's contents without an inner scrollbar occurring.
In the new jsbin example (below), you can witness the 'fix', which also happens to remove the reliance on core-scaffold, instead preferring to utilize its individual components in a more configurable fashion.

I have a main container div, where all the important content of the site is inserted, 800px wide, centered horizontally.
I need to put multiple absolute positioned divs layered below it (via z-index) and outside its width, without causing extra scrollbars to appear, and without losing the main container scrollbars (so puting overflow:hidden in a wraper won't do).
In other words, I was wondering if it's possible to create divs with different elements inside (videos, images, or text) that could be treated as backgrounds, so that the scrollbars would only appear when the window resizes below the 800px wide (width of the main container), and the rest of the divs would just bleed out (something similar to what swffit causes with an embebed flash movie).
Is there any way to do this via css or javascript?
Thanks in advance!
There is a way that requires CSS only. I once faced similar problem with this web site I created, take a look at the source. The curves by the side are done this way.
Trick is to change positioning of main container to relative with no shift - that causes change of coordinates base, here is a link. Than use absolute positioning of the "background divs" to get them outside the main box.
To solve the overflow problem use some extra div wrapper (in my site with id graphic). To specify its width use a range - min-width equal to main box and max-width as total width including the "backgound divs". And to this wrapper set the hidden overflow.
Hope it helps.
Basically I have a parent div with height and width and overflow:hidden and then within that some more divs with it.
We are dealing with fluid content and some of the divs go over the corners so get hidden.
But one is half and half.
Is there a way to make that completely hidden?
CSS would be best.
I don't think you can know if a child from an overflow:hidden parent is in the hidden or visible section without using Javascript (I might be wrong here).
What I suggest is that you set all the child divs to a fixed dimension d and set the parent div to a multiple of d so every child is either completely visible of not.
This solution won't work if you fill your divs with different-length content
If I understand your post, you have a wrapping div that has overflow:hidden and you want to make any child element hidden unless it can be completely displayed within the wrapping div.
There may be a better way to do it, but I would use a CSS media query. If you're unsure of how they work this is a good place to start:
http://css-tricks.com/resolution-specific-stylesheets/
Using this method, you could determine how many blocks of each type should be displayed on any given set of resolutions. I'd be interested in seeing how it goes, or if you end up using a different approach. Best of luck!
I'm having one of those pull-my-hair-out moments that has become an all consuming obsession at work and I can't figure it out for the life of me.
I'm working on a site where I have a repeating background image (gradient of blue) and I need to put another image on top of that which goes beneath my "container" div. The large image that I'm having to put the "container" on top of has designs that appear to pop out of the sides.
The trouble that I'm having is this: when the user shrinks the window size, my buttons (that are within the container div) get all jumbled up and go one on top of another when I do this in IE and Firefox. I would like it to stay in the same spot on top of the large image in its spot despite the size of the window.
I think it has to do with absolute position, something that I'm not too familiar with, but I'm wondering if this is possible. I have also never used tables and have just used div tags to create sites. Fairly new at this - just have been designing websites for about a year now.
Help!
I am answering this without seeing an example, so bear with me.
It sounds as though the container div does not have a width assigned to it.
Since the container div doesn't have a width, it is shrinking and expanding causing the buttons to jumble up. Also, make sure that your buttons and such are positioned absolutely inside of your container div. Your container div must have position:relative; set in its style in order to absolutely position items inside of it. However, it sounds as though you have your positioning already set accordingly, it is just worth re-mentioning.
I am working on a web page that used a fixed width layout, centered in the browser. The width of the centered container is set in pixels.
On a couple of pages, there is a large data table inside the content container. In Firefox the table overflows the fixed width container. IE is more complex and will expand the container around the table, and because of some layout issues the container uses overflow:scroll just for IE.
I need to find out if I can use a fixed width on the container, but also allow it to expand to wrap the large data table. I also need to avoid a solution where I would be modifying the HTML... I can't for example use an ID to only target those containers on pages with large tables. I need a pure CSS solution.
My feeling is that this is impossible, and I am going to HAVE to put an ID on those specific containers that need to be larger than the standard. I'm asking here because I really need a second opinion.
Just a note: I have also experimented with min/max-width, without success.
If min-width and overflow don't work, you're going to need css hacks.
If the problem with min-width is that the container is a block-level element and expands to page width, try using a variant of display:inline on that container, so it doesn't stretch. (Or maybe margin.)
