So I have a site with four main sections. The div for each section has a background image. All four backgrounds are the same size. There are also important elements in the images that I always want to show. In the original version of the page the image would resize depending upon the browser window size but much of the height of the background image was hidden in most cases. So I worked with a guy cleaning up the css and in the process we set the background images to always display 100% height. I was OK with some black background showing through on the sides a bit when necessary as long as I kept the height.
Anyway it worked well. The images expanded and shrank with the browser width, but they always showed the full height of the image. I signed off on the job and it looked good. Until I changed the browser window height (which is something I rarely think to do). Then the elements all spilled out to the right and left of the 4 main divs. I realize now that nothing in the document specifies the width of any section, just the height at 100vh. Only the fact that all four background images have the same dimensions makes it look like there are defined margins.
Is there a simple solution to this? I need to define a right and left border to the page to contain all of the inner divs and buttons, but I want to keep the 4 main divs showing 100% vertical height.
We are using
background-attachment: fixed;
background-size: cover;
background-repeat: no-repeat;
min-height: 100vh;
to define each of the four divs.
Basically I need a container surrounding the 4 main sections that expands to the width of the images, while still allowing the images to resize with the window, yet it keeps all of the other buttons and divs contained.
The page can be seen here: view-source:http://liquidpropane.io/hold/
It works right now exactly like I want except the buttons spill out the sides if the browser window is too short.
Thanks for the help Justin. In the end I did have to rethink the design. I wanted to keep the idea of using the background collages, but keep the responsive design. I moved the homepage logo out of the background image and into the banner section. Then I moved the important parts of the collage into the center part of the main image, and the less important parts to the sides. That way cropping at the sides will not matter. Finally I decided to remove the rounded text boxes out of sections 1 and 3. I will just use a small bit of landing page text (quite big in a thin font) on those pages and put the bulk of the content in sections 2 and 4. I have not added that text in yet, but the cleaned up version of the background and banner can be seen at http://liquidpropane.io/newhold
I guess the takeaway that is not specific to just my case is that if information in the background image is important and you want a responsive site, then the important part of the image needs to be centered because there is always the likelihood of cropping on the edges.
I have a project that involves having a sidebar that floats over an image. The sidebar is set to position: absolute to keep it over the image and to help it scale along with it when the screen size changes.
Here is a codepen that basically recreates what I'm working on: https://codepen.io/gojiHime/pen/JmYqaz
The issue I'm having is with controlling the size of the contents within the wrapper container. I want the preview div to scale along with the wrapper container. Currently, it does not work as expected in that the preview div does not start scaling as the width and height change for wrapper and for thumbs-inner. The thumbs-inner div scales correctly for the most part, but the bottom of div is cut off so you can't see the bottom of the scroll bar in smaller screens.
I know I set overflow: hidden on wrapper but without it the content in preview would extend outside of it as the height of wrapper changed.
So, I'm looking for ideas on how to fix the aforementioned issues. wrapper must stay absolutely positioned and the thumbs-inner div needs to have a vertical scrolling feature, so I can't do anything with those. I don't think setting a height makes sense for wrapper since it needs to scale responsively in height and width.
EDIT: Not sure how much this will help but this is a screenshot of what the layout of everything should look like: enter image description here
The Kraftmaid logo, full-size thumbnail and the text below it (which are in the .preview div in the codepen) have to be visible at all times when changing the screensize.
I'm not sure if this is exactly what you're looking for, but generally for responsive layouts you would want to avoid fixed dimensions, such as specific widths set in x number of pixels.
This shows your code with responsive layouts for .wrapper and .thumbs-inner (note that I haven't addressed any content issues within those two divs since I have no idea what your intended layout is):

Note that:
I've switched the two layout divs to use box-sizing: border-box; which will allow you to use pixels for margin and padding but still use percentages for width.
I've removed width from .wrapper and switched to percentage based absolute left and right declarations - if you modify these values, the layout should still work.
I've added borders to make the layout more obvious.
Why are the images for the cards component being used as a background instead of the image to fill up the media portion of the card? cant we just use the image tag instead?
I am trying to use the MDL framework to make a tumblr template
but having trouble implementing the card component for the images posts since tumblr uses image tags
please explain why MDL is using images as backgrounds for the card component
Nothing is really holding you back from using the img tag. See this as an example.
However using images as background of divs has some advantages:
Right clicking on the image does not allow you to download the image
You have more flexibility in terms of responsiveness (e.g. by using background-size: cover to fill the div). UPDATE: even though you can set 100% on width/height to adapt the image, cover keeps the aspect ratio and in general provides better results.
Since your image is just a background you don't need to set its position to absolute to let other elements inside the div be positioned over the image (as it is the case in all of MDL examples)
I hope what I try is not impossible.
Let me explain first: I have a responsive design which requires a background to be fixed under some situations (media query blocks). The design in question is this one:
http://think-open.at/fileadmin/templates/responsive/content.html
Basically there are two media queries: one for the maximal height and one for the minimal width. If there is enough viewport height there is a scrollbar in the content area and the design height is fixed. But if the viewport is not large enough for showing the predefined height the height-mediaquery removes the scrollbar from the inner div so there won't be two nested scrolling containers (body + div) and sets the content area to height: auto.
There is also a responsive media query if the viewport is too narrow but this works flawless.
Now the problem: When the design switches to the mode where the whole page scrolls (below 830px height) I would like to position the image in the right container "fixed" so it does not scroll out of the viewport. But then the problem arises, that I can't really position the background in regards to the container div as "fixed" positions an background image in regard to the viewport. I have created a CSS fiddle here:
http://dabblet.com/gist/ae5c3598e1465ce0c90e
If you change the width you notice the problem. I would like to have the right border of the image aligned with the right border of the green box.
Is this somehow possible? I have no problem using calc() as there will be a condition in my CMS to use the plain old-school design if an older browser gets detected.
I solved it myself now. Sorry for posting.
The trick was: As my design is centered, I started to try using calc(50% + somepixelvalue). This did the job.
I adjusted the CSS playground:
http://dabblet.com/gist/5b63553f47a81f3bb701
Now the image is always up in line with the right border of the green area. When scaling there is sometimes a 1pixel difference but this doesn't matter as the background will get assigned to some container element which acts as mask.
I have a really cool website that allows people to upload images. Sometimes there images are really large, as seen in the below div:
![Overflow][1]
Is there a style that can I add to my DIVs to fix this?

Set your CSS overflow property on the div to one of these:
overflow: auto; /* Adds scrollbars only when necessary */
overflow: scroll; /* Adds inactive scrollbars until needed, then activates */
overflow: visible; /* Causes the div to expand to fit the content */
overflow: hidden; /* Hides any content that overflows */
You can use the CSS overflow property: set it to hidden or auto to either hide content or add scrollbars if necessary.
Generally speaking, with large images you want to thumbnail them and not automatically display them, particularly if they're over a certain size.
Using the height and width CSS attributes (or the height and width attributes) will scale the image but it'll still download the whole thing. If its large that could be a problem. It's best to generate a thumbnail on upload, display that and then allow the user to click on that to display the full-size image.
<style>img { max-width: 100% }</style>
This will make the browser resize images to fit inside their containing box. There's a few drawbacks, one being that it obviously won't work in IE6 (maybe 7?), and if the containing element has padding you'll need a wrapper around the image to make it fit.
Another great one although not fully supported would be adding max-width: 400px to your image.
Instead of using CSS, you should do a basic width & height check on your server side, and if it goes beyond a certain threshold use HTML/Javascript to resize the image. Many website forum applications do this and often allow you to click to expand the image.
Then make sure you use the Z-LAYER property to make sure the image floats above content blocks so when the image expands it's above everything.
Automatically resize each of the uploaded images, using a toolkit like ImageMagick. You'd also end up with better looking images, because it'll resample (rather than just resize).
You can then create good looking thumbnails, previews and other sizes of each images that'll fit nicely into your template designs.
If you don't want to go all the way to resizing the actual image file, and want to maintain the proportions of the image, then you can interrogate the image for its sizes (height and width) then multiply them by a required factor to fit into your div.
For example, if you have a 1024x768 image and want to put it in a div that is 800 wide, you know the width will be 800, and the height will be 768 x (800/1024) = 600. Then when displaying your image you can set the height and width properties as required.
or, with some little piece of javascript, you can check for an image width. if is larger than Xpx, then you scale to Ypx. Ofcourse, you will have a little "image flick" until the page is completly loaded.
You can inspire yourself from any IPB forum :)
