Div overlay on a responsive image - html

http://jsfiddle.net/LFtHg/
I'm trying to create my first responsive website. For this, I'm including an image. This image has a caption which should be displayed in a transparent overlay. However because opacity settings are passed to child elements, I have removed the text from the container.
I cant get the overlay to display, at all (because it has no content inside it). I cant really add a fixed height as I want to image to respond to changes in browser size. How can I ensure this is displayed?
Thank you,
J
Edit, also what would the best way to scale the overlay as the browser resizes. I'm unsure if this approach is even possible.

First of all, you can use an RGBA background ( background: rgba(0,0,0,.5); ) instead of using opacity.
Secondly, you need explicitly set a width for your span.figcaption (you can also do that by specifying both left and right offset properties)
Perhaps this demo http://dabblet.com/gist/2778608 might also help you (image can be of any size - resize the browser window to see how everything resizes).

Adding the following rules to your existing sample effectively stretches the .figcaption elements to fully cover the .figure, fiddle:
.figure {position:relative;}
/*these could be different so that the overlay appears larger than the caption*/
span.figcaption {position:absolute;top:0;right:0;bottom:0;left:0;}
p.figcaption {position:absolute;top:0;right:0;bottom:0;left:0;}
You can arbitrarily adjust the values to a % setting so that the caption appears centered etc.
BTW, you know that your implementation is not yet liquid, right?

Show specific part of background image

I'm having a little problem with one of my background images in a div element. I'm using the following CSS:
.myBox
{
background-image:url('....');
background-repeat:no-repeat;
background-size:cover;
}
My background image is a picture with some people on it. Now, if I increase the width of my browser window, at a specific point, some of the people are cutted off (due to the automatic resize of the image with 'background-size:cover').
My question is: Is there any option (or jQuery plugin), to set a specific part on the background image that will be always visible on all window sizes and also fill the whole element?
There are a variety of solutions you could try; however, you might want to start with something simple like applying a background-position.
https://developer.mozilla.org/en-US/docs/Web/CSS/background-position
Using the background image of the group of people as an example, you might set background-position: top so that their heads never get cut off. You can also set the vertical and horizontal position in pixel or percent units.

Image stops scaling after certain resolutions

I'm trying to understand why on a webpage I'm working on the image stops scaling once it reaches a certain resolution. You'll see what I mean if you manually adjust the browser size here: http://bit.ly/1nnzqeB
Can anyone help deduce what is causing this?
Because the maximum zoom percentage is limited. In case of chrome it is 500%
Sorry to say, but it may be impossible with your current approach.
I highly recommend going for an approach without using the CSS attribute of background if you always want it to be 100% of the view-port width. Use an img tag instead. You are already using Bootstrap (by the looks of your demo). So use an img tag and give it the class of img-responsive.
DEMO WITH BOOTSTRAP
Here is an example with your image and how you could implement it into your project. If you need to place any text over the image (like in your example), just make the div or heading tag have a higher z-index with either a position relative or absolute. I can provide an example if you need it.

Images not showing in Chrome until I click inspect element

I have encountered a strange bug using my OpenCart website in Chrome. The product images are not showing up but I see the white area where they should come.
If a product doesn't have an image it's aligned to the left but in this case I can see the white area where the picture normally is.
And here's the crazy part, if I click on inspect element, suddenly the image appears.
Some css code
.product-list .image {
float: left;
margin-right: 10px;
overflow: auto;
}
In the CSS you need to set the width and height attributes.
That is weird. Regardless, things to check:
Z-index: The outer box that surrounds the image might be "above" the image itself. Add z-index to the image with a value of 9999 to check
Position: if it's parent container or god knows what else has a weird position it could be affecting where the child element, in this case an image is appearing.
Disable JS - Javascript might be causing an issue here, try disabling it to check.
Also, when you use chrome dev tools, you are technically "hovering" on the image. And you say it suddenly appears. So I'd take a look at your :hover rules as they apply to images. A lot of sites will use a sprite technique that shows one image in normal state, and then shift the background to a different part of the same image on hover. Your normal state could be empty and the hover then moves the bkgd position to the image you want.
Let me know how this turns out.
More scenarios to replicate this issue
1. Close inspect if not already opened.
2. Resize inspect if already opened.
3. Resize browser window.
Just to follow up on this issue, Mary's answer is the correct one, but for our circumstances it was important not to set a width and height in order to maintain responsiveness. But apparently setting width and height to auto works just as well, even though it makes no difference in appearance.
So, since opening the Web Inspector resizes the page in some cases, you should look into:
resize handlers on JavaScript side that might be causing your images to show up
media queries that satisfy certain width and only show images then on CSS side
Picture element having media queries that
aren‘t covering the width you are viewing this with.
For me this was the Picture element having a gap in its media attribute definitions (<source media=(min-width: 1824px)">).

Layout issues, part fixed width, part elastic

I've already had a look through some posts and couldn't find what I was after. I'm designing something in PS at the moment and I can foresee an issue when it comes to coding the design into html+css.
Imagine my centre div, it's 960px. It's going to have a semi-transparent .png as a background. The design is “full width” so this div will be contained in a larger div, set to 100% width. This is all ok until I get to the background on this outer div. It's also going to have a .png running the full width of the page. Problem is: I don't want it running through the middle, as it will result in the middle have a double thickness to it, if that makes sense?!
Basically, I need a way to either run a div either side that is elastic, or someway of stopping the background from running across the centre 960px portion of the browser window.
I have NO idea how this can be achieved, apart from using JS to set widths, which I don’t really want to do.
Any ideas?
Ok, I’ve tried to get the basic issue here: http://jsfiddle.net/8Bznc/1/
You can just put a non-transparent background on the center div, so the other background doesn't show through.
See here: http://jsfiddle.net/9bnHD/
Apply the background-image only to the wrapping div.
Alternatively, if the center and sides need to have different images, give the center div a non-transparent background-color as well.
Also, you could fake it by using multiple background-images. Demo
Keep in mind this won't work in old versions of IE, but something as non-essential as background transparency can be excepted as graceful degradation.

CSS div shifting elements down

I am working on my portfolio and I am having an issue with the project description shifting the images on the left downward when the browser resize. A picture of the issue here: click here When you resize the browser the text will shift over and move the images down. I've tried setting min-width but that doesn't help the text nor the image div to make sure it doesn't resize at a certain point.
Here is a sample link to the page itself: [click here][2]
I tried adding min-widths to a image element but that doesn't work either. I do not want to use absolute position as it will overlap on top on resize. Any thoughts or suggestions?
You have an image that is 1052px wide, which is in a UL element that has a margin-left of 1.5em. Your description box is 350px. Basically your #imagewrapper div needs to be equal to or wider than all of these elements.
Right now that's about 1422px. It will change if the effective font size for your UL.imagewrap-pad changes.
That's a pretty wide web site. You probably should make it a bit narrower if you're making it for general viewing, especially with all the tablets etc out there now.
Anyway, the code you want is
#imagewrapper
{
width:1422px;
margin:0 auto;
}
The second line makes it center on the screen.
P.S - get Firebug for Firefox, or use similar tools in chrome. They let you endlessly experiment with styles to find out what works for you.
To solve the problem just set the "width" property in #imagewrapper :
#imagewrapper {
width: 1430px;
}
Have You tried setting up width attr on the parent element to around 1800px?
div#imagewrapper {
width:1800px;
}
It will put a scroll bar at the bottom of Your browser, but if You want to put such a big image beside that text then You do need a lot of space. Just keep in mind that it won't fit in users monitors.
To make it look nice I guess You should apply that attribute to the body tag.
