Responsive background image in div full width

I'm trying to figure out how to make a background-image in a div full width and responsive. The background-image is expanding across the width of the page (and is responsive), but the height of the image isn't its full height. It seems like it's being cut-off somehow. I'm using bootstrap framework, and the reason I'm trying to do this is I want to overlay some text on the image.

I've got three background images, all of width 643px. I want them to be set out like so: top image (12px height) no-repeat middle image repeat-y bottom image (12px height) no repeat I can't seem to do it without getting them to overlap (which is a problem because the images are partially transparent), is something like this possible? background-image: url(top.png), url(bottom.png), url(middle.png); background-repeat: no-repeat, no-repeat, repeat-y; background-position: left 0 top -12px, left 0 bottom -12px, left 0 top 0; Your problem is that the repeat-y is going to fill the whole height, no

I've got a div and apply :before and :after an image as content. That works perfectly. Now I would need to apply a background image so it does repeat as the div resizes, but it does not seem to work.

问题 I'm trying to modify an existing webpage by inserting my own Javascript file in it. I'm setting a background Image for this webpage by inserting a new Div through my Javascript and setting background of that div to image url. For centering this image on background and to make it occupy the whole webpage, I'm using 'background-size': 'cover' property. This of course doesn't work in older IE versions. I want to fix it, I'm thinking of zooming in the image by specific ratio calculated using page

问题 I have a div with a background image that will overlay part of the header slideshow. I want the width of the div to always be 100% of the window size, even when the user re-sizes it. The height should change based on the aspect ratio of the background image. The dimensions of the background image is 1500x406. Here's the sample code: HTML <div id="wrapper" class="clearfix"> <div id="bg_img"></div> </div> CSS .clearfix { width: 100%; position: relative; display: block; margin: 0; padding: 0;

This question already has an answer here: CSS background image alt attribute 10 answers How can I display text instead of logo, if the logo graphic file isn't loaded or missing?
