Need to set up a responsive (fluid) background image with set height - css

I am helping a friend setup a web site for his company. At the top of the page, below the navigation bar, I have a background image of a house that is set to 100% width, image size is 2400px x 1602px. My problem is how to control the image so that the house is always front and center. I also need to keep the height at (or around) 75vh.
I have tried using background-size: cover and contain, as well as setting background-positions. But with the way cover works, the house is not always centered. Especially when browser width is larger--then only the roof of the house is visible. Next I tried using the aspect ratio of the image for padding. This works well, but does not allow me to set height (as far as I can tell) so with larger screens I end up with the height being way to big.
Was hoping someone might have a suggestion that would help me out and point me in the right direction. What I would like to have in the end is an image of a house where the house is always viewable and also be able to keep the height # 75vh. I have a feeling that media queries may be my answer, but wanted some advice before I continue on that path. Also wasn't sure if I need to crop my image to limit the height? I have tried so many different things that I am not sure how to proceed. Thank you for any suggestion, I really appreciate it.

I think the background cover image is the right approach, you might just have something wron gin your code that is not centering the image and that is why you only see the roof (top part of the image I assume) instead of the middle part in very panoramic screens.
Here is the code I would use:
This is the HTML
<div class="header">Your menu and other header stuff goes here</div>
<div class="bg_image" style="background: url('https://www.marriedwithmoney.com/wp-content/uploads/2017/06/house-1024x698.jpeg') center center / cover no-repeat;"></div>
And this is the CSS
.header {
width: 100%;
height: 200px;
background-color: #ccc;
}
.bg_image {
width: 100%;
height: 75vh;
}
and here is a working example which does what you inted if I understood your situation correctly https://codepen.io/anon/pen/REerRR

setting a responsive background image

I have a navbar and footer than I grabbed and customized from Bootstrap's site. I now want to have a background imagine, but I'm unsure how to do this. I know if I wanted to have just an imagine, I could put it in a div between the navbar and footer and set play around with height:100%; width:auto; so that it resizes with the browser (although this doesn't work perfectly without some modifications) but I don't know how to do this if I have body { background-image: url('...'); } I have a large resolution picture in there right now, and on a 1080 screen it doesn't scale down, it just shows 1080px of the original imagine. Is there anything in Bootstrap or CSS tricks I can use? This might be trivial to some but I am new to this, just finished Codecademy courses which introduced me to Bootstrap and now I'm trying some stuff on my own.
So to recap I want to have 16:9 ratio of a large picture, if the browser becomes to narrow, I want the height to stay the same and start "cutting off" the left/right sides of the image so that the center of the image is still in the center of the browser. Likewise for vice versa. the height:100%; width:auto; doesn't quite work because if the ratio is wrong, it stretches the image.
I also want to have a different picture if the website is accessed from a screen-reader, but that's a project for another day. Let me know if I need to clarify anything, and thanks in advance
Use your CSS this way to make the background responsive.
body {
background-image: url("myimage.jpg");
background-size: cover;
}
Then when the page becomes "too narrow" use media queries to switch the background-size properties to actual width and height that work the way you have in mind.

Fixed background image until bottom of page

I'm trying to get a background image to start and stay in a fixed position, but only until the rest of the 'content' of the page is finished, at which point the full image is displayed.
I'm working on a purely CSS solution. I should note that the image is larger than most (laptop) screens.
Specifically, here's the code that I've been using:
body {
background:$bgcolor;
background-image:url('http://i.imgur.com/cIGSehG.jpg');
background-repeat:no-repeat;
background-position:0px 72px;
background-attachment:fixed;
margin:0;
...
}
The image that I'm using is given in the url():
The effect that I'm looking for is basically the image will display only about the top 10% of the grass hill while you're looking at most of the page, but if you finally scroll all the way down past all the page content, the remaining 90% of the grass hill will be shown.
I couldn't find this anywhere, but I may have just been using poor search terms since I'm not so familiar with the lingo.
Well, this was one jiggy nut! I did come up with a not so stable trick to achieve this. I don't have time to develop it any more right now, but perhaps it might be a working concept.
Main contept
By providing a large and empty footer area that the user is likely to hover when reaching the bottom of the page, we use a sibling selector to change the position of its sibling element containing the background:
#footer:hover ~ #background {
background-position: center bottom;
}
Along with a few quirks (which ought to be improved) we can achieve a parallax effect.

CSS Help Responsive Theme

I'm having a big issue with something so "small" I can't figure it out and I'm reaching out to everyone here. The issue I'm having is this:
I have photos which are roughly 512px or 800px wide I want to fit, CENTERED, in a circle display area and keep my hover effects. I also need to size them the photos so the centered part shows a decent amount of the photo.
The current code I'm working with will make them perfect circles IF the photos are perfect squares. The problem is when the photo is a rectangle, it turns into an oval.
I had created a div like below using overflow:hidden and the css but it conflicted with the current CSS. Any help would be appreciated immensely!
.thumby {
width:200px;
margin: 0 auto;
overflow:hidden;
position: relative;
height: 200px;
border-radius: 100% 100% 100% 100%;
}
img.absolutely {
left: 50%;
margin-left: -256px;
top: 50%;
margin-top: -200px;
position:absolute;
width:512px;
}
Here's the link to my dev pages.

have you thought about setting the image as the background of the div? This way you keep all the effects you already use and there are ways to manipulate the background position without affecting the outside div. Other possible solution to have perfect round divs, is to use the ::after pseudo-class, like in this gallery tutorial:
http://webdesignerwall.com/tutorials/decorative-css-gallery-part-2
Sorry if I misunderstood you, hope it helps.
PS.: Beautiful test page by the way.
Well first, you'd only need to set the border radius to 50% to make something a circle, and if each corner is the same value, then you can just enter it once like so:
border-radius:50%;
As far as these images being rectangles goes, you could set your images as the background of a span, give it a height and a width that forms as square and use display block. This would keep the photos proportional, but allow you to make them square.
This however, could create a bit of a markup mess if you have a lot of images to display. Another solution, which means more work, but I would personaly do it, is to just crop your images into squares for their thumbnail with photoshop or some other image editing tool.
Above all of that, I don't see a width or height actually declared on the pages you linked. Are you sure you've placed them on the correct class? I see the border radius declared, but I'm only seeing a max-width: 100%; not width: 200px or height:200px
I re-thought the problem with the suggestion of using the images as backgrounds of an element as madaaah did above.
What I ended up doing was wrapping a DIV around my A tag like this:
then, I set the background of the A like this: style="background:url(PHOTO URL HERE) no-repeat;background-position:center;">
lastly, I made a square image (800 x 800) to go inside the A tag so it would keep the round shape and made it completely transparent so the background image is visible, while growing and shrinking in a "responsive" manner.

background image surrounding content shifts with scrollbarr

I am trying to use a background that surround the content area (just a bit of shading on both sides) as seen here: http://i.imgur.com/5X5D7.jpg
I left room in the middle for the fixed width layout which is 980px.
My body css is just this:
body {
margin: 0;
padding: 0;
background: url(../images/bg.jpg) center repeat-y;
}
It looks good on the homepage that has no content on it. But when I go to a test page that has a few paragraphs typed out and the scroll bars appear in my browser, there is a slight white line that appears to divide the background and the content area.
I tried shifting the background image shading by a pixel but then it does not work on the homepage..
Is there something else I can be doing in the css to prevent this?
I should say I am trying this in drupal with the zen theme and have not really changed anything else.
Made a jsfiddle for you: http://jsfiddle.net/Ja2SR/
Essentially I think you're looking at the browser trying to divine 1px in two, which it can never do. I don't really understand why it is an issue, though - the line appears inside the content area, which in the fiddle you can see as white next to red, but if your content area is white also, and has padding on both sides, which I assume it does... then having 1 more pixel shouldn't be too bad. Correct me if I'm assuming wrongly!

Max-height (and aspect ratio) issue in Chrome, when I want to make an image gallery with floating height

A few weeks ago I working on this site. This is my next portfolio site. I want to make this structure, when I finish:
Header
Horizontal image gallery with floating height
Footer
I want to create something similar, just like the 22slides.com portfolio sites for photographers. If you change your browser's window size or press full screen button, the img element or the image's div automatically change his height.
I putted in the CSS a "max-height" parameter, to prevent the images never become bigger than their original resolution. It's a serious issue on huge resolution screens. but in Chrome it's not working properly, because the aspect ratios become wrong. If you press full screen, the aspect ratio more bad. In every other latest browser (Firefox, Safari, Opera, IE8-9) working normally. I created a custome CSS only for chrome with this command (but now I uncommented this in HTML to show you the Chrome aspect ratio problem):
#portfolio img { max-height: none; }
So with this line, the images using the biggest possible height in Chrome and the aspect ratios are correct. But it's a problem for me. I not want that a 1024x683px image showed bigger than his actual resolution on a FullHD monitor.
I think the best solution, if there's a javascript, which is dynamically escribe a width and height for every single image and keep the original aspect ratio. 22slides.com using something similar javascript, but I'm not a javascript programmer at all. :(
The images HTML structure:
<div id="portfolio">
<img src="image1.jpg" alt="" />
<img src="image2.jpg" alt="" />
</div>
CSS (max-height is very little number, just to show you the problem in Chrome):
#portfolio { white-space: nowrap; float: left; }
#portfolio img { height: 100%; width: auto !important; min-height: 150px; max-height: 350px; }
I'm using this Jquery Javascript to dynamically change the image's height and bring back the image's overflow on the screen with 130px negative height. Probably not this script causing the problem, becuase if I turn it off, the aspect ratios are more bad in Chrome:
// Dynamical vertical resizing on images and Correct the height (to not overflow the screen)
$(document).ready(function(){
$(window).load(function(){ // On load
$('#portfolio img').css({'height':(($(window).height())-130)+'px'}); // Adjust the number if you change something in CSS
});
$(window).resize(function(){ // On resize
$('#portfolio img').css({'height':(($(window).height())-130)+'px'}); // Adjust the number if you change something in CSS
});
});
I need help! Thank You!
Update:
This javascript written by "Emphram Stavanger" and "nick_w" seems to solve my image fit to browser height problem:
Imagefit vertically
I tried and it's perfectly working with one single image. The image fitting in the available viewport window perfectly, with correct aspect ratio! There is a visual explanation for our problem made by "Emphram Stavanger":
http://www.swfme.com/view/1064342
JsFiddle demo (Basicly it's Emphram Stavanger's code, I just putted in the changes by nick_W, changed Jquery to latest and I putted after the show link:
http://jsfiddle.net/YVqAW/show/
I not tried yet with horizontal scrolling image website, but it's already a big step!
UPDATE 2:
SOLUTION: https://stackoverflow.com/questions/20303672/horizontal-image-slideshow-javascript-not-working-properly-with-portrait-oriente
(And I need help again...) :)
A little late but you can use a div with background-image and set background-size: contain instead of an img tag:
div.image{
background-image: url("your/url/here");
background-size:contain;
background-repeat:no-repeat;
background-position:center;
}
Now you can just set your div size to whatever you want and not only will the image keep its aspect ratio it will also be centralized both vertically and horizontally.
The background-size property is ie>=9 only though.
