Is there a way to determine the height of a background image when it's being used as a responsive image?
IOW, I want to know the height of the background image at a specific screen-size (but I don't know the actual screen size because that's the responsive part).
I know how to find the height of the image via the actual image file, but that's not the same thing as the image's height within a particular screen size.

For example, if I have a background image of a cyclone and it's responsive/resizes with the window and covers the whole web page (background-size: cover), but the eye of the cyclone isn't in the center of the webpage but say slightly more to the right and I wanted another image, say a picture of an apple, to always cover the eye of the cyclone, no matter what size the window is, what could I do?
I've tried playing around with the margin percentages, the image of the apple is also responsive and shrinks with the background image to cover the eye of the cyclone but the images always tend to move out of sync just before I've dragged the window to it's smallest size.
The CSS background size property can have value of cover. The cover value tells the browser to automatically and proportionally scale the background images width and height so that they are always equal to or greater than the viewports
width/height.
In Img tag use height i and width in pixel then change in CSS
then output will show properly
Check the Multiple Backgrounds CSS feature which will achieve your request: https://www.w3schools.com/Css/css3_backgrounds.asp
I'm working on a website. There's one problem. The slider won't fit in the frame without stretching.
Slider Image is full width of screen and i have defined height for it.
In CSS part i have applied object-fit: cover but this crop my image
I hope you guys can help me out on this. I'd tried alot and also asked some other people but they can't help me with this.
Or Should i restrict my client to use image of that resolution only?
Yes Mostly you should restrict the client from using different ratios, or resolutions, because you are using the full width aaaaand defined height, defined height is very limiting in your case, what you can do is use
object-fit:cover;
object-fit:center;
but that doesn't stop the cropping it will just focus on the center of the image when cropping.
I have an image . i want to make it a body background image but the image is stretched all the solutions i found so far on internet to resolve this problem and maintain aspect ratio lead to cropping image and this is what happen when setting (bg-size : cover) the image aspect ratio is maintained and it fill the page but the image is cropped
so Q here is how i change any image width and height values without stretching or cropping it .......
first one is original , second is stretched third image is cropped
What you are asking for is impossible - for the image to cover the entire screen/window without cropping or stretching, it would have to have the exact same dimensions as the screen/window.
I'm validating my HTML 5 pages and I get a lot of errors because I specified the width and height of my images in percentage. I though that this was the best way because if I specify it in pixels it won't resize when the site is viewed on a smaller device.
What's the correct way to specify the width and height of an image in HTML?
Thanks
If the original image is the aspect ratio that you want then just specify the with % and the height will change automatically. Make sure that the height of the parent div does not have a specified height as that may cause some problems. Also positioning of the rest of the page should be relative.
So I have a horizontal banner that I defined via a div. This div has a width of the full window and fix height of 500px for the time being. How can I scale an background image (2048 x 1283) to fill the div entirely without loss of picture quality? How would I do the same if the div height was relative to the window size, perhaps 25% or 50%? I want this to work when the window is resized.
Well you will never loss picture quality because you are keeping rendering the same picture over different sizes. You have to understand that responsive background its a hard topic since the picture will never display exactly how you want to, since different devices will have different display resolution, as example if you are seeing the same responsive image in your iphone portrait format (vertically) will look smaller in height than if you see in the same device but in landscape format (horizontal).
Any way heres is a question that can help you in your journey of responsive backgrounds Responsive css background images
cheers.
