So I've been trying to create a simple page where the image takes up 100% of the height, with a small sidebar. I want the image to resize itself when I resize the window. When I resize the window vertically, the width stays the same, which is not what I want (I want it to retain it's aspect ratio whatever the window size). I really dislike this distortion, but am unsure of how to fix it. Any idea what I'm doing wrong?
.big-image {
max-height: 100%;
min-width: 20%;
margin: auto;
overflow: hidden;
}
set display: block or display: inline-block to your .big-image class, in order for the max-height and min-width property to work. These properties, along with height, width, min-height, max-width, padding-top, padding-bottom, margin-top and margin-bottom doesn't work on inline elements.
You can set either the height or width of an image to auto and control the other property with a set size whether that be percentage or px. That auto should maintain the aspect ratio of the image while you get to control the size of the image with the other property.
max-width:100% and height:auto will work. When applying max-width:1000%; it will take the width of the container and height will be proportionately varied.

I have an image which width should be as large as possible and I want it's height to not exceed the height of the parent while also maintaining the aspect ratio of 16:9. The issue right now is, it works well till the screen size is 1591px, if it gets bigger than that, the height exceeds and the vertical scroll bar appears. I don't want that behavior. How can I achieve that?
the scrollBar appears because of the overflow you can do 2 things
use the "overflow: hidden;"
body{
overflow: hidden;
}
you can use max-width to determine the max-width of the element and set it on both of the elements
I hope it was helpful 😁
UPDATE: the original answer assumed from the question that the image was an HTML img. The solution was to set width to 100% [of its container] and height to 70vh and use object-fit.
However, it is not an img it is a canvas.
The required aspect ratio is known to be 16 / 9. This snippet therefore sets the max-width to 100% (of whatever is the container) and the max-height to 70vh.
This way there can never be any overflow and the canvas will be as big as it can be within those constraints.
body {
width: 100vw;
margin: 0;
}
canvas {
max-width: 100%;
max-height: 70vh;
aspect-ratio: 16 / 9;
background: green;
}
<canvas width="1600" height="900"></canvas>
I can't get this simple slideshow to re-size correctly. When I shrink down the window, the image width compresses, but the height does not, and I want the height/width ratio to remain the same as the viewport shrinks. I know the fault lies somewhere in my CSS, and but I can't track down the issue. Any help appreciated.
Just use height: auto
.slides img {
height: auto;
/* Rest of you code */
}
I have a set of logos of variable size. I've set them all up at the same height of 50px with a width of auto:
.img-logo {
width: auto;
height: 50px;
}
This works fine until the window is resized. When the window is resized, wider logos flow outside of their container.
I would like the logos to shrink to fit their container width. I have tried to achieve this with max-width:
.img-logo {
max-width: 100%;
width: auto;
height: 50px;
}
This works but the aspect ratio is compromised due to the height property remaining 50px.
Any ideas?
With a fixed height and variable width either of the below can happen.
The img gets stretched to accommodate the variable width and skew the aspect ratio.
The img gets cropped (overflow:hidden) by the parent but the aspect ration is kept intact.
So you can make the img responsive too. But then it wont have the constant height, while keeping the aspect ratio intact.
I think it's impossible to keep its size when the window is too small and you didn't want to change ths size of image. Why not try #media,which can provide different css styles in different conditions.
I have an image something like below.
<img src="file.jpg" />
Below is the css code
img {
max-width: 100%;
height: auto;
}
Can anyone explain me on how does this css code make the images responsive, I mean scale it perfectly. I want to know the working behind this css code.
When your parent width is smaller than width of image, image width will take 100% of parent width.
If parent width is bigger than image width, image width will stay original.
Same with max-height. Also min-width/min-height will ensure that width/height will not be smaller than specified.
height: auto; will preserve aspect ratio for image. If you set both max-height and max-width or set height to specific size than image will be stretched
When you apply max-width:100%; to any element then that perticular element could have maximum 100% width of its parent, thus it can give you gaurantee that child will never go out of parent's bounds.
Thus if parent has suffitient width then child is shown in it's original size, otherwise it's width is matched to the parent. Thus it make our layout responsive.

I have a video element set to 100% width in a container div. That div has a max-width of 800px and min-width of 400px. When resizing the browser I need the video element to resize while retaining its original aspect ratio. Currently it resizes in width but remains its original height, adding letterbox bars above and below to make up for it.
Is it possible to resize the video element dynamically like this without resorting to Javascript?
According to the box model, in the section on replaced elements, this should work as you expect: Since the video has a height of auto and a set width, and it has an intrinstic ratio (as videos do), then the used value of height should be computed based on those. Make sure you are not specifying the height anywhere — the following CSS worked for me:
video {
width: 100%;
}
div {
max-width: 800px;
min-width: 400px;
}
Try explicitly adding height: auto to the video — maybe with !important to see if it’s getting set somewhere else.
