问题 Whilst trying to make an image fit into a rectangle, I came across a weird problem and wondered if anyone knew why these three ways of using object fit act differently: .container { width: 250px; padding-top: 20%; border: 1px solid red; position: relative; display:inline-block } .container>img { position: absolute; top: 0; left: 0; object-fit: contain; object-position: center center; } .image { width: 100%; height: 100%; } .image-1 { right: 0; bottom: 0; } .image-2 { right: 0; bottom: 0; max

3 月，跳不动了？>>> object-fit和object-position是我最近最喜欢的两个CSS属性。他们使开发人员可以操作img或video中的内容，类似于我们可以用background-position和background-size操作背景内容一样。 首先，让我们深入探讨一下object-fit 该属性定义一个元素，如img，如何适应容器的宽度和高度。我们可以用object-fit告诉内容以各种方式填充容器，如“保存该长宽比！” 或“向上伸展，尽可能多的占用空间！” 这里有一个案例: 这张图片的大小为400px x 260px。如果我们这样给图片设置样式... img { width: 200px;height: 300px;} ...最后图片失真，因为图片为了适应容器已经被压扁。 当我们改变了img的高度和宽度时，img的内容将占用我们所创建容器的所有可用空间，从而破坏了之前创建的的长宽比。 为了保持图像的长宽比，同时也可以填充空间，我们可以使用object-fit： .cover { object-fit: cover;} 左侧是我们原始的图像，右侧图像已裁剪原图像的两侧以保持我们现在的长宽比！这看起来没什么特别之处，但一旦进入到缩放设计，那么object-fit就立马彰显其真正的威力。 让我们看另外一个案例: 在这里，我们有两个图像

问题 I have been unable to find any documentation to tell me one way or another. Am I able to use object-fit cover on a canvas elements? I have done some experimenting and it is not behaving as expected. Can somebody give me a definitive answer? 回答1: object-fit 1 will only work when there is a ratio change in order to correct it. Here is a basic example: var canvas = document.querySelectorAll("canvas"); for (var i = 0; i < canvas.length; i++) { ctx = canvas[i].getContext("2d"); ctx.fillRect(50, 50

CSS object-fit: contain; is keeping original image width in layout

I'm trying to make my images responsive inside some flexbox containers using object-fit: contain , and while the images do resize, the layout seems to be keeping the original image size, causing a scrollbar to appear. Checking the width of the image using Chrome Dev Tools shows that the width is still 1024 (however the height has been reduced appropriately.) (I've taken inspiration from Auto Resize Image in CSS FlexBox Layout and keeping Aspect Ratio? to get to this point) Am I missing some additional CSS attributes? JSFiddle: https://jsfiddle.net/w6hgqf18/1/ html, body { margin: 0; height:
