We’ll set some basic visual styles for the card itself, a quick update to the expected h3 headline, then essential styles to begin to style the card image. Next, we’ll create a minimal set of baseline styles for the. Dans cet article, nous allons préciser le concept dimages adaptatives images qui sadaptent aux appareils selon les différentes tailles décran, résolutions et autres caractéristiques de ce type et examiner les outils fournis par HTML pour faciliter leur mise en uvre. But we’re going to explore two modern CSS properties that don’t involve extra math, give us more flexibility, and also allow keeping the semantics provided by using a real img instead of an empty div.įirst, let’s define the HTML semantics, including use of an unordered list as the cards’ container: You may have also used this idea to maintain a 16:9 ratio for video embeds, in which case the padding value is found with the formula: 9/16 = 0.5625 * 100% = 56.26%. Setting a padding value as a percent results in a final computed value that is relative to the element’s width. One advantage this has is using an older trick for aspect ratio which uses a zero-height element and sets a padding-bottom value. If it is within an article, it will take up 100 of the article width. Setting the width makes the image to adapt to its container. I’ve implemented this solution many times myself in the past. The easiest way to make images responsive is defining the width for the element.A consequence is uneven positions of the card content which really stands out when you present a row of cards.Īnother previous solution besides cropping may have been to swap from an inline img to a blank div that only existed to present the image via background-image. And while this can be resolved by cropping ahead of time, we can still encounter issues due to responsively sized containers. The common problem with this setup is that we may not always have perfect control over what the image is, and more importantly to our layout, what its dimensions are. To prepare for our future image effects, we’re going to set up a card component that has a large image at the top followed by a headline and description. The newly supported aspect-ratio property in combination with object-fit provides a remedy to this headache of the past! Let’s learn to use these properties, in addition to creating a responsive gradient image effect for extra flair. A classic problem in CSS is maintaining the aspect ratio of images across related components, such as cards. This is easily achievable with something like this without touching any of the JS code for resizer. Changing height would proportionally change the width of the image instead as it does now already and the proportions would stay thanks to height: auto. To get a simple fix (at a cost I'll get to later) assuming we are working with static/relative images we can override setting height and just force it to be always auto and force max-width to be 100%. This could have caused images to have non native aspect ratio causing the image to deform if max-width was set or leak beyond the container if it wasn't. If I make width 20% smaller, height will get 20% smaller as well and they will be set as width/height CSS properties. It's possible to fix this fairly easy but it would affect what outcomes are possible with the resizeable box component if we did not change the unit system for the resizer from absolute (px) to relative units (%).Ĭurrently, when width/height are changed they are changed proportionally. Edit: yeah there doesn't seem to be a trivial fix to this one, per the commentary above. Meanwhile, I'll tinker a bit with the max-width and a percentage value, see whether I can get it working. But given that #38399 fixes it on the frontend, we might want to see if we can land that one, and repurpose this ticket to detail the bug in the editor. So it seems like at worst this can only be fixed in the editor with a little bit of a refactor. It would be good to revisit this once a content-width variable in most cases, allow you to scale the image beyond the width of the vanilla style, so 3rd party themes have some wiggleroom. The following variable adds a buffer to this set the content-width, this max-width is currently dictated by the explicit pixel value for the max-width. With the current implementation of ResizableBox, an image needs an
