7/3/2023 0 Comments Resize background image css![]() In order to get this inline image to behave more like a background image, we can use that unique class we applied to apply some absolute positioning. We can also do this (FTW) any time the window is resized. We will need to do this as soon as the DOM is ready so it happens before the image even starts loading. Then we’ll use that number to set the width attribute on the image, which we’ll give a unique class name “source-image”. The background-size CSS property lets you resize the background image of an element, overriding the default behavior of tiling the image at its full size by specifying the width and/or height of the image. We can, again, use jQuery and the dimensions plugin to get our browser window’s width. If we can get our hands on the exact pixel width of the browser window, we can use that number in the width attribute of the image and control its size while retaining the ratio. With the img tag, we can set “width” and “height” attributes to control the image’s size. In order to control the size of an image displayed on the screen without literally altering the file itself is to display it inline with the tag. While the first attempt did a decent job, it failed at the most fundamental level: it wasn’t “resizeable”. The above code will hide the image on the page, but snag it’s “src” attribute and apply it as a background to the body element (via its unique ID “page-body”). 'backgroundImage': 'url(' + $source +')', Var $source = $("img.source-image").attr("src") Here is how I went about this first approach. Pretty good solution I thought, even if it isn’t technically resizeable, since you can’t set the size of a CSS background-image. If applied to the body tag, this will fill the screen nicely with no scroll bars. Large browser windows will reveal more of the picture and smaller ones less of the picture. ![]() It also can be centered, so I figured this would be good enough. This will fill the screen edge-to-edge if the image is big enough. Well my first thought was that this really needs to be a CSS background-image. It also meets all the other requirements: no scrollbars, and retains pixel ratio. It doesn’t do it “on the fly”, but it does work. Go ahead and resize your browser window around and notice how the image will resize to fit. First, check out the finished project, then I’ll show you how it was done:įinished Project: What’s The Weather? Offline Ultimately, I found a pretty good solution and we turned it into a pretty neat little project. But of course this is just the kind of challenge I enjoy, so I set about to thinkin’. Also, comes in on the page as an inline tag. Also, doesn’t cause scrollbars, just cuts off vertically if it needs to. Also, make sure it retains its ratio (doesn’t stretch weird). Also, have it resize larger or smaller as the browser window changes. Is there a way to make a background image resizeable? As in, fill the background of a web page edge-to-edge with an image, no matter the size of the browser window. My friend Richard recently came to me with a simple CSS question: If you are looking for how to do FULL SCREEN BACKGROUND IMAGE, go here. The background-size property values could be keyword values, unit values (such as percentages or pixels), or global values (such as those in the below code block). The image can be left at its original size, stretched, or limited to fit the available space there are numerous variations and syntaxes to set these behaviors. ![]() The CSS background-size property determines the size of a background image for an element. ![]() When he's not meddling with CSS, he spends his time writing, sharing what he knows, and playing games.
