The media query syntax is reminiscent of the animation keyframes syntax, as it defines a block within the CSS, in which you write additional CSS rules that are only applied in certain cases.2017 13 Macbook Pro Retina - 2.3GHz i5, 8GB RAM, 128GB SSD, 1YR COVERD. These blocks are called media queries. We need to write blocks in our CSS that will only be used by devices that match that block’s criterias. The Chrome emulation is a helpful tool as well as it kicks in media queries.media queries.The Retina Asset Workflow You’ve Always Wanted For Photoshop A Better Way To Design For Retina In Photoshop Further Reading on SmashingMag: In the absence of industry-wide standards to streamline the process, each Web designer and developer is left to ensure that their users are getting the best experience, regardless of the display they are using. By contrast, the Web is a gargantuan mass whose very open nature makes the transition to higher-density displays slow and painful. 1,399.In the confines of Apple’s walled garden, popular native apps get updated with Retina graphics in a timely fashion, with the help of a solid SDK and a well-documented transition process.Generically, CSS pixels are referred to as device-independent pixels (DIPs). CSS PixelsA CSS pixel is an abstract unit used by browsers to precisely and consistently draw content on Web pages. Apple has coined the marketing term “Retina” for its double-density displays, claiming that the human eye can no longer distinguish individual pixels on the screen from a “natural” viewing distance. It is often measured in pixels per inch (PPI). Each and every pixel sets its own color and brightness as instructed by the operating system, while the imperceptible distance between these tiny dots takes care of tricking the eye into perceiving the full image.Screen density refers to the number of device pixels on a physical surface. Free Photoshop Action For Slicing Graphics For HD ScreensBefore diving into the nitty gritty, let’s briefly cover some basic notions that are key to understanding the challenges and constraints of designing for multiple display densities.A device pixel (or physical pixel) is the tiniest physical unit in a display.
![]() Making Media Queries Laptop Retina Display Full Size On AThe Tool ChestEven though we are still in the early stages of this major shift, several approaches to optimizing Web graphics for Retina displays have sprung up, and more are popping up as we speak. Because a bitmap pixel can’t be further divided, it gets multiplied by four on Retina displays to preserve the same physical size of the image, losing detail along the way.Each bitmap pixel gets multiplied by four to fill the same physical surface on a Retina display. The browser squeezes or stretches the image based on its CSS height or width during the rendering process.When a raster image is displayed at full size on a standard-density display, 1 bitmap pixel corresponds to 1 device pixel, resulting in a full-fidelity representation. Open a my passport for macOn a standard-resolution display, the result would be an image rendered with four times fewer pixels than its full bitmap size — a process commonly referred to as downsampling.A CSS-sized image gets its dimensions halved during the rendering process.Because the same image would use four times as many physical pixels on a Retina screen, every physical pixel ends up matching exactly 1 bitmap pixel, allowing the image to render at full fidelity once again.CSS-sized images regain their full-detail glory on Retina displays.There are several ways to achieve this: Using HTMLThe easiest way to apply CSS sizing would be by using the width and height attributes of the img tag: Please note that, even though specifying height is optional, it allows the browser to reserve the space required for the image before loading it. For instance, to serve a 200 × 300-pixel image (remember, those are CSS pixels), you would upload an image with a bitmap resolution of 400 × 600 pixels to your server, then shrink it by exactly 50% using CSS properties or HTML attributes. HTML And CSS SizingThe most straightforward way to serve Retina-ready Web graphics is to halve the size of your raster assets using CSS or HTML, either manually or programatically. As such, choosing a tool should be done case by case, taking into account both quantitative and qualitative factors. With the help of jQuery, this would look like this: $(window). Using JavascriptThe same result can also be obtained using Javascript by targeting all Retina-ready content images in the document and halving their sizes.
