content description in the http://www.cnblogs.com/2050/p/3877280.html article: In the mobile browser and in some desktop browsers, the Window object has a Devicepixelratio property, which is officially defined as the ratio of the physical pixels of the device to the device's independent pixels, i.e. Devicepixelratio = physical pixels/independent pixels.CSS pixels can be viewed as independent pixels of the device, so by devicepixelratio we ca

Google's mobile phone map has been heard of for a long time and occasionally used it, but it has never been used carefully, because I am too familiar with maps and have no habit of using the mobile phone network, so they are all casual games. I just got a good mobile phone today, with a super high pixel and a Windows

One, why there is a pixel problemTo understand this problem, we must first know the DPR.The DPR (device pixel ratio) pixel equals the picture element. Device pixel ratio, which is the default scale of 100%, that is, the number of dpr= device pixels/The number of ideal viewport pixels (device-width).1. Device pixels: ph

Due to the problem of mobile phone DPR (device pixel ratio), there are often 1 pixel border problems in WebApp, the solution is as followsThe following code implements BORDER-1PX ($color) {position:relative using sylus ; :after{ Display:block; Position:absolute; left:0; bottom:0; border-top:1px solid $color; Content

Since the amid Lord has raised the retina screen. Can have a lot of front-end brothers of the pixel eye, obsessive-compulsive partners days can be suffering. To draw a true 1-pixel border, the front-end apes were abused by browsers.About what is the mobile side 1 pixel border problem, first on the two pictures, we will

In a mobile Web project, the following 1-pixel border is often implementedMobile Web design, the retina display under the screen will be 1px will be rendered as 2px, then the visual version of 1px lines to restore the page needs CSS defined as 0.5pxBut just as we go to use 0.5px to Boder to find the CSS border-width:0.5px does not work, that is not really support 0.5px it?Some of the problems we found when

DPI (DPR) stands for dots per inch which technically means printer Dots per inch.This parameter actually quantifies the physical resolution and display sharpness of the screen, such as the iphone's DPR 2, which is higher than the average phone.The same images have a very different effect on different phones, especially for Apple devices, because their DPR are relatively high, so they generally have toApplication of high resolution image display can be

Google's services must be obvious to all, and they are really excellent. Since mobile devices such as mobile phones can greatly facilitate our lives, why not enjoy Google's services on mobile phones. However, most of Google's services are on the computer. What services can we enjoy on our mobile phones? Let's take a lo
