value can be obtained according to the following formula: Device pixel ratio = physical pixel/device independent pixel // on one side up, x direction or y direction In javascript, you can use window. devicePixelRatio to obtain the dpr of the current device. In css, you can use-webkit-device-pixel-ratio,-webkit-min-device-pixel-ratio, and-webkit-max-device-pixel-ratio to query media, make some style adaptation for devices of different dpr (here only for browsers and webviews of the webkit kernel

a certain understanding of the TCP/IP protocol. POP Protocol IntroductionPop stands for post office protoco, which is the post office protocol used for email reception. It is now commonly used in the third edition, POP3 for short. Through the POP protocol, after the client logs on to the server, it can delete its own emails, or download it to the local device. After the download, the email client software can modify and delete emails locally. The IMAP protocol is also used to receive emails,

, which can generate pie charts, line charts, and column charts. You only need to add them to a third-party class library according to the instructions and import them into the class library. Take thinkphp2.1 as an example: First extract the jpgraph.zip plug-in the attachment, copy it to the thinkphp/vendor directory, and then copy the driver file "chart. class. copy "php" to 'thinkphp/lib/think/util '. Under this directory, you can directly use it in the action file. Version 3.1.2 can be placed

because we can buy the desired images cheaply (to drill down the old Midea ). First, we will analyze the price list for purchasing images, which is divided into four parts: $750 (required programming shooting cost) + $250 (L1 level image) + $5 (processing cost) + $20 (DVD, you can select ftp mode to save) Once our order is submitted and confirmed, we will need $750 to pay for the program shooting of the tr

Then I enter the root user and designate three users, idc, c, and mu, as idc, c, and mu, the administrators of the three user groups then enter the idc user and execute the following command: [Idc @ localhost home] $ gpasswd-a mu idc Adding User "mu" to "idc" group [Idc @ localhost home] $ ls C idc linuxidc mu muchuanqi [Idc @ localhost home] $ chmod

all resources are loaded to execute this JS.After you execute this JS, you will html add a data-dpr property, as well as a style, to the (that is, document.documentelement) font-size .After that, the elements in the page can be set in rem units. htmlis the font-size base pixel of REM.convert px in visual artwork to REMFirst, the current size of the visual manuscript is divided into 640 , 750 and, 1125 these three kinds.The current scheme will divide

view constraint to 750.We then add a constraint to the yellow graph to its right relative to the parent view (as mentioned above), and the priority is 750.Drag the Restraints out!To change the right side of the blueprint at run time we have to drag this constraint into the code first. You can also drag arbitrary constraints like this. (Just like the control is associated with the code, check the constraint

of efforts, the black chain was deleted and the vulnerability of the problem was fixed, later, according to the related information security classified protection measures, basic reinforcement measures were taken for the relevant server operating system. the specific measures are as follows: 1. disable cd-rom startup with Bios password 2. ssh security-prohibit root login # Vi/etc/ssh/sshd_config # Change the protocol to 2 # PermitRootLogin no prohibit Root users from logging on to ssh 3. disab

can always according to the root element of the font size to change its own values. The screen size of various common mobile phones is as follows:　　We want to achieve mobile phone-side adaptation, that is, you can make the page element font, spacing, width and high attribute values can vary with the size of the mobile phone screen changes, next we see how to use JS to dynamically set up REM and mobile-based adaptive, JS code is as follows:Gets the HTML element var html = document.getelementsbyt

dependent on the parent element calculation. As a matter of fact, you may have understood the use of REM, but have not yet learned how to use REM to achieve adaptive mobility. In the final analysis, the REM adaptive Mobile is the original feature of its own, it can always according to the root element of the font size to change its own values. The screen size of various common mobile phones is as follows: 　　 We want to achieve mobile phone-side adaptation, that is, you can make the pag

issues with mobile-side layouts Nowadays mobile devices are diverse, screen sizes vary, and here are a few mobile-side layouts today.1. Width percent layout + px layout.First of all, this layout although I do not use now, but still have seen, this layout if you follow the 750 design plan to do in fact, in the mainstream mobile phone screen display is very good, but if the screen is not mainstream, it shows the effect is very poor, so this layout is n

testing the compatibility of the version, determine which version number is supported for the library version used by the applet.So the screen-size compatibility test should not be tested? The applet defines a new dimension unit RPX (responsive pixel), in fact RPX is the system-level REM (divide the page 750 parts proportionally, 1rpx=window.innerwidth/750). or scale scaling layout of the width=
