Dip:device independent pixels (device independent pixels). Different devices have different display effects, this is related to the device hardware, generally we support WVGA, HVGA and QVGA recommend this, do not rely on pixels.Px:pixels (pixels).

The font units in CSS are mainly px, EM, and Rem. where PX is a pixel, it is a font length that is relative to the display's heading resolution. In general, the default font size in the browser is 16px. Where EM is relative to the font. The value of EM is not fixed and its font size is relative to the size of the parent element's font. While REM is also a relative font, its size is not relative to the paren

I. First introduce the PXPX is the most basic length of the CSS, the unit with PX do not have any problems, you can make the page according to the precise presentation of the routine!But it is! But, but! If the entire use of PX layout will hide an egg pain problem, that is, when the user and Ctrl roll the page (white is ctrl+,ctrl-), you will find the page structure produced unpredictable confusion, so there are bricks advocate using em instead of px

Size Units (px, dpi, dp, dip, and sp) of the View for android Application Development, and androiddpi I. pixel (px) and screen resolution 1) px (Pixels, Pixels): corresponds to the actual Pixels on the screen. For example, 320*480 screens have 320 pixels horizontally and 480 pixels vertically. 2) the screen resolution is the total number of physical pixels displayed on the screen. It is equal to the number of pixels x height on the screen width. In th

Units in Delphi applications, or program modules, are well-developed. In fact, a unit is the basis of program modularization, and a class is available only after it. In a Delphi application, each form has a corresponding unit. Use the corresponding tool button or File> New Form menu command to add a New Form to the project. In fact, a New unit is added, that is, the class of the New Form is created. Unit Although all forms are defined in cells, the op

For the use of rem units, calc () for Adaptive LayoutUnit in css We all know that units in css generally include px, %, em, and other units. In addition, css3 adds a new unit rem. Px, %, and other units are frequently used in traditional la S, and you are familiar with them. However, px

More accurately, the interface elements are scaled to the size of the browser font.Users can adjust the browser font size according to their needs, for example, some people have poor eyesight, may need to change the browser's default font size.At this point, we want the width of the page element, margin, padding and other dimension elements will be scaled accor

This paper introduces the key length, clear text length and ciphertext length that must be taken into account in RSA plus decryption, and for the first time developers of RSA, RSA is a more complicated algorithm, and the complexity of RSA is because mathematicians take efficiency and security into account.In this paper, we talk about the concept of key

If you are a front-end development engineer, the average PX and EM usage frequency is higher. But today the focus of this article is to introduce some of the units we use very little or even heard of.First, relive EMBecause Font-size is inherited, the darker the number of layers, the larger the font.Second, REMAlthough the use of EM above may be used in development, but we sometimes want to have a benchmark to expand. When this requirement is met, we

Here is an explanation of the difference between the CSS font units and the implementation of the font response style. The content is very good, now share to everyone, but also for everyone to make a reference. Problem Scenario: How can I set the font size in different window sizes and the readability of different mobile devices during the implementation of responsive layouts? What you need to know is: Conversion relationship between 1.PX,EM,PT1em =
