units of length

We are easily unable to get rid of the use of our familiar CSS technology, when new problems arise, this will put us in a disadvantageous position.As the web continues to evolve, the need for new solutions will continue to grow. So, as Web designers and front-end developers, we have no choice but to get to know our toolset and be familiar with it.This means that we also need to understand some special tools-those that are not used very often, but when they are needed, they are the right tools.To

CSS: seven units you may not know As we all know, when CSS technology is used, it is often stuck by some strange problems. But when we face new problems, this will make us very unfavorable. However, with the development of Web, new solutions are gradually maturing. Therefore, as a Web design and front-end developer, we have no choice but to understand and use the tools or attributes we use. This also means that for those special tools or attributes,

Originating From: http://www.cnblogs.com/dolphinX/p/4097693.htmlThe ChaseThe units in CSS we often use,,, px pt em 百分比 , px and PT do not have to say moreEmEM is the relative unit, the reference is the parent element font-size , has the inheritance characteristicIf the font size is 16px (the browser's default value), then1em = 16pxThe use of conversion is very complex, especially with PX corresponding, we summed up the experienceBody {font-size:62.5%;

Use an array to save the intermediate variable. After modification, write the variable again. # Include "stdafx. H"# Include // Write a program that makes a virtual get system. // Write a program that saves and alters student records saved to and from a file.// A student shoshould consist of a first name, last name, age, GPA (double), and units completed (INT ).// Write a program that evaluates Student Information Based on teacher input (of grades an

If you are a front-end development engineer, General PX and EM use frequency is relatively high. But today the focus of this article is to introduce some of the units we use very little or even have heard. One, relive em TEST-01 (12px * 1.5 = 18px)TEST-02 (18px * 1.5 = 27PX)TEST-03 (27PX * 1.5 = 41px) Because Font-size is inherited, the darker the number of layers is, the larger the font. Second, REM Although the above use of EM may be used in de

routes. A product line is not enough, in other areas to create a new "millet phone" type of legend, slowly looking for a new market breakthrough, even at this point to push the supply chain, using their dominant position to mandatory compression costs.But is it easy to make a copy of a "Xiaomi phone" again? Millet In addition to mobile phones, other products have been in a tepid state, little wool. And the reason is that these products are not the market to reach the point of explosion, coupled

1.dp=dip2.PX is based on pixels, and the latter is based on pixel density.3.PX can be used for width height or font, DP for width, SP for fontThe 320*480 screen is the benchmark in 4.android. The same values of PX and DP, the same on the 320*480 screen, but different after changing the screen,The PX is also the same size as the 320*480, and the DP automatically fits the screen according to the scale5. Similarly, SP and DP can also be automatically adapted.-----"in development, width and height w

To randomly extract one or more unit methods from an array, we use Array_rand (), which is useful when you want to remove one or more random cells from an array. It accepts input as an input array and an optional parameter num_req, indicating how many units you want to take out-if not specified, the default is 1. If you only remove one, Array_rand () returns the key name of a random cell, otherwise it returns an array containing the random key name.

break down a string as required, enter two numbers M , N , M represents the input M string strings, N represents the number of bits per string of output, not enough to fill 0 . For example:Input: 2 8 ABC 123456789,Output: abc0000012345678,90000000#include Test results, may not be thoughtful, welcome to check the leak:Huawei machine Test-the string m is converted into a segment in n units
