This is a creation in Article, where the information may have evolved or changed. The first item in "Go Language Programming" is Calc, which, according to the author's description in the book, runs without problems under Linux. However, after practice, the program can not print out the results described in the book. After testing, it was found that the Windows command line performs calc Add 2 3 o'clock, whi

It's really quite a surprise, and it's good for percent width. We had box-sizng before, and now we have one more, and Calc is more practical. We can do some subtraction on attributes such as border, margin, pading, font-size and width, and simply take the width example:{Background-color: #dee; height: 200px; padding: 40px; display: inline-block; width: calc (100%-2 * 40px);}Notes for writing:Width:calc (100

recently, the bandwidth concept and calculation of PCIe are somewhat blurred, and most of the online search data is a mold, This is calculated by the following formula:Parallel bus bandwidth (MB/s) = parallel bus clock frequency (MHz) * Parallel bus bit width (BIT/8 = B) * Transmission of several sets of data per clock (cycle)In particular, after the calculation is not very easy to understand, and then afte

the problem that needs to be solved at present. At this time, C3 in a new length unit--VW. The description of this unit is: relative to the width of the viewport. Viewport is divided into 100 units of VW, that is, in the 375-width screen, 1vw equals 3.75px,320 screen, 1vw equals 3.2px. So for different sizes of the screen has a unified unit to measure, then we combine REM, that is, the HTML font size FONT-SIZE:CALC (100vw/18.75)-This is the size of the IPhone6 as the design of the calculation,

Let's talk about the Calc () feature. This function allows you to perform simple arithmetic calculations, such as calculating the length of the elements, and eliminates the ability to write JavaScript code that is not easy to maintain. This function supports all simple basic arithmetic operations, including subtraction. For example, you want to create an element that fills its parent element with its width, but it also leaves a portion of the pixel w
