represented by 4 physical pixels. The 1px border of the retina screen,In fact, the original intention of the designer is 1 physical pixels. It is conceivable that for programmers, the CSS should be implemented in the 0.5 CSS pixel border, which is why the designer always feel that the dpr=2 screen 1px line is very thick.Bit image is the concept used when working with high-definition images. When 1 physical pixels can represent a 1-bit image, the picture is clear. What we usually call X2 times i

What is REM In my opinion, REM is the pixel value of the HTML node fontsize, which is the 1rem unit. So changing the fontsize of HTML nodes is the most critical step. Depending on the width of the phone to change the relative size can be achieved by adaptation, there is no need for any media to query those. Our designs are often 640 or more wide, but I suggest using this size to 640 as the benchmark, to s

Learn more about the EM,REM,PXpx pixels, relative length units. Pixel px is relative to the display screen resolution, in the Web page, we use PX to set the text, PX is more stable and accurate, but this method has a problem, when the user in the browser to browse our web page, it changed the browser font size, This will be broken using our web page layout. You can then use EM to define the font for the Web page.EM is also a relative length unit, rela

There is a big drawback is that the UI gives the design of the width is certain, in the response to the feeling is a super uncomfortable aesthetic tangle. 2. Percent: Percent is also quite troublesome, but also to go to various calculations, not the programmer should do cumbersome things.
