Original: You may not notice the CSS unitThe 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%;}And then 1em = 10px

is equal to the body set of font-size.You see, the font size of this div here is 1.2em. The explanation is that he inherits the font size (here is 14px) from the body Dad 1.2 times times, the result is 16.8px.But what happens if you use EM to define the font size of nested elements in a layer of one level? In this little piece of code, we apply the same CSS as above, each of which inherits the font size from its parent, and increases gradually.InstanceAlthough this is what we want in some place

relationship here is that UTF-8 is one of the ways Unicode is implemented.One of the biggest features of UTF-8 is that it is a variable-length coding method. It can use 1~4 bytes to represent a symbol, varying the length of a byte depending on the symbol.The coding rules for UTF-8 are simple, with only two lines:1) for a single-byte symbol, the first bit of the byte is set to 0, and the next 7 bits are the

Windows (Viewport) unit Windows (Viewport) units are relative units, meaning they have no objective dimensions. Their size is determined by the size of the window (Viewport).

We often use graphics objects to draw texts during programming. However, sometimes the width of the text cannot be obtained to precisely locate the position of the text, and font can be used for the font height. it is a headache to get the width of the height attribute ...... A label control (set autosize to true) is often used to measure the length of the text, but it is always uncomfortable ....... Later, we found that: The relationship between t

just a measure of the pixel density. Third, DPIndependent of the physical density of the unit of measurement, it is based on 160dpi , regardless of the DPI screen, 1DP represents the same physical length. In the 160dpi screen, 1DP=1px, that is, a DP needs to be represented by an PX , on the 240dpi screen, 1DP=1.5px, indicating a DP needs 1.5 px to indicate. That is to say 1DP=dpi/160*px. The implication is that developers will be able to develop a UI
