CSS magic! How to convert arbitrary CSS type to numeric value?
There are various type values in CSS, such as 1rem, 10vw, 100cqw, etc. These relative values give CSS powerful adaptability. But sometimes, we also need to know the real value corresponding to these relative values, that is, the px value. For example, on the mobile terminal, we often set the root font size like this: […]
