To write cross-browser CSS, you must know the two modes for the browser to parse CSS: standard mode and quirks mode ).
The so-called standard mode means that browsers are parsed and executed according to W3C standards.CodeThe weird mode is to use the browser's own method to parse and execute code, because different browsers do not parse and execute code in different ways, so we call it the weird mode. The
