The solution to the compatibility problem of css browser

1. Using cssHack to solve compatibility issues

Browsers may encounter unrecognized code when reading css code, and there are usually two reasons for this:

1. There is something wrong with the code itself, such as: bg:red,bg is not a valid css attribute

two。 The code is fine, but the kernel of the browser cannot recognize it, such as box-sizing:border-box. There is no problem with this code itself, but because it uses the attribute box-sizing of css3, it will not be recognized in some browsers with lower versions of the kernel.

In short, what does a browser do when it encounters unrecognized code? Unlike back-end languages such as java and C #, the browser does not abort the execution of the program, but immediately skips the unrecognized code and continues to execute the rest of the code as if it were not seen. Just like the following example:

.main {

The color1:red;/* code cannot be recognized by the browser, so the browser will assume that the code does not exist * /

Color:green

}
