is often seen in everyday development, and in order to solve the naming problem fundamentally, we need to give the attribute or method a unique name so that the problem of attribute name conflict can be prevented fundamentally.This is what ES6 designed a symbol for: resolving the object's property name conflict . Now that we know what symbol is designed for, that's what it does. Next, let's look at what it's used for:1 //define a symbol type of variable 2let

line: 6 and 6 are large. Because only this style is available, they are equally divided into two parts.
Now, when the page screen is smaller than a certain degree, you can re-select the style class for each element. Currently, col-xs-* is selected for the first two. rows -*.
Therefore:
The first line: the two elements are divided into 12 and 6, while the first line is 12, so the second element will wrap and occupy half of the six parts.
Row 2: 3 in 6 portions. A row contains 12 copies. Therefo
