This article will explain in detail what the implementation principle of bootstrap is. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

The implementation principle of the grid system is to define the container size, divide it equally into 12 parts (also divided into 24 or 32 parts, but 12 parts is the most common), then adjust the internal and external margins, and finally combined with media query, a powerful responsive grid system is made. The grid system in the Bootstrap framework divides the container into 12 parts.

The realization principle of bootstrap

By defining the size of the container, it is divided equally into 12 parts (24, 23, and 12 is a dozen, indicating advanced perfection), then adjust the inner and outer margins, and finally combined with media query, a powerful responsive grid system is made. The value of 12 can be modified by recompiling the LESS source.

1. The data row (.row) must be included in the container (.container) to give it the appropriate way and padding.

two。 You can add columns (. Column) to a row (. Row), but the sum of the columns cannot exceed the total number of columns divided equally, for example: 12.

3. Create the spacing between columns by setting the inner margin (padding). The effect of the inner distance (padding) is then offset by setting a negative outer distance (margin) for the first and last columns.
