0 Core.css is a very small CSS reset and grid system. If your project is very small, you don't need to use a large css framework such as Bootstrap. You only need less than 4kb core.css, you can have css reset. And grid systems and responsive layouts.

Core.css uses a .row to represent the rows in the container. If you append a class with the largest width to it, it represents a fixed-width row, otherwise it is a full-screen row. .col represents the column in the container, which divides the width of the container into 12 columns, which is what we often call a 12-grid system. .xs-12 represents a column width of 100%. Similarly, .xs-3 represents a column width of 25% because it requires 4 .xs-3 to reach 100% of the 12 grid. Others are analogously from .xs-1 to xs-12.
