grid wraP CSS code example

Example 1: css grid wrap columns

Use this if you are trying to wrap your rows in css grid like with
flex-wrap.

grid-template-columns: repeat(auto-fill, <your-size>px);

Example 2: grid repeating auto columns

/* To achieve wrapping, we can use the auto-fit or auto-fill keywords. */

grid-template-columns: repeat( auto-fit, minmax(250px, 1fr) );

Example 3: css grid auto wrap

this one will provide a more responsive behavior as you can specify the
minimum size to start wrapping and max size so it grows and adapts to 
bigger screens

grid-template-columns: repeat(auto-fill, minmax(300px, 3fr));
