This challenge will expound upon the previous challenge by adding the **auto-fill** value to the *repeat* function. This will cause the number of divs to expand based on the viewport's size rather than the previously specified column value. In the **Before** section below, the **grid-template-column** value "3" is specified.
*Keep in mind that the following code snippets are only examples and not the exact challege from freeCodeCamp's curriculum.*
