Description

There's another built-in function to use with grid-template-columns and grid-template-rows called minmax. It's used to limit the size of items when the grid container changes size. To do this you need to specify the acceptable size range for your item. Here is an example:

grid-template-columns: 100px minmax(50px, 200px);

In the code above, grid-template-columns is set to create two columns; the first is 100px wide, and the second has the minimum width of 50px and the maximum width of 200px.

Instructions

Using the minmax function, replace the 1fr in the repeat function with a column size that has the minimum width of 90px and the maximum width of 1fr, and resize the preview panel to see the effect.

Tests

tests:
  - text: <code>container</code> class should have a <code>grid-template-columns</code> property that is set to repeat 3 columns with the minimum width of <code>90px</code> and maximum width of <code>1fr</code>.
    testString: assert(code.match(/.container\s*?{[\s\S]*grid-template-columns\s*?:\s*?repeat\s*?\(\s*?3\s*?,\s*?minmax\s*?\(\s*?90px\s*?,\s*?1fr\s*?\)\s*?\)\s*?;[\s\S]*}/gi), '<code>container</code> class should have a <code>grid-template-columns</code> property that is set to repeat 3 columns with the minimum width of <code>90px</code> and maximum width of <code>1fr</code>.');
