Description

When you used grid-template-columns and grid-template-rows to define the structure of a grid, you entered a value for each row or column you created. Lets say you want a grid with 100 rows of the same height. It isn't very practical to insert 100 values individually. Fortunately, there's a better way - by using the repeat function to specify the number of times you want your column or row to be repeated, followed by a comma and the value you want to repeat. Here's an example that would create the 100 row grid, each row at 50px tall.
grid-template-rows: repeat(100, 50px);
You can also repeat multiple values with the repeat function and insert the function amongst other values when defining a grid structure. Here's what that looks like:
grid-template-columns: repeat(2, 1fr 50px) 20px;
This translates to:
grid-template-columns: 1fr 50px 1fr 50px 20px;
Note
1fr 50px is repeated twice followed by 20px.

Instructions

Use repeat to remove repetition from the grid-template-columns property.

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 width of <code>1fr</code>.
    testString: assert(code.match(/.container\s*?{[\s\S]*grid-template-columns\s*?:\s*?repeat\s*?\(\s*?3\s*?,\s*?1fr\s*?\)\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 width of <code>1fr</code>.');
