# --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.

Let's 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.

```css
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:

```css
grid-template-columns: repeat(2, 1fr 50px) 20px;
```

This translates to:

```css
grid-template-columns: 1fr 50px 1fr 50px 20px;
```

**Note:** The `1fr 50px` is repeated twice followed by 20px.

# --instructions--

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

# --hints--

`container` class should have a `grid-template-columns` property that is set to repeat 3 columns with the width of `1fr`.

```js
assert(
  code.match(
    /.container\s*?{[\s\S]*grid-template-columns\s*?:\s*?repeat\s*?\(\s*?3\s*?,\s*?1fr\s*?\)\s*?;[\s\S]*}/gi
  )
);
```
