--description--

Simply creating a grid element doesn't get you very far. You need to define the structure of the grid as well. To add some columns to the grid, use the grid-template-columns property on a grid container as demonstrated below:

.container {
  display: grid;
  grid-template-columns: 50px 50px;
}

This will give your grid two columns that are each 50px wide. The number of parameters given to the grid-template-columns property indicates the number of columns in the grid, and the value of each parameter indicates the width of each column.

--instructions--

Give the grid container three columns that are each 100px wide.

--hints--

container class should have a grid-template-columns property with three units of 100px.

assert(
  code.match(
    /.container\s*?{[\s\S]*grid-template-columns\s*?:\s*?100px\s*?100px\s*?100px\s*?;[\s\S]*}/gi
  )
);
