--description--

You can use absolute and relative units like px and em in CSS Grid to define the size of rows and columns. You can use these as well:

fr: sets the column or row to a fraction of the available space,

auto: sets the column or row to the width or height of its content automatically,

%: adjusts the column or row to the percent width of its container.

Here's the code that generates the output in the preview:

grid-template-columns: auto 50px 10% 2fr 1fr;

This snippet creates five columns. The first column is as wide as its content, the second column is 50px, the third column is 10% of its container, and for the last two columns; the remaining space is divided into three sections, two are allocated for the fourth column, and one for the fifth.

--instructions--

Make a grid with three columns whose widths are as follows: 1fr, 100px, and 2fr.

--hints--

container class should have a grid-template-columns property that has three columns with the following widths: 1fr, 100px, and 2fr.

assert(
  code.match(
    /.container\s*?{[\s\S]*grid-template-columns\s*?:\s*?1fr\s*?100px\s*?2fr\s*?;[\s\S]*}/gi
  )
);
