This is the question:
First, define a variable $x and set it to 1. Next, use the @while directive to create the grid system while$x is less than 13. After setting the CSS rule for width, $x is incremented by 1 to avoid an infinite loop.
Use @while to create a series of classes with different font-sizes.
There should be 5 different classes from text-1 to text-5. Then set font-size to 15px multiplied by the current index number. Make sure to avoid an infinite loop!
