Column Styles

Next, you’ll format the grid columns. Go to the Column Styles section. Create a style rule to float all div elements whose class value starts with “col-” on the left margin. Set the padding around all such elements to 2%. Finally, apply the Border Box Sizing model to the content of those elements.
(Note: Remember to use web extensions to provide support for older browsers.)

In the same section, create style rules for div elements with class names .col-1-1, .col-1-2, .col-1-3, .col-2-3, .col-1-4, and .col-3-4 to set their widths to 100%, 50%, 33.33%, 66.67%, 25%, and 75% respectively.

Here is my code:

div[class^="col-"]{

float:left;

padding: 2%;

-webkit-box-sizing: border-box;

-moz-box-sizing: border-box;

box-sizing: border-box;

}

div.col-1-1 {width: 100%;}

div.col-1-2 {width: 50%;}

div.col-1-3 {width: 33.33%;}

div.col-2-3 {width: 66.67%;}

div.col-1-4 {width: 25%;}

div.col-3-4 {width: 75%;}

And this is the error I am getting:

Simulation Output73.15625px Traceback (most recent call last): File "nt-test-9c78cce5.py", line 10, in <module> assert('133.' in elm.value_of_css_property('width')) AssertionError

I am not sure what this error means and why I am getting it. Any help would be appreciated. Thanks.
