Hello,
I used the full name of the div but it didn't work. Why did we used only "col" here. Normally we call all the class name.
.primary col, .secondary col { display: inline-block; width: 50%; margin-right: -4px; vertical-align: top; padding-left: 1em; padding-right: 1em; }

Move on to the next next video and see how the instructor used the class names separately in the CSS rules to get the desired effect.

231,248 PointsYou're quite right. A space creates a "descendant selector" where one element is inside the other.
