I am having trouble understanding what the problem is.
The question asks;
Change the margin property to include 1em on the top and bottom, and set the width as described above.
And I have this as an answer:
margin: 1em 0 1em 0;
This is incorrect and I’m not sure how to correct it. Any help here would be much appreciated.
yes, that is how shorthand property is defined. if you give it one value then it hwill be applied to all top, right, bottom and left, and if you give it two values then first will be for top and bottom and second will be for left and right. Otherwise you must give four values for top right bottom left in that order
