8,424 PointsHow much negative margin do I need?
Here's the question for the code challenge I'm stuck on:
"It looks like the whitespace between our columns is causing the secondary column to break to the next line. Let's create a new rule that removes the whitespace with a negative margin. "
And here's my code:
/* Complete the challenge by writing CSS below */
.main-header {
padding: 5px;
}
.main-logo, .main-nav, .main-nav li, .col {
display: inline-block;
}
.col {
margin-left: -5px;
}
In the preview of the code challenge, adding this negative margin does fix the issues but I am not passing the code challenge. What is the proper way to solve this problem?

8,424 PointsI just figured it out. The code challenge question was looking for a margin-right property rather than left, and now I've passed the section. Thank you for your response!

5,568 PointsHave you tried the shorthand? margin: 0 0 0 -5px;
The way I remember what's what in shorthand is by looking at my monitor and drawing a box mentally, top, right, bottom, left.
