horizontal line
Side to side
A horizontal line runs parallel to the horizon—straight across rather than up and down.
In geometry, it has zero slope.
The term appears in mathematics, design, and everyday description: Draw a horizontal line across the page.
Horizontal lines suggest stability and calm, contrasting with the tension of vertical or diagonal ones.
