# --description--
Notice how the thickness of the line looks bigger? The default value of a property named `border-width` is `1px` for all edges of `hr` elements. By changing the background to the same color as the background, the total height of the line is `5px` (`3px` plus the top and bottom border width of `1px`).
Change the `height` property of the `hr` to be `2px`, so the total height of it becomes `4px`.
