#### Explanation
- Use the `:before` and `:after` pseudo-elements to create two triangles.
- The color of the `:before` triangle should be the same as the container's border color.
- The color of the `:after` triangle should be the same as the container background color.
- The border width of the `:before` triangle should be `1px` wider than the `:after` triangle, in order to act as the border.
- The `:after` triangle should be `1px` to the right of the `:before` triangle to allow for its left border to be shown.
