In order to create a horizontal line with a breakdown in the middle that displays an arrow, I want to use only HTML and CSS without relying on bitmap images. If needed, Font Awesome can be used to achieve the desired result. It's important for me to have control over the line's thickness and color, while the exact angle of the breakdown doesn't matter. Although I am familiar with the CSS triangle trick, I'm unsure how to apply it effectively in this specific scenario.
