You can flip an image on the horizontal axis using CSS. The primary method for achieving this is by using the transform property with the scaleX transformation. Here's how you can do it:

CSS Method: Using transform: scaleX(-1)

To flip an image horizontally, you'll apply a negative scale value to the x-axis:

1. Using SVG

SVGs offer a flexible way to create shapes without relying on CSS borders. You can use an inline SVG to render a down chevron. This method is scalable and maintains sharpness regardless of size.

<div id="section">
  <svg height="36" width="36">
    <polygon points="18,36 0,0 36,0" fill="red" />
  </svg>
</div>

2. Using CSS Clip Path

The clip-path property allows you to create complex shapes without additional markup. You can create a down chevron using CSS shapes.

The ::after pseudo-element allows you to create decorative elements or shapes that can be positioned relative to the element they are applied to. In the case of creating a down chevron shape using borders, it works through the use of CSS borders to create triangles. 

Here’s a breakdown of how your example works:
