Manipulating images and color can either be very rewarding, or somewhat daunting, depending on how simple or complicated we make our processes! Fortunately, PostCSS can help automate a fair degree of our processes, so let's take a moment to consider what we've covered throughout this chapter.

We kicked off with a look at adding media assets, and using PostCSS to automatically update asset links, this helps remove any risk that we inadvertently use the wrong link!

We then moved on to manipulating images, we started with a look at creating image sprites, first using SASS, before transitioning to using PostCSS. Next up came a more in-depth look at altering images, where we used the Evil Icons SVG library and set up PostCSS to alter the color of each icon at compilation. We then moved on to learn about how we can switch in the WebP image format; while most people might use standard format images, we learned how easy it is to switch-in WebP images, when using a supported browser.
