I'm trying to change the .png files for the social icons in the header. I'm using a child theme, created an image directory for it, and added the new .pngs to the directory, but when I change the image url in the css, the icon disappears entirely even though the hyperlink is active.
How do I get the child theme to recognize and display the new social icon image?
