Hello there! Thanks for reading. As title suggests, I am using Navigation Pro theme for blog URL https://pharmagxp.com/.
I am using default gutenberg atomic blocks plugin to create the articles in back end. The background color and text color are very irritating to eyes as I get hard to read and write. For that, I want to use plain white background color and plain black text color. I tried to change the file named appearance.php but it didn't change. Can anyone help me in this regards?
