I am using the code above to change my white logo to black for light colored pages. I am currently targeting a specific page (matthewbridgham.com/blog) as a test and it seems to be working everywhere but firefox. I have searched far and wide for a solution and nothing works. Please help me.

To change logo to black, add this to Design > Custom CSS

/* Blog logo */
body[class*="type-blog"] .header-title-logo img {
    filter: invert(1);
    -webkit-filter: invert(1);
}

 

Amazing work! Thanks!
