Hello,

Please add this code into your custom css box:

@media (max-width:480px){
#logo img.dark {
    content: url("https://timeandglam.com/time/wp-content/uploads/2015/11/logo_90px.png");
}}

Change the content url to your need.
Let us know.

Best regards!

Hello,

The custom cs box is located in your General Options > Custom CSS Code(screenshot). It is best that you paste the code here because if you take any theme update in the future, the style.css file will be overwritten and the changes will be lost. While all content in custom css box will not.

Best regards!
