Yes this can be done in 2 steps.
First, “comment out” or remove the responsive code in your functions file which looks like this –
/** Add Viewport meta tag for mobile browsers */
add_action( 'genesis_meta', 'tachmorn_viewport_meta_tag' );
function tachmorn_viewport_meta_tag() {
echo '<meta name="viewport" content="width=device-width, initial-scale=1.0"/>';
}
Second, you would need to comment out or remove the responsive code at the bottom of your style.css file. Everything under this – /* Responsive Design
------------------------------------------------------------ */
It would probably be better to just comment it out if you plan to use it in the future. To comment something out add this – /* at the beginning of the code and this – */ at the very end.
