I choose Open Sans as my font for my site (as of writing this post). Now that I’ve created a child theme, I want to change the font. To do this, we will be working with our style.css and functions.php files within our child theme folder.

Update functions.php

function google_fonts() {
 $query_args = array(
 'family' => 'Open+Sans',
 'subset' => 'latin,latin-ext',
 );
 wp_register_style( 'google_fonts', add_query_arg( $query_args, "//fonts.googleapis.com/css" ), array(), null );
 }
add_action('wp_enqueue_scripts', 'google_fonts');

Update style.css

/* google font */
ul li {
 font-family: open Sans, sans-serif;
}

p {
 margin: 0 0 20px;
 font-family: open Sans, sans-serif;
}

h1,
h2,
h3,
h4,
h5,
h6 {
 font-family: open sans, sans-serif;
}
