Hi @[email protected],
For the above, you have to create a child theme. You can find more details on creating child theme HERE. Then in child theme’s functions.php add the following codes.
add_action( 'init' , 'catchresponsive_child_adjust_image_size');
function catchresponsive_child_adjust_image_size() {
remove_image_size( 'catchresponsive-square');
add_image_size( 'catchresponsive-square', 300, 197, true);
}
Then go to “Dashboard=> Appearance=> Customize=> Theme Options=> Custom CSS” box and add the following CSS:
.excerpt-image-left .has-post-thumbnail .archive-post-wrap .entry-container {
width: 60%;
}
.excerpt-image-left .has-post-thumbnail .archive-post-wrap .featured-image {
max-width: 300px;
width: 39%;
}
