Hello,

1-Yes, the header button does not open in new tab. To make it you need to edit theme files. Go to file …
Find this block:
<a href="<?php echo esc_url($link) ?>" class="<?php echo esc_attr( codeless_button_classes() ) ?> cl_header_button <?php echo esc_attr( $this->generateClasses( '.cl_header_button' ) ) ?>"><span><?php echo cl_remove_empty_p( cl_remove_wpautop($btn_title, true) ) ?></span></a>

and replace with this:

<a href="<?php echo esc_url($link) ?>" target="_blank" class="<?php echo esc_attr( codeless_button_classes() ) ?> cl_header_button <?php echo esc_attr( $this->generateClasses( '.cl_header_button' ) ) ?>"><span><?php echo cl_remove_empty_p( cl_remove_wpautop($btn_title, true) ) ?></span></a>

2. I don’t see any issue with the highlighted sections apart from the line height of the title. For it i added this css in your Custom Css box:

@media(max-width:480){
h2#cl_custom_heading {
	line-height:50 !important;
		}
}

Please refresh page and check again.

3. The image is set as background of the row. To replace it go to Row Settings > Design > Background Image. See screenshot: https://ibb.co/52f298x

Best regards!

Hello,

1-I am so sorry, i must have thought i pasted the file path before sending. The file is: picante\includes\codeless_builder\header-elements\cl_header_button.php

2-4-Yes, sure. Just add this css (remove the last css i gave you):

@media (max-width:480px) {
h2 {
   line-height:1.3 !important;
}
.wp-block-column {
    margin-bottom: -2em !important;
}}

Best regards!
