eh eh eh!
I did it!
I changed the file
\wp-content\themes\twentythirteen\inc\custom-header.php
in the function twentythirteen_admin_header_style()
change the block
<?php
if ( ! empty( $header_image ) ) {
echo ‘background: url(‘ . esc_url( $header_image ) . ‘) no-repeat scroll top; background-size: 1600px auto;’;
} ?>
into
<?php
if ( ! empty( $header_image ) ) {
echo ‘background: url(‘ . esc_url( $header_image ) . ‘) no-repeat scroll left top; background-size: 1600px auto;’;
} ?>
(added “left” between “scroll” and “top”)
Now the background image of the header is nicely left aligned!
I cannot link the site because I am still working on my local machine, I have not yet this site on a host.
Ciao!
