@pennsavage: We cannot delete just on from custom css box. But we can hide whole text Posted on by add in the following css in “Appearance => Theme Options => Custom CSS” box.
.entry-header .entry-meta span:first-child { display: none; }
The only way to delete just on and date will be by building child theme. If you build child theme then you can remove the above css and the css you have added.
1. Create functions.php file in your child theme and then copy function catchevolution_posted_on from catchevolution-functions.php file to your child theme functions.php file and edit it. So, the code in your child theme functions.php file will be as following
<?php
/**
* Prints HTML with meta information for the current post-date/time and author.
* Create your own catchevolution_posted_on to override in a child theme
*
* @since Catch Evolution 1.0
*/
function catchevolution_posted_on() {
printf( __( '<span class="sep">Posted </span><span class="by-author"> <span class="sep"> by </span> <span class="author vcard"><a class="url fn n" href="%5$s" title="%6$s" rel="author">%7$s</a></span></span>', 'catchevolution' ),
esc_url( get_permalink() ),
esc_attr( get_the_time() ),
esc_attr( get_the_date( 'c' ) ),
esc_html( get_the_date() ),
esc_url( get_author_posts_url( get_the_author_meta( 'ID' ) ) ),
esc_attr( sprintf( __( 'View all posts by %s', 'catchevolution' ), get_the_author() ) ),
get_the_author()
);
}
2. Create child theme style.css as https://gist.github.com/catchthemes/11313660#file-style-css
