How do I remove the "Posted" item on the job listing so that it doesn't show when the job was posted.

It makes the listing look stale if the date is too old

Thanks

I just added this CSS:
div.jsjb-jm-page-content-wrap div.jsjb-jm-newestjob-jobs-list-main-wrap div.jsjb-jm-newestjob-jobs-list-wrap div.jsjb-jm-newestjob-jobs-list-top-wrap div.jsjb-jm-newestjob-jobs-list-data-left .jsjb-jm-newestjob-jobs-list-title span.jsjb-jm-newestjob-jobs-list-time {
    display:none;
}

I tried adding that to a custom css and it didn't work; where would you recommend that be placed?

Thank you

Appearence/Customize/bottom custom CSS field.
.../wp-admin/customize.php

Sorry, I am not a programmer as you; this why I buy from you.

Where is wp-admin/customize.php?

No worries mate, you are not buying anything from me, as I am a user of this product just like you. Also not a professional programmer:-)
Anyway, the first question: which version are you using? Joomla or Wordpress? My solution was for the Wordpress version. Joomla has  other way to add custom CSS code.
