If a system has incorrectly implemented the Jobs Widget. The CSS stylesheet that is included in the code is missing from the page. You can either write your own styles or include the stylesheet included with the widget code. Unfortunately, many popular CMS systems will strip out the CSS stylesheet link when you paste the widget code in without you noticing. You will need to add the CSS stylesheet link to the page.
Below is the missing link that has been stripped from the widget code (example):
<link rel="stylesheet" type="text/css" media="all" href="//assets.applicant-tracking.com/stylesheets/embed.css" />
Customer will need to add this link to the widget code. They can look at the code under Account Details then Embeddable Jobs Widget to see where it goes.
