As we are looking to enhance the user experience of our Career Website, I wanted to explore what the functionalities are with using custom Javascript and custom css. There are many potential use cases for this, one example being giving candidates the ability to download a Job Description as a PDF. This particular example would depend on a dedicated javascript PDF library delivered as a CDN, using the javascript "src" attribute.
