The web worker is populated with Cheerio for modifying HTML. Here are a few samples of what can be done:
// Add customization attributes for StampReady $('.content-wrapper').attr('data-bgcolor', '#EEEEEE'); $('.column-module').attr('data-link-color', '#444444'); // Make an element deletable in Eloqua $('.spacer').wrap('<span elq-delete="true">');
These are only a few examples, feel free to explore the Cheerio API. It's very similar to jQuery.
