Have a box flow around and highlight currently selected sections
Install with component:
component install rangermauve/highlight
Quick example:
var highlight = require("highlight");
var my_element = document.getElementById("some_section");
// Dim everything but your element
highlight(my_element);
setTimeout(function(){
// Stop highlighting
highlight();
},2000);
Also, check out test.html for a nicer example (make sure to build the component first)
