CSS

JavaScript

// Hunting flags in the Document
//
// Using only the built-in DOM methods
// Find the three elements that have the text "FLAG" inside them
// and move them (the element) into the div with id of #bucket
//
// Hint: You can use
//     document.getElementById
//     document.getElementsByTagName
//     document.getElementsByClassName
//     document.querySelector
//     document.querySlectorAll
// and all the parent, child and sibling selectors

// 1) get FLAG 1
var el = document.getElementsByTagName("ul");
//var el = document.querySelectorAll("ul");
console.log(el);
//console.log(el[0]);
//console.log(el[0]);
	for (i=0; i<1; i++) {
	
	}


// 2) get FLAG 2

// 3) get FLAG 3

// bonus: write a function to crawl the entire document and search for the "FLAG" text, and do the job for you.
