var list = document.getElementsByTagName('ul')[0];
list.addEventListener('click', function(e) {
if (e.target.tagName == 'BUTTON') {
var button = document.getElementByTagName('button');
var p = button.previousElementSibling;
p.className ='highlight';
}
});
var list = document.getElementsByTagName('ul')[0];
