Treehouse TeacherHey Antonio Gonzalez you'll need to use DOM Selection from this unit to select all of the list items and store them in the list item variable
Joe Mbome
Front End Web Development Techdegree Graduate 17,250 Pointshello Antonio you should try this;
var listItems=document.querySelectorAll('li'); var colors = ["#C2272D", "#F8931F", "#FFFF01", "#009245", "#0193D9", "#0C04ED", "#612F90"];
for(var i = 0; i < listItems.length; i ++) {
listItems[i].style.color = colors[i];
}

Treehouse TeacherKathryn Kassapides you are correctly selecting the elements but that variable should be named list items

Front End Web Development Techdegree Student 10,652 PointsThe for loop cycles over list items and applies a color to each item using the values stored in the colors array. For example, the first color in the array ( #C2272D) is applied to the first list item, the second color (#F8931F) to the second list item, and so on. Complete the code by setting the variable listItems to refer to a collection. The collection should contain all list items in the <ul> element with the ID of rainbow.
Here is the full question sorry it got cut off.
