Emily Venturino 2 minutes ago when you use document.querySelector() it looks at your script and finds any results matching the parameter you pass to the ().

for example, the following line will look through your script and bring back the text of an element with the ID named "example" : document.querySelector("#example")

you can then use what you have selected and manipulate it. For example, the following line would search for any element with the ID of "example", and give it a red border. document.querySelector("#example").style.border = "10px solid red";

hope that helps!
