I am having trouble completing the challenge for the "Create and Edit Lightning Components" module of the "Lightning Components Basics" trail. Here is the challenge:Create a camping component that contains a campingHeader and a campingList component. The campingList component contains an ordered list of camping supplies that include Bug Spray, Bear Repellant, and Goat Food. The campingHeader component contains an H1 heading style with a font size of 18 points and displays 'Camping List'.Here is my code:camping.cmp<aura:component > <c:campingHeader/> <c:campingList/></aura:component>campingHeader.cmp<aura:component > <H1>Camping List</H1></aura:component>campingHeader.css.THIS {}H1.THIS { font-size: 18px;}campingList.cmp<aura:component > <aura:attribute name="campingSupplies" type="List" default="['Bear Repellant', 'Bug Spray', 'Goat Food']" /></aura:component>When I check the challenge, I get the error message:Challenge Not yet complete... here's what's wrong:The component is not using the correct font size.Any help is greatly appreciated.
