Can I use the aura:id attribute to target an element for styling?
If so, is better to use aura:id instead id?

The
idwill let you get a reference to a specific DOM element.aura:idwill let you get a reference to a Component viacomponent.find("yourAuraId"). Once you have a reference to the Aura component, you can call.getElement()or.getElements()to get the DOM that that component will render. It's probably better to go through the framework APIs and use aura:id, though both will do the job to let you manipulate the specific DOM elements.Note that you can also use the
$A.util.addClass()API to add a CSS class on a Component. There's also has, remove, and toggleClass APIs.
