We can select groups of elements by separating their selectors with commas.

<html><head><style>div, .trailer, #listItem1 {border: 2px solid #44accf;}</style></head><body><div>I'm in</div><p class="trailer">Me too</p><ul><li id="listItem1">Same here</li><li>I'm not</li></ul></body></html>
]]>

Nice! This way, the same declaration block applies to all three selectors.

Wait, is that list item really a class?
