Quiz CSS

Hi,
I+m just doing the quiz and there´s a text in html, that says ‘I´m red and in a square’ and that´s the way it should be, so I used class=“square” style=‘colore: red;’ and it is in a square and red.
But that´s not the solution, is there a .css style which renders the text into a square without using class?
Thx

Got it, class=“square red” did it .
