--description--

La differenza principale tra tr[class="total"] e tr.total è che il primo seleziona gli elementi tr in cui l'attributo class ha solo il valore total. Il secondo selezionerà gli elementi tr in cui il valore dell'attributo class include total.

Nel tuo caso, tr.total funzionerà. È possibile utilizzare questo selettore per selezionare tutti gli elementi td all'interno delle righe .total. Allinea il testo a destra e assegna loro un padding di 0 0.25rem.

--hints--

Dovresti avere un selettore tr.total td.

assert(new __helpers.CSSHelp(document).getStyle('tr.total td'));

Il selettore tr.total td dovrebbe avere una proprietà text-align con il valore right.

assert(new __helpers.CSSHelp(document).getStyle('tr.total td')?.getPropertyValue('text-align') === 'right');

Il selettore tr.total td dovrebbe avere una proprietà padding con il valore 0 0.25rem.

assert(new __helpers.CSSHelp(document).getStyle('tr.total td')?.getPropertyValue('padding') === '0px 0.25rem');
