--description--

La diferencia clave entre tr[class="total"] y tr.total es que el primero seleccionara los elementos tr donde la única clase sea total. El segundo seleccionará los elementos tr donde la clase incluya total.

En tu caso, tr.total funcionará. Puedes usar este selector para apuntar a todos los elementos td dentro de tus filas .total. Alinea el texto a la derecha, y dales un relleno de 0 0.25rem.

--hints--

Debes tener un selector tr.total td.

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

Tu selector tr.total td debe tener una propiedad text-align establecida en right.

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

Tu selector tr.total td debe tener una propiedad padding establecida en 0 0.25rem.

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