The style  hierarchy is complex in this site. I would suggest that in your CSS
sheet you put

.x126, .x127{
color:#000000;
}

However the page  is so complex that I am not sure if that is overridden by a
later style somewhere.

The borders are more complex as they are overridden by inline styles.

You could try putting in the style declaration above:
"Border 2px solid black !important;" In fact you could also use the
!important declaration for the color as well (it overrides subsequent and
higher ranking styles) so the final style declaration would be

.x126, .x127{
color:#000000 !important;
Border 2px solid black !important;
}
