Issue number: internal
What is the current behavior?
Developers are unable to globally change the placeholder opacity for inputs, textareas, searchbars, and selects. This becomes particularly problematic when trying to apply a high contrast theme.
What is the new behavior?
--ion-placeholder-opacity
with a fallback of0.6
(this fallback is unchanged)--ion-placeholder-opacity
to0.8
for the high contrast light & dark themesNote
The ticket says to update the standard light and dark themes to define
--ion-placeholder-opacity: 0.6
, however, I did not do this because this is not different than the fallback and therefore does not need to be defined.Does this introduce a breaking change?
