css - check if parent is ltr or rtl

css - check if parent is ltr or rtl

is it possible to check if parent's css is ltr or rtl and then apply
different styles to child element?
for example I have:
<div class="parent ltr"><div class="child"></div></div>
and
<div class="parent rtl"><div class="child"></div></div>
I would like to set different style to child class based in parent div's
ltr or rtl.
