Ok perfect
! I found it and can now switch the template to the one I customized.
I deleted the error warnings I posted above in the template.CSS. But I still get the red warning, if I enter a wrong answer. I also found this section and deleted it.
/* Tips / Validation Messages */
/* If the question is invalid, but has not been submitted, give it a pleasant warning color */
div.em_num_answers.good {
color: green;
}
/* If it is still invalid after submit, flag it in red */
.input-error div.error {
color: red;
display: block;
}
However, I still get the red underlining if a wrong answer is tryped in. Any ideas?
