Moodle 3.0.3 Essential 3.0.1
The text and background box are both black in a search box that appears when going to the grading form search: Course>Assignment>Advanced Grading>Select grading method dropdown and choose Marking guide or Rubric> click Create new grading form from template. This brings me to /grade/grading/pick.php
Ideally the black text will be white. Also the blue search text field is easily mistaken for a button. I think it should white, like most text fields. The black box is responsive but in this instance seems a bit bulky in some sizes. Other pages the black box is slim. Maybe because it usually just has buttons, not a checkbox, text, search window (empty text field) and a Search button.
