finally got black text to show through transparency with pointer-events: none. yay
updated top nav text and anchor
added instructor imgs, student data edits and css for small headshots
added instructor data to student data, renamed refs in main.js to student so that it's general for student and instructor profiles, deleted instructor-data file
made js profileBox objects to have same code for student and instructor profiles. clicking on a student image will update profile in top box, clicking on instructor image will update profile in bottom box. updated class and ID names in index for js purposes.
reconfigured profile boxes so that profile is above thumbnail grid. need to fix padding, spacing, margins still.
removed main.css because it was redundant
