Description

The Problem

1. Location of Issue:

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Equality_comparisons_and_sameness#comparing_equality_methods

2. Describe the Issue:

In the "Comparing Equality Methods" section, when scrolling the comparison table, it can be easy to forget what each column is supposed to represent as you'd have to scroll back to the start of the table every time to check(the table head and memorize the column names before scrolling back to where you were) because the table is quite lengthy.

3. Link to Visual/Recording Evidence (For UX):

Research direction

Start with the Comparing Equality Methods section on the linked MDN page and trace how its table is rendered in the Fred frontend. Check the existing table styles and responsive behavior before making the header remain visible while scrolling, then verify the table in Chrome at the referenced page and confirm the column labels stay readable.
