1.  Read `timetable.php`, `coachs-site.php`, and `admin.php` to identify the common HTML structure and CSS classes used for the timetable.
2.  Read `style.css` to understand the existing styles applied to the timetable.
3.  Modify `style.css` to make the timetable responsive. I will add styles to make the timetable container fill the screen width on mobile and ensure it fits within its parent element on desktop, preventing horizontal scrollbars on the page level.
4.  Read `script.js` to understand its existing structure.
5.  Append JavaScript code to `script.js`. This code will dynamically reduce the font size of the timetable on desktop if it overflows its container, ensuring it fits without a scrollbar. This script will trigger on page load and on window resize.
6.  Confirm that `style.css` and `script.js` are included in `timetable.php`, `coachs-site.php`, and `admin.php`. If they are not, I will add the necessary include statements.
EXECUTER NOTE: Modified style.css to make the timetable responsive. Updated .timetable-container and #timetable styles, and adjusted media queries for mobile responsiveness.
