tailwind.config.js contains duplicate values for spacing. eg,

...
        "1/2": "50%",                       // Value for 50% spacing
        "1/3": "33.333333%",
        "2/3": "66.666667%",
        "1/4": "25%",
        "2/4": "50%",                      // Value for 50% spacing
        "3/4": "75%",
       

Describe the bug

1. The on-hover information of the programming exercise lifecycle is only partially readable.
2. The on-hover information of the Automatic Test and Assessment Type option is displayed at the top but the other popups are displayed to the bottom. This could be more consistent.

To Reproduce

1. Create a new programming exercise
2. Scroll to the timeline settings

Reproduction Steps

• HS-193247
• Create a certificate
• Open in Safari
• Print the cetificate

Expected Behavior

• The orientation and size of the certificate should made the settings in the certificate and be confined to a single page

Actual Behavior

• the orientation defaults to portrait and splits into two pages:

The most recent full CI build (at the time of this writing) failed due to connection refused, but it was just transient (manually browsed the site and confirmed it worked).
