Lack of constistency in borders

[mrreus]

Every category in website have different style of borders, for example:

• Docs has square borders (by the way weird borders...) in a different color than other categories,
• Home has square borders (especially in the Updates & Features section),
• Forum has borders in a different color than other categories,
• etc.

Additionally:

• Tables in Docs should have borders for better readability,
• Docs and Servers have different styles of box inputs.
