Move scripts to the bottom of the page.

This avoids two problems: the blank white screen and delayed downloads.

• Example 1 - Scripts in the Middle
• Example 2 - Scripts Top vs. Bottom
• Example 3 - Scripts at the Top
• Example 4 - Scripts at the Bottom
• Example 5 - Scripts Block Downloads
• Example 6 - Deferred Scripts
