Bootstrap Best Practices

General

• Only style what you need. Create classes or IDs to allow targeting of specific elements.

Containers

• Use container to create padding and margins that center based on screen width.
• Use container-fluid to allow for expansion to the whole screen width while keeping a natural padding.
