How Can I Effectively Customize Bootstrap CSS Templates Without Compromising Future Updates?

Effective Customization Techniques for CSS Templates

As you embark on customizing Bootstrap from Twitter, it's crucial to consider the best practices for seamless modifications while preserving the template's integrity and sustainability. Let's examine your options and determine an optimal approach.

Background Image Addition Considerations

You have three potential approaches for adding background images to the top navigation:

• Modifying .topbar Classes: This method alters the .topbar classes in bootstrap.css, providing direct control but potentially affecting all .topbar elements.
• Creating New Classes: Implementing new classes with background images and applying them alongside Bootstrap styles may lead to conflicts. To mitigate this, you can separate .topbar into distinct classes and use only the ones necessary.
• Using Variables with .LESS: While using variables in .LESS seems promising, concerns arise regarding CSS compilation on the client side and code sustainability.

Recommended Customization Process

The recommended customization process involves:

1. Forking Bootstrap: Create a fork of the Twitter-Bootstrap repository on GitHub and clone it locally to maintain access to future updates.
2. Preserve Bootstrap.css: Avoid modifying the bootstrap.css file directly to simplify future upgrades.
3. Create Custom CSS: Establish your own CSS file to overwrite specific Bootstrap styles as needed. Use custom class selectors to target specific elements and override desired attributes.
