Okay, let's dive deep into how to mark form errors using Bootstrap, creating visually appealing and user-friendly feedback for your forms. I'll break down the process with detailed explanations, code examples, and best practices.
**Understanding the Goal**
Our aim is to provide clear and immediate feedback to users when they enter invalid data into a form. We want to highlight the specific fields with errors and display informative messages explaining what needs to be corrected. Bootstrap provides excellent tools for achieving this visually.

4. **Server-Side Validation (Optional, but Recommended for Production):** While client-side validation improves the user experience, it's *not* a replacement for server-side validation. You *must* also validate data on the server for security reasons. Client-side validation can be bypassed.
