Bootstrap 5 Form Groups: Tips for Grouping Controls and Aligning Labels

Bootstrap 5 form groups are a core tool for organizing form elements in web development. They wrap related controls using the `.form-group` class to achieve style consistency and layout management. Basic usage requires combining with `.form-label` (label styling), `.form-control` (input styling), and spacing classes (such as `mb-3`). There are three label alignment methods: horizontal arrangement (implemented with `.row` + `.col-*` to place labels and input fields in the same row), floating labels (`.form-floating`, where the label automatically floats when the input is focused), and vertical arrangement (default, with labels on top, suitable for short forms). When grouping controls, use `.form-check` for radio/multi-select buttons and `.form-select` for dropdown menus. By skillfully applying these techniques, you can build beautiful and user-friendly forms, enhancing the user experience. It is recommended to choose the alignment method according to the scenario and master the Bootstrap 5 form system proficiently.
