This lesson

This lesson teaches Form layout—the ideas, syntax, and habits you need before moving on in Bootstrap.

Forms are where users convert and where security mistakes (validation, labels) show up first.

You will apply Form layout in contexts like: Internal tools, WordPress themes, Laravel apps, and teams that want opinionated UI without writing every rule from scratch.

Read the lesson, edit HTML/CSS in the playground, press Run to preview, then answer the lesson MCQs.

Toward the end of the track—use it to consolidate patterns before the capstone or summary lessons.

Vertical stacks with mb-3 wrappers are the default and work well on mobile. For wider screens, combine the grid: put labels and fields in row + col-* columns, or use horizontal layouts with col-form-label aligned to control columns.

Floating labels

form-floating wraps an input and label so the label animates above the field when focused or filled. Place the label after the input in markup. Floating labels save vertical space in dense admin forms—use placeholders that remain readable when empty.

Inline and grouped rows

row g-3 with col-md-6 splits related fields (city/state) on medium breakpoints. Compare with utility-first form spacing in Tailwind forms where you compose gaps manually.

Self-check

When would you pick floating labels over standard labels?
Which grid classes align a label and input on one row at md?
Why keep related fields in the same row?
