🧾 Bootstrap 5 – Forms Overview

Forms begin with a <form> tag, using .form-control to style individual inputs. Add spacing with .mb-*, adjust alignment with flex/grid, and ensure accessibility using aria-* attributes and label elements.

🔤 Bootstrap 5 – Form Control Types

Bootstrap supports various HTML5 input types:

• .form-control for text, email, password, number
• <textarea> for multi-line input
• .form-control with type="file" for file uploads
• Add placeholders and helper text for better UX

Example:

<input type="email" class="form-control" placeholder="Enter your email">

🔗 Bootstrap 5 – Input Groups

Input groups allow combining text fields with buttons or add-ons.

Example:

<div class="input-group">
  <span class="input-group-text">@</span>
  <input type="text" class="form-control" placeholder="Username">
</div>

📋 Bootstrap 5 – Select Menus

Create dropdown menus using:

<select class="form-select">
  <option selected>Select a country</option>
  <option value="1">India</option>
</select>

You can also create multiple selects and disable options.

☑️ Bootstrap 5 – Checks & Radios

Use .form-check for grouped toggles:

<div class="form-check">
  <input class="form-check-input" type="checkbox" value="" id="check1">
  <label class="form-check-label" for="check1">Subscribe</label>
</div>

🎚️ Bootstrap 5 – Range Inputs

Use .form-range to create sliders:

<input type="range" class="form-range" min="0" max="100">

Customize ranges with tooltips or dynamic feedback using JS.

🧷 Bootstrap 5 – Floating Labels

Floating labels provide cleaner UI:

<div class="form-floating">
  <input type="email" class="form-control" id="emailInput" placeholder="name@example.com">
  <label for="emailInput">Email address</label>
</div>

✅ Bootstrap 5 – Form Validation

Apply validation feedback using:

• .is-valid, .is-invalid for styling
• .valid-feedback, .invalid-feedback for helper text

Example:

<input type="text" class="form-control is-invalid">
<div class="invalid-feedback">This field is required.</div>

🧱 Bootstrap 5 – Form Layout Utilities

Use:

• .row and .col-* for grid-based forms
• .d-flex, .align-items-center for horizontal alignment
• .form-inline (limited use) for compact layouts

Example:

<div class="row mb-3">
  <div class="col">
    <input type="text" class="form-control" placeholder="First name">
  </div>
  <div class="col">
    <input type="text" class="form-control" placeholder="Last name">
  </div>
</div>
