What advanced form features exist in Bootstrap 5.3?

March 18, 2026

No strings attached, just valuable insights for your project

Bootstrap 5.3 provides advanced form features such as floating labels using .form-floating, built-in validation states (.is-valid / .is-invalid), styled range inputs, and native color pickers via <input type="color">. Select fields are implemented using the styled native .form-select element rather than JavaScript-based custom dropdowns. Server-side validation integrates by manually applying validation classes and feedback messages, enabling modern, accessible forms with minimal custom CSS.

Code Example:-

Code

<div class="row g-3">
  <!-- Floating Label -->
  <div class="col-md-6 form-floating">
    <input type="email" class="form-control is-valid" id="email" placeholder="[email protected]">
    <label for="email">Email address</label>
    <div class="valid-feedback">Looks good!</div>
  </div>

  <!-- Range Slider -->
  <div class="col-md-6">
    <label for="volume" class="form-label">Volume</label>
    <input type="range" class="form-range" id="volume" min="0" max="100" value="50">
  </div>

  <!-- Color Picker -->
  <div class="col-md-6">
    <label for="color" class="form-label">Choose color</label>
    <input type="color" class="form-control form-control-color" id="color" value="#0d6efd">
  </div>

  <!-- Custom Select Dropdown -->
  <div class="col-md-6 form-floating">
    <select class="form-select" id="priority">
      <option selected>Choose priority</option>
      <option value="1">High</option>
    </select>
    <label for="priority">Priority</label>
  </div>
</div>
