Bootstrap 5 Close Button

Example

Provide an option to dismiss or close a component with .btn-close. Default styling is limited, but highly customizable. Modify the Sass variables to replace the default background-image. Be sure to include text for screen readers, as we’ve done with aria-label.

<button type="button" class="btn-close" aria-label="Close"></button>

Disabled state

Disabled close buttons change their opacity. We’ve also applied pointer-events: none and user-select: none to preventing hover and active states from triggering.

<button type="button" class="btn-close" disabled aria-label="Close"></button>

Dark variant

Add data-coreui-theme="dark" to the .btn-close, or to its parent element, to invert the close button. This uses the filter property to invert the background-image without overriding its value.

<div data-coreui-theme="dark">
  <button type="button" class="btn-close" aria-label="Close"></button>
  <button type="button" class="btn-close" disabled aria-label="Close"></button>
</div>

CoreUI vs Bootstrap

While this Close Button component is fully compatible with Bootstrap and follows its core principles, CoreUI delivers a more complete solution for modern app development.

What sets CoreUI apart from Bootstrap?

• ✅ Fully compatible with Bootstrap – Built directly on Bootstrap, all classes and behaviors work as expected.
• 🧠 Framework-native versions – CoreUI provides dedicated libraries for React.js, Vue.js, and Angular, unlike Bootstrap which relies on third-party plugins for JavaScript frameworks.
• 👨‍💻 Maintained by a full-time team – CoreUI is developed as a professional product, not a volunteer-driven project.
• 📦 More built-in components – Includes additional ready-to-use components like range sliders, multi-selects, steppers, etc.
• 🛠️ Sass Modules support today – CoreUI already supports Sass Modules, which are planned for Bootstrap 6.
• 🌍 Better LTR/RTL support – Uses modern CSS logical properties for seamless bidirectional layout support.
• 🔒 LTS (Long-Term Support) – Bootstrap now offers LTS only via paid third parties like HeroDevs, while CoreUI continues to offer long-term support natively and for free.

Whether you’re building internal tools, dasards, or SaaS platforms — CoreUI combines the familiarity of Bootstrap with a more powerful, scalable, and production-ready ecosystem.
