Bootstrap 5 Alpha: A New Era of Frontend Development
The Bootstrap team has taken a significant leap forward with the release of Bootstrap 5 alpha, packed with exciting features that are set to revolutionize frontend development. This major update brings about a slew of improvements, including the removal of jQuery and Internet Explorer support, enhanced documentation, and the introduction of custom CSS properties, an expanded color palette, and customizable utilities API, among others.
Getting Started with Bootstrap 5
Before diving into the world of Bootstrap 5, it’s essential to note that this alpha release is not yet stable and should not be used in production environments. To get started, you’ll need to install Bootstrap into your React project. If you’re new to React, you can find instructions on setting up a project here.
Installing Bootstrap
There are several ways to install Bootstrap, including downloading the source files, using the CDN, or installing via package managers like Yarn or npm. For this tutorial, we’ll use Yarn. Run the following command in your project’s root directory to install Bootstrap 5 and the icons package:
Setting Up a Workflow with Sass
To make Sass available in your React project, you’ll need to install node-sass. Create a src/main.scss folder and import the Bootstrap source stylesheet into it. This will allow you to compile Sass into CSS and create a CSS folder containing all your Bootstrap packages.
Building a React Login Page
Let’s build a simple sign-up page using Bootstrap to demonstrate some of the new features. Create a user sign-up form with regular Bootstrap 4 classes, and then customize it using Bootstrap 5 features.
Customizations
One of the most significant advantages of Bootstrap 5 is its customizability. You can override default Bootstrap variables to give your form a unique look and feel. Update the src/main.scss file to change the primary color variable from blue to black, and watch how the button’s color changes accordingly.
Utilities API
The Utilities API allows you to change or extend Bootstrap’s utility classes. Create a new custom utility to modify the margin-bottom property on your form elements. This feature gives you unparalleled control over your project’s design.
Icons
Bootstrap 5 comes with a custom icons library, which includes scalable SVG icons that can be easily customized using CSS. Install the icon library and update your App.js file to add icons to your form fields. You can use the icons as external images or style them using CSS.
Styling Icons
The Bootstrap icons can accept a class attribute for further styling using CSS. Update your index.css file to style the icons, and add the class attribute to individual icons to exert the styling effects.
What’s Next?
The Bootstrap team has done an excellent job with this new release, but remember that it’s still in beta and subject to changes. Feel free to experiment with it and share your experiences. Get set up with LogRocket’s modern React error tracking to create better digital experiences.
