We don’t use the HTML5 element, ensuring you can stack progress bars, animate them, and place text labels over them. If React is the most-used JavaScript framework for building web applications, Bootstrap is the most popular CSS framework, powering millions of websites on the internet. In this tutorial, we will review how to add Bootstrap to React according to the latest version of both frameworks. We’ll also learn how to use the React-Bootstrap and Reactstrap packages to provide Bootstrap components for a React application. Here, we’re using the map-merge method to merge our custom map with the existing $theme-colors map.
This tutorial will help you with the knowledge and skills to create stunning and responsive websites. Used for creating the CSS animations for .progress-bar-animated. At the moment, when you open your sample site in a browser, you should simply see a blank page. In order to teach you Bootstrap, in this tutorial we will build a landing page with different elements so we can show you many use cases of the front-end framework. Check out the documentation of the packages we used in this tutorial to find out more ways they can be used. The source code for all the demo apps in this tutorial can be found on GitHub.
The takeaway: when to use Bootstrap
Axios is a promise-based HTTP client for the browser and Node.js. The only change we’ve made to this file is getting rid of the CRA starter page and making it render our ThemeSwitcher component instead. In the following section, we’ll review how to add Bootstrap to React apps.
Luckily, Bootstrap comes with comprehensive documentation, so it’s easy to look up how each bit of code works in detail. The documentation even includes samples of code, making it easier for beginners to pick up Bootstrap. As mentioned above, Bootstrap does all the work here by providing a mobile grid system that can adapt to any device and screen resolution. And, with Bootstrap, it’s easy to mark elements of your web page that are only visible to desktop, tablet, or mobile viewers.
Create Additional Pages
For example, a full Bootstrap modal component can now be easily imported as in our React application. The third way to add Bootstrap to a React app is to use a package that has prebuilt Bootstrap components designed to work as React components. Open-source products are great, but what happens when you have a problem?
- As shown in this demo, we are using a dropdown component that is available in Bootstrap to implement our theme switcher.
- Add .progress-bar-animated to .progress-bar to animate the stripes right to left via CSS3 animations.
- In the following section, we’ll review how to add Bootstrap to React apps.
- When you now save the file, any browser that opens it will automatically load the Bootstrap assets.
- Get started by including Bootstrap’s production-ready CSS and JavaScript via CDN without the need for any build steps.
- Check out the documentation of the packages we used in this tutorial to find out more ways they can be used.
You only set a height value on the .progress container, so if you change that value, the inner .progress-bar will automatically resize accordingly. Forms are the gateway for interaction between users and web services. As the complexity of data collection increases, so does the need for more user-friendly form interfaces. A multi-step form, by breaking down the data collection process into manageable chunks, enhances user experience and improves form completion rates. We will going to create a multi-step form in Bootstrap5 and JavaScript.
The good news: advantages of Bootstrap
Thanks to these options, it’s no longer necessary to use a DOM library, such as jQuery, to build web apps. While it’s possible to customize your Bootstrap site, most people stick with the basic design layout. So, unless you’re willing to put in the extra time and effort to customize Bootstrap, keep in mind that your website will look just like a lot of existing websites. Responsive websites are pages that easily adapt to different devices, platforms, and screen sizes.
We imported three components from the React-Bootstrap package; namely, Button, ButtonGroup, and Dropdown. And just like we did previously, we used the useState Hook to create our theme state and defined a function that set the value of theme to null. In addition, if you’re a frontend developer, you’ve almost certainly used or at least heard about Bootstrap, Foundation, and Bulma. These are all responsive (mobile-first) CSS frameworks with robust features and built-in utilities. There are many JavaScript frameworks you can choose from, including Angular, React, Vue.js, Ember, and so many more.
A Beginner’s Guide to Bootstrap
Since its initial version in 2011, Bootstrap’s had several updates that added major features (such as navigation options). They’ve also added more browser support and changed some fundamental parts of the framework (such as what is bootstrap used for switching from LESS to SASS for styling). Bootstrap is an open-source framework used for creating responsive, mobile-first sites. We know that’s a mouthful, so let’s go through the parts of that definition one by one.
In this article, we’ll go through a brief overview of Bootstrap along with its strengths and weaknesses. Bootstrap uses HTML elements and CSS properties that require
the HTML5 doctype. If that looks like what’s in your file and you saved your work, you are now ready to move on to the next step. Again, make sure the path corresponds to your location and version of jQuery. To get Bootstrap into your page, simply paste the code below into the section of your template. With Bootstrap, you can conjure complex web pages from standard HTML and customize them to your needs.
It’s worth mentioning that React-Bootstrap doesn’t come pre-installed with Bootstrap itself. The package only exports common Bootstrap classes as React components, which is why we could also see Bootstrap appended in the installation command above. Using React’s useState Hook, we created a state theme and set its initial value to null, as well as defined the setTheme method to modify this state. Then we created a resetTheme function that resets the theme’s value to null. If you’re considWeering a career as a Front-End Developer, you’ll definitely want to be familiar with Bootstrap.
In this example, we see how easy it is to use Bootstrap’s built-in classes and components in our React app. You can include multiple progress components inside a container with .progress-stacked to create a single stacked progress bar. Note that in this case, the styling to set the visual width of the progress bar must be applied to the .progress elements, rather than the .progress-bars. Progress components are built with two HTML elements, some CSS to set the width, and a few attributes.
Bootstrap helps you create responsive websites
In the code above, we simply included the Header, SideCard, and Post components in the App component. Notice how we used a couple of responsive utility classes provided by Bootstrap to adapt our app to different screen sizes. In the code above, we created a very simple theme switcher component using Bootstrap’s dropdown component and a few built-in classes. As shown in this demo, we are using a dropdown component that is available in Bootstrap to implement our theme switcher. We are also using the built-in button classes to set the size and color of the dropdown button.
