Using Bootstrap CSS & JS
Using Bootstrap CSS & JS¶
Want to use Bootstrap (or something similar) in your project? No problem!
First, install it. To be able to customize things further, we’ll install
bootstrap:
1 | $ yarn add bootstrap --dev
|
Importing Bootstrap Styles¶
Now that bootstrap lives in your node_modules/ directory, you can
import it from any Sass or JavaScript file. For example, if you already have
a global.scss file, import it from there:
1 2 3 4 5 6 7 | // assets/css/global.scss
// customize some Bootstrap variables
$primary: darken(#428bca, 20%);
// the ~ allows you to reference things in node_modules
@import "~bootstrap/scss/bootstrap";
|
That’s it! This imports the node_modules/bootstrap/scss/bootstrap.scss
file into global.scss. You can even customize the Bootstrap variables first!
Tip
If you don’t need all of Bootstrap’s features, you can include specific files
in the bootstrap directory instead - e.g. ~bootstrap/scss/alert.
Importing Bootstrap JavaScript¶
Bootstrap JavaScript requires jQuery and Popper.js, so make sure you have this installed:
1 | $ yarn add jquery popper.js --dev
|
Now, require bootstrap from any of your JavaScript files:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | // app.js
const $ = require('jquery');
// this "modifies" the jquery module: adding behavior to it
// the bootstrap module doesn't export/return anything
require('bootstrap');
// or you can include specific pieces
// require('bootstrap/js/dist/tooltip');
// require('bootstrap/js/dist/popover');
$(document).ready(function() {
$('[data-toggle="popover"]').popover();
});
|
Using other Bootstrap / jQuery Plugins¶
If you need to use jQuery plugins that work well with jQuery, you may need to use Encore’s autoProvidejQuery() method so that these plugins know where to find jQuery. Then, you can include the needed JavaScript and CSS like normal:
1 2 3 4 5 6 7 | // ...
// require the JavaScript
require('bootstrap-star-rating');
// require 2 CSS files needed
require('bootstrap-star-rating/css/star-rating.css');
require('bootstrap-star-rating/themes/krajee-svg/theme.css');
