The minimal setup to get up and running.
HTML starter template
Be sure to have your pages set up with the latest design and development standards. That means using an HTML5 doctype and including a viewport meta tag for proper responsive behaviors. Put it all together and your pages should look like this:
<!doctype html> <html lang="en"> <head> <!-- Required meta tags --> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1"> <!-- Your CSS --> <link href="/path/to/styles.css" rel="stylesheet"> <title>Hello, world!</title> </head> <body> <!-- Bootstrap Bundle with Popper --> <script src="https://email@example.com/dist/js/bootstrap.bundle.min.js" integrity="sha384-p34f1UUtsS3wqzfto5wAAmdvj+osOnFyQFpp4Ua3gs/ZVWx6oOypYoCJhGGScy+8" crossorigin="anonymous"></script> </body> </html>
Bootstrap requires the use of the HTML5 doctype. Without it, you’ll see some funky incomplete styling, but including it shouldn’t cause any considerable hiccups.
<!doctype html> <html lang="en"> <!-- ... --> </html>
Responsive meta tag
Bootstrap is developed mobile first, a strategy in which we optimize code for mobile devices first and then scale up components as necessary using CSS media queries. To ensure proper rendering and touch zooming for all devices, add the responsive viewport meta tag to your.
