<!DOCTYPE html> <html> <head> <title>Bootstrap Forms</title> <meta name = "viewport" content = "width = device-width, initial-scale = 1"> <link rel = "stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.1/css/bootstrap.min.css"> <script src = "https://cdn.staticfile.org/jquery/3.3.1/jquery.min.js"></script> <script src = "https://stackpath.bootstrapcdn.com/bootstrap/4.1.1/js/bootstrap.min.js"></script> </head> <body> <label for = "name">Favourite TV Series</label> <div class = "radio"> <label> <input type = "radio" name = "optionsRadios" id = "optionsRadios1" value = "option1" checked> Suits </label> </div> <div class = "radio"> <label> <input type = "radio" name = "optionsRadios" id = "optionsRadios2" value = "option2"> House of Cards </label> </div> </body> </html>
