Could someone tell me where I’m going wrong? the bootstrap and jquery order is correct and shows no error in the browser console but when I decrease the page size, the dropdown does not expand. code:

<!DOCTYPE html>
<html lang="pt-br">
<head>
    <meta charset="utf-8"/>
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie-edge">
    <title>@yield('titulo')</title>

<body>
    <nav class="navbar navbar-expand-lg navbar-light bg-light">
        <div class="container">
            <a class="navbar-brand" href="#">Aaa</a>
            <button type="button" class="navbar-toggler" data-
            toggle="collapse" data-target="#navbarSite">
            <span class="navbar-toggler-icon"></span>
        </button>

        <div class="collapse navbar-collapse" id="navbarSite">
            <ul class="navbar-nav ml-auto">
                <li class="nav-item">
                    <a class="nav-link" href="#">Home</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#">Contato</a>
                </li>
                <li class="nav-item">

  • It is not necessary to add SOLVED in the title, as can be seen in [tour], you just need to accept the answer that solved your doubt.

The error is here:

<button type="button" class="navbar-toggler" data-
            toggle="collapse" data-target="#navbarSite">

You gave a line break in the middle of the tag attributes, more specifically, "data-toggle" of button. It has to stay that way:

<button type="button" class="navbar-toggler" data-toggle="collapse" data-target="#navbarSite">

Working:

<!DOCTYPE html>
<html lang="pt-br">
<head>
    <meta charset="utf-8"/>
    <meta name="viewport" content="width=device-width, initial-scale=1.0">

            <span class="navbar-toggler-icon"></span>

        <div class="collapse navbar-collapse" id="navbarSite">

                <li class="nav-item">
