Answer 1

这一行：

<button class="btn btn-success ml-2 mt-2 data-bs-toggle="modal" data-bs-target="#loginModal">login </button>
                                        ^

缺少双引号。应该是：

<button class="btn btn-success ml-2 mt-2" data-bs-toggle="modal" data-bs-target="#loginModal">login </button>
                                        ^
