Answer 1

In this line:

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

There is double quote missing. It should be:

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