link subscrevendo | Bootstrap: criação de uma single-page responsiva

Bom dia, estou com um problema de conflito de estilos, criei um rodape em um outro arquivo e ai quando dou um 'require_once' pro meu index, o estilo se sobscreve e a pagina até perde varias funções, o arquivo do rodape é o seguinte: `

<head>
    <link rel="stylesheet" id="compiled.css-css"
        href="https://mdbootstrap.com/wp-content/themes/mdbootstrap4/css/compiled-4.19.1.min.css?ver=4.19.1"
        type="text/css" media="all">
</head>


<body>
    <footer class="page-footer font-small special-color-dark pt-4">

    ....

    </footer>
</body>

```

E o index no qual estou tentando colocar ele é:

<!DOCTYPE html>
<html lang="pt-br">

<head>
    <meta charset="utf-8">
    <meta http -equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <link rel="stylesheet" href="https://unpkg.com/bootstrap-table@1.16.0/dist/bootstrap-table.min.css">

    <link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">
</head>

<body id="body">
    <div class="table responsive">
        <div class="container">
            <table id="tabela_dividas"><br>
                <?php
                if (is_admin()) { ?>
                    <h2>Gerar dividas</h2>
                    <p><button type="button" class="btn btn-danger" onclick="abriModalDividas()">
                            Gerar Divida
                        </button></p>
                    <thead>
                        <tr>
                            <th scope="col" data-field="id_cad" data-visible="false"></th>
                            <th scope="col" data-field="divida" data-checkbox="true"></th>

                            <th scope="col" data-field="tipo_negocio">tipo de negocio</th>
                        </tr>
                    </thead>
                <?php } else { ?>
                    <h2>Dividas</h2>
                    <p><button type="button" class="btn btn-danger" onclick="abriModalDividas()">
                            Negociar dividas
                        </button></p>
                    <thead>
                        <tr>
                            <th scope="col" data-field="id_dividas" data-visible="false"></th>
                            <th scope="col" data-field="divida" data-checkbox="true"></th>
                            <th scope="col" data-field="nome">Nome</th>
                            <th scope="col" data-field="tipo_divida">Tipo de dividas</th>
                            <th scope="col" data-field="valor">Valor</th>

                        </tr>
                    </thead>
                <?php
                }
                ?>

            </table>
        </div>
    </div>

    <?php require_once 'rodape.html'?>
</body>

Como consigo resolver isso? Imagino que deve haver algum jeito de isolar esse link que está chegando do rodape pra um não sobscrever o outro ou sla oque.
