I'm having proble to load some image from db and css in laravel

I just made a project in laravel, some functions just worked normally, but in one .blade, the data didn't show up and the .css did't work.

<div class="row row-centered">
                @foreach ($profils as $profil)
                <div class="col-md-4" >
                    <div class="card" style="width: 18rem;">
                        <center>
                            <div class="card-img-top bg-secondary">
                                <img class="card-img-top" src="" width="150 "> 
                            </div>   
                        </center>
                      <div class="card-body" style="padding: 10px;">
                        <h5 class="card-title"></h5>
                        <p class="card-text"></p>
                        <p class="card-text"></p>
                      </div>
                    </div>
                </div>
                @endforeach
            </div>

But, it worked well in my teams laptop (firefox). Can you guys give some sugestions here, thanks
