Draw set of rectangles horizontally in HTML page in Laravel project?

I am doing web project Using Laravel 5. I used to blade template format to create views.

I take database some integer value (eg : 5) and also get specific colour code for that value(eg : red ,green e.t.c)

I want to draw rectangle for this number and put background colour to that rectangle. Now I use for-each loop and draw rectangles. but they are drawing vertically.

<section class="content fluid">
    <div class="row">
        <div class="box box-warning">
            @foreach($rooms as $room)

            <div style="width:50px;height:50px;border:1px solid #000;">{{$room->id }}</div><br/>


            @endforeach
