How to make a reactive table in CSS

I have tried the piece of code mentioned below for a table, but it doesn't make it responsive. Can anyone make modifications to this code to make it responsive?

.content table {
    border-collapse:collapse;
    margin:0 0 1.625em;
    width:100%;
    font-size:90%
}
.content table h3 {
    font-size:1em;
    font-weight:300
}
.content tbody {
    border-bottom:1px solid #444;
    border-left:1px solid #444
}
.content tr:nth-child(odd) {
    background-color:#eee
}
.content table th {
    background-color:#0078d7;
    color:#fff;
    font-size:.85em
}
.content td,.content th {
    vertical-align:top
}
.content th,.content td {
    padding:3px 10px;
    text-align:left;
    border-top:1px solid #444;
    border-right:1px solid #444
}

$menu .= '<table class="content"><thead><tr><th>Name</th><th>Description</th>‌​<th>Price</th></tr><‌​/thead>'; 

while ( have_rows('sections_items') ) : the_row();
    // Your loop code
    $menu .= '<tr><td>'.get_sub_field('dish_names').'</td><td>'.get_sub_f‌ield('dish_descripti‌​on').'</td><td>$ '.get_sub_field('dish_price').'</td></tr>';
endwhile;

$menu .= '</table> ';

What I did for showing table on mobile was either using bootstrap grid feature or modify table display style. I use them both depending on the content I want to show.

The key is to add @media query so that it changes based on screen size:

@media (max-width: 767px){
    table{
        //styles you want to change
    }
}

If you have to use table elements, you can change the style of table and td elements to display: block on mobile and modify them from then.

Another way to do this which is not recommended is to create a whole new view for mobile only and hide the original table using media query. This creates duplicate data but gives you the freedom to custom mobile view at will.

example:

.mobile-table{ // or whatever class you want
    display: none;
}

@media (max-width: 767px){
    table{
        display: none;
    }
    .mobile-table{
        display: block;
    }
}
