checkbox css/jquery style change

The purpose of my codes is to change the <td> portion of the color and the font inside the table when I check/unchecked the box, but it didn't work as intended with the code I got from here.

input[type=checkbox] + td {
    background-color: #FFFFFF;
    color:#000000
} 

input[type=checkbox]:checked + td {
    background-color: #00447C;
    color:#FFFFFF;
} 

<div id="details">
    <div class="container">
        <p>Example</p>
        <table id="table">
          <tr>
            <th></th>
            <th>Header 1</th>
            <th>Header 2</th>
          </tr>
          <tr>
            <td> <input type="checkbox"/></td>
            <td>element1</td>
            <td>detail1</td>
          </tr>
          <tr>
            <td> <input type="checkbox"/></td>
            <td>element2</td>
            <td>detail2</td>
          </tr>
          <tr>
            <td> <input type="checkbox"/></td>
            <td>element3</td>
            <td>detail3</td>
          </tr>
        </table>
        <button class="button">Reset</button>
    </div>  
</div>

It works in the source so I am confused regarding this.
