Align Text Center

I added class='text-center' for inputs but input type number and input type text are differently centered. Also the content is not aligned inside the checkboxes. How can i make everything centered?

Checkbox Input:

<td>
    <div class="checkbox checkbox-success">
        <input class="text-center" id="required1" type="checkbox" checked="" disabled="">
        <label for="required1"></label>
    </div>
</td>

Text Input

<td>
    <input class="text-center" name="Fields" type="text" value="USD">
</td>

Number Input

<td>
    <input class="text-center" name="Fields" type="number" value="100">
</td>
