Horizontal align labe with checkbox and text

Im trying to align the checkboxes so the checkboxes will be aligned under each other. Now the text is aligned under each other. I would like it to be horizontally in the middle, but then with the checkboxes aligned straight under each other.

<ul class="berocket_aapf_widget  " data-scroll_theme="dark" style="display: block;">
    <li class="">
        <span>
            <input id="checkbox_44" class="checkbox_44" type="checkbox" data-term_id="44" data-taxonomy="pa_kleur" data-operator="OR"><label for="checkbox_44" class="berocket_label_widgets"> Blauw</label>
        </span>
    </li>
            <li class="">
        <span>
            <input id="checkbox_47" class="checkbox_47" type="checkbox" data-term_id="47" data-taxonomy="pa_kleur" data-operator="OR"><label for="checkbox_47" class="berocket_label_widgets"> Rood</label>
        </span>
    </li>
            <li class="">
        <span>
            <input id="checkbox_48" class="checkbox_48" type="checkbox" data-term_id="48" data-taxonomy="pa_kleur" data-operator="OR"><label for="checkbox_48" class="berocket_label_widgets"> Roze</label>
        </span>
    </li>
            <li class="">
        <span>
            <input id="checkbox_82" class="checkbox_82" type="checkbox" data-term_id="82" data-taxonomy="pa_kleur" data-operator="OR"><label for="checkbox_82" class="berocket_label_widgets"> Wit</label>
        </span>
    </li>
            <li class="">
        <span>
            <input id="checkbox_83" class="checkbox_83" type="checkbox" data-term_id="83" data-taxonomy="pa_kleur" data-operator="OR"><label for="checkbox_83" class="berocket_label_widgets"> Zwart</label>
        </span>
    </li>
            <li class="">
        <span>
            <input id="checkbox_84" class="checkbox_84" type="checkbox" data-term_id="84" data-taxonomy="pa_kleur" data-operator="OR"><label for="checkbox_84" class="berocket_label_widgets"> Groen</label>
        </span>
    </li>
            <li class="">
        <span>
            <input id="checkbox_86" class="checkbox_86" type="checkbox" data-term_id="86" data-taxonomy="pa_kleur" data-operator="OR"><label for="checkbox_86" class="berocket_label_widgets"> Multicolor</label>
        </span>
    </li>
            <li class="">
        <span>
            <input id="checkbox_10107" class="checkbox_10107" type="checkbox" data-term_id="10107" data-taxonomy="pa_kleur" data-operator="OR"><label for="checkbox_10107" class="berocket_label_widgets"> Taupe</label>
        </span>
    </li>
            <li class="berocket_widget_show_values" style="display: none;">Show value<span class="show_button"></span></li>
</ul>

Here is an example of what it looks like, the checkboxes are not aligned under each other.
