How to set right position to elements? - html

Question

I have a window that pops up after a button is clicked. In this window, in the modal's header, I want to realize switcher that has position between two words, "оn", and ,""off. But it looks like this now:
There is a such sequence now: "on"-checkbox element-"off"-switcher, but I want "on"-switcher-"off". How can I fix it?
html:
<button data-modal-target="#modal" id="employee_tbl_btn" data-table-url="{% url 'ajax_table_data' %}">Open Window</button>
<div class="modal" id="modal">
<div class="modal-header">
<div class="item">
<label class="switch">
<label for="a">on</label>
<input type="checkbox" id="a" class="switch">
<span class="slider round"></span>
<label for="a">off</label>
</label>
</div>
</div>
<div class="modal-body">
<table id="employee_tbl" class="styled-table"></table>
</div>
</div>
