Set an inline style with javascript click [duplicate]

I’m trying to change the position of an element with some simple javascript. This isn’t working and I’ve no idea what I’ve got wrong or if what I expect is not possible. This doesn’t need to be pretty, it’s for internal use only.COT

<div id="container">
    <div id="maps"> 
        <div class="frida">CONTENT</div> 
        <div class="dolores">CONTENT</div>
    </div>
    <a href="" onclick = document.getElementById("maps").style.left = "0"; >FRIDA</a> 
    <a href="" onclick = document.getElementById("maps").style.left = "-100vw"; >DOLORES</a>
</div>
