You could do like this, if you want to display and hide particular div on click of button.

<style>
.hidden{
    display:none;
}

.unhidden{
    display:block;
}
</style>
<script type="text/javascript">
function unhide(clickedButton, divID) {
var item = document.getElementById(divID);
if (item) {
    if(item.className=='hidden'){
        item.className = 'unhidden' ;
        clickedButton.value = 'hide'
    }else{
        item.className = 'hidden';
        clickedButton.value = 'unhide'
    }
}}

</script>

<body>
<div id="about" class="hidden">
<div class="content3">
<p>This is the about section.</p>
<p>It is currently still being worked on.</p>
</div>
</div>
<input type="button" onclick="unhide(this, 'about') " value="unhide">
</body>

UPDATE: Pass the other div id which you want to make disappear on click of div one. Please update your code with below's code.

SCRIPT

<script type="text/javascript">
    function unhide(divID, otherDivId) {
    var item = document.getElementById(divID);
    if (item) {
            item.className=(item.className=='hidden')?'unhidden':'hidden';
        }
        document.getElementById(otherDivId).className = 'hidden';
    }
</script>

HTML

<p style="padding-top:20px">
    <a href="javascript:unhide('link', 'about')" class="button">This is a link</a><br><br>
    <a href="javascript:unhide('about', 'link')" class="button">About</a>
</p>

I don't understand your question properly. But if you are trying to make different div elements visible upon clicking different links, then this is what you should do:

<div id = "anchor-div">
      <ul>
        <li> <a id="about-anchor" href="javascript:;"> About</a> </li> 
        <li> <a id="help-anchor" href="javascript:;"> Help </a> </li>
      </ul>
</div>


<div id="content-div">
       <div id="about-content"></div>
       <div id="help-content"></div>
</div>

$(document).ready(function(){

        //if you wish to keep both the divs hidden by default then dont forget to hide //them           
        $("#help-content").hide();
        $("#about-content").hide();

       $("#about-anchor").click(function(){
             $("#help-content").hide();
             $("#about-content").show();
        });

      $("#help-anchor").click(function(){
              $("#help-content").show();
             $("#about-content").hide();
       });
});

Also don't forget to add jQuery library.
