Javascript Remove attr

I'm pretty sure I can do this in Javascript but when a 'button' is clicked I would like it to remove some CSS Ids.

I havent started the Javascript course but I need to do this ASAP :-)

Hi Shaun,

you can do this easily using jQuery. Are you familiar with jQuery or looking for an pure JS solution? For jquery check this out: https://api.jquery.com/remove/

Well I wasen't sure If I could do this with pure CSS

After looking at the link can you do this:

onclick= $varible( ".content_overlay" ).remove();

For pure JS you could use: 

element.removeAttribute(attrName);

<div onclick="$('.content_overlay').remove();" id="view-button" >
                View <?php echo $heading_title  ?>
            </div>

I am finding it difficult to understand... .content_overlay is not an ID, it is a class. Why are you removing it? I assume you want to remove the ID #view-button?

If so try this and remove the 'onclick="$('.content_overlay').remove();"' part:

onclick = function() {
   this.removeAttribute(id);
}

Does this work?

Sorry the Content_overlay is an ID so its #content_overlay and when I click #view-button I want the #content_overlay to be removed

Okay, then try this:

onclick = function() { document.getElementById(content_overlay).removeAttribute(id); }

So I added this in:

<div onclick = function() { document.getElementById(content_overlay).removeAttribute(id); } id="#view_button" >
                View <?php echo $heading_title  ?>
            </div>

And the button doesn't show up now

#view_button{
    background-color: #666;
    box-shadow: 2px 2px 6px 0px rgba(102,102,102,0.64);
    text-align: center;
    font-family: "'QuattrocentoRomanRegular'";
    font-size: 25px;
    color: white;
    padding-top: 20px;
    margin:300px auto;
    padding-bottom: 20px;
    height: auto;
    width: auto;
    }
