Hopefully this is an easy question. I have a `div` that I want to toggle hidden/shown with a button

```
<div id="newpost">

```

Here's a plain Javascript way of doing toggle:

```
<script>
  var toggle = function() {
  var mydiv = document.getElementById('newpost');
  if (mydiv.style.display === 'block' || mydiv.style.display === '')
    mydiv.style.display = 'none';
  else
    mydiv.style.display = 'block'
  }
</script>

<div id="newpost">asdf</div>
<input type="button" value="btn" onclick="toggle();">

```
You could use the following:

`mydiv.style.display === 'block' = (mydiv.style.display === 'block' ? 'none' : 'block');`
