2 button show hide with opacity fade

2 button show hide with opacity fade

Here is what I'm trying to achieve:

On load:
div.content is hidden
input.hide is hidden

On press of input.show:
div.content appears
input.hide appears
input.show fades to 30% opacity

On press of input.hide:
div.content hides
input.hide hides
input.show turns to full 100% opacity.

<input type="image" class="show"  src="/image/show.png"/>
<input type="image" class="hide"  src="/image/hide.png"/>
<div class="content">Content Here</div>


Any help would be much appreciated
