EDIT: I'm not sure what the issue was, but it seems to have resolved itself. Perhaps I forgot to update my manifest file. I have no idea what the problem was, but it is working now. :/
Here is an example of my html code:
<div id="well_comments_container" class="element_container" name='well_comments' type="textarea" require="0">
<label for="well_comment">What did we do really well?</label><br />
<textarea id="well_comment" name="well_comment" rows="4"></textarea>
</div>
Here is an example of my css code:
.element_container{
display: inline-block;
padding: .5em .5em;
}
.element_container[type="textarea"]{
width: 100%;
}
This works on a laptop just fine, but when I look at it on a touchpad it doesn't seem to work. It's width is clearly not 100% of the parent like it is in chrome.
Warmth.
