I just had to do this myself, you need to do it the other way around.
<div>
<span class="icon icon-2x icon-camera" style=" vertical-align: middle;"></span>
<span class="my-text">hello world</span>
</div>
Of course you could not use inline styles and target it with your own css class. But this works in a copy paste fashion.
See here: Vertical alignment of text and icon in button
If it were up to me however, I would not use the icon-2x. And simply specify the font-size myself, as in the following
<div class='my-fancy-container'>
<span class='my-icon icon-file-text'></span>
<span class='my-text'>Hello World</span>
</div>
.my-icon {
vertical-align: middle;
font-size: 40px;
}
.my-text {
font-family: "Courier-new";
}
.my-fancy-container {
border: 1px solid #ccc;
border-radius: 6px;
display: inline-block;
margin: 60px;
padding: 10px;
}
