On FF, the rendered span height is 18px while on chrome it is 16px.
Why the difference and how to have consistent rendering across browsers.
HTML:
<span>Different height span</span>
CSS:
span {
font-size: 15px;
line-height: 2;
box-sizing: border-box;
}
Edit: Removing the line-height and box-sizing properties as they don't seem to any difference at all. https://jsfiddle.net/so2n0a8s/2/
