<span class="helper"></span> - what does it do?

[Luxus]

I am currently customizing XF and noticed an empty <span class="helper"></span> in the footer template. I couldn't figure out what purpose it has. I want to make the html as clean as possible, so I don't know if I can remove it or not.

Thanks for help

It enables styling. It doesn't hurt anything. Just leave it there.
