2 questions regarding this

Hello,

When I visit my page using my mobile it displays two, not one (which my laptop shows correctly). It just shows the thermometer twice, which I am wondering how do I fix?

Also, how do I center it?

PS. It would be nice to see the ability to have text around by the side, it doesn’t allow it currently.
