Signature's look different on phones and computers

[zanderklocke]

I've noticed that a lot more of the signature shows up on the computer than a mobile device. Furthermore, I cannot for the life of me figure out if there is a way to change the text size of links in signatures to be able to fit more stuff in my signature?

Are these changes to the amount of space that can be used in a forum signature permanent or is this a forum bug?
