Mailchimp CSS code trouble

[Simplifyadmin]

Hi!
So I'm trying to get one line of text in the header to stay on one line when viewed on mobile devices, I've tried everything but just can't get it to stay on the one line.
Anyone able to help me?

I used the following code:

<style type="text/css">@media only screen and (max-width: 480px){ .bodyContent{display: inline-block !important;} } </style>
