Mobile Logo – size reduction also scales down shrinked logo

Hello,
I have the following css code to scale down the logo on a specific sreen size.
Unforunatley this also scales down the shrinked logo.
What can I do to make the shrinked logo always the same size?

@media only screen and (max-width: 1110px) and (min-width: 990px) {

	/* Logo verkleinern */
	.responsive #top .logo img { max-width: 78% !important; padding-top: 15px !important; }
}

Best regards,
Neverlands
