Logo Size in Manuscript Theme

Software Support
1

Hello guys.
I`ve been looking into the forum for a solution on how to make my logo in Manuscript theme larger.
Aparently i have to modify the following code in css:

.pkp_site_name .is_img img

However there is not this specific piece of code in the header.less of this theme. I`ve tried some changes in the code below, like:
@media(min-width: @screen-desktop) {
width: 200%;
margin-left: 0;
}
With no effect.
I have little knowledge about css, so if someone can give a help i would apreciate.
