Change logo size in header

Hello,

I'd like to make the logo in the header bigger. I have already tried changing the grid in header.php and adding adding the custom css I've used with some of your other sites. But the logo size has not changed.

 

Hello,

Paste this code in Custom CSS
Appearance > Theme Option > Styling Option > Custom CSS

Code:

.header .logo img{
max-width:350px;
}

Adjust its value as per your requirements.

 

Thanks!
