Blogger theme image set

When you use the Contempo theme from Blogger you could find out the logo stretching, or being too large. Don't complain. There's a workaround for this and it's adding this CSS Code in Theme Layout > Advanced (the values in pixel are arbitrary for an image logo of 300 x 100 px):

.header-widget img{
width:300px;
min-width:300px;
height:100px;
}
.header-image-wrapper {
min-width:300px;
}
