No you do not understand. Probably because of my bad English
I do not want that the logo be downsize by the width of, on the contrary, I want them him to NOT be limited.
Maybe your advice is not suitable for template by Jumla 3?
I replaced in file "template-blue.css" the code
#yt_header #yt_logoposition h1 a {
display: inline-block;
min-height: 37px;
}
on the code
#yt_header #yt_logoposition h1 a {
display: inline-block;
min-height: 37px;
max-width:100%;
}
But this does not help, the logo is not increased. Image and even text continues to be limited in width.
