Didn't found the "display: block;" line in the default theme's light CSS. I only had this:
.attachment_name {
border-bottom: none;
}
.attachment_details {
border-top: none;
border-radius: 0 0 .5em .5em;
}
I changed it to:
.attachment_name {
border-bottom: none;
display: inline-block;
}
.attachment_details {
border-top: none;
border-radius: 0 0 .5em .5em;
display: inline-block;
}
Still looks the same. No difference. My custom CSS file doesn't have this code at all, so that should not be a problem, right?
