I want to add a custom logo indeed.View attachment 3631 Is this all you want? Or is there a custom logo you're using?
color: black;
The little trick with the dot point white works, but the image is cropped. The size is 52*31 px.I myself would edit the header.php as I use child-themes ... but you could just change "color: black" to what ever the colour background of the page is (#ffffff "white" maybe?) and put a "." in the text field. The "." would be the same colour and you won't see it.
Don't know what it would look like though ... try it.
