Welcome area logo not responsive

When I add a logo to the welcome are, on top of the fronpage, over the header image, the logo is not responsive.
On smaller screens it doesn’t scale down on size.

The logo is responsive, but it won’t scale down if it has enough space to fit the screen at the maximum width you’ve set for it from the options (in case you’ve set a width for it). If you would like it to be smaller on smaller screen sizes, let me know what those sizes are and I’ll give you some custom CSS.
