I made some corrections in the style sheet to support the customization of the author box, values for this widget were fixed in the code, and now follow the changes that the user makes directly in WordPress customization panel.
In addition I also pulled out the edges of the footer widgets, now there is no longer a separation between the items in the footer, leaving the cleaner display.
The background image as I had commented, won new settings so that you can opt for side-by-side or fixed images.
I found a problem in functions.php that cause a crash in WordPress Panel and show an error message about the headers cannot be modified.
The problem was solved and version 1.77 of Careta coming soon.
