Hi
You must edit this in the style.css file. >theme >edit >style.css. Remember to edit both columns to match your total width. The numbers appear more than one place, so you will have to “look around” Use your browsers search capacity to find the numbers. If you copy the entire text into a document before you do anything, it is easy to put it back in case of “accidents” 😉
hope this helps and that it is in the “way of the KeyMaster”
