oren Hi, Three buttons looks great, but when adding the 4th one, it loses design. See: link: knbis.com
James Hi oren , Thanks for sharing a link to your site. I took a look at your site and it looks like there's a custom CSS that changes the size of the fourth button. If you remove this custom CSS the button should return back to normal.
James Glad to hear that you were able to find it! 😄 If you ever have any other issues, please let us know!
