HTML buttons have special behaviour in CSS (not even styles, but differences in the rules how they work) that cannot be reset using a CSS reset. I actually tried to make a button fit into the reset of the UI until I gave up and used a div.
"button are special element and their content is always vertically aligned by default. Even all the propertise are the same, if you don't center the text in the link, you won't get the same visual"
