I am not into the CSS game anymore, if anything needs to be done I'd just go with whatever widgets any CSS framework offers, but why has it been so hard for so long to center things with CSS (I believe flexbox finally fixed it) ?
The <center> element is obsolete and is not in the HTML5 spec...
You’re right of cause and centering is styling and it doesn’t belong in the html. It just that sometimes I really can’t be bothered with css and the center hr and a ton of br slips in, and it works well enough.
