Is it possible to center text in select box?

Answer 1

That's for align right. Try it:

select{
    text-align-last:right;
    padding-right: 29px;
    direction: rtl;
}

the browser support for the text-align-last attribute can be found here: https://www.w3schools.com/cssref/css3_pr_text-align-last.asp It looks like only Safari is still not supporting it.
