How to center text inside anchor tag

Question

I want my anchor tag look like a button, and created this style JsFiddle

.details-button {
    background: linear-gradient(to bottom, #FFFFFF 0, #FAB149 2%, #F89406 100%) repeat scroll 0 0 transparent;
    border: 1px solid #FAB149;
    -ms-border-radius: 3px;
    border-radius: 3px;
    -webkit-box-shadow: 0 1px 2px #999999;
    -ms-box-shadow: 0 1px 2px #999999;
    box-shadow: 0 1px 2px #999999;
    color: #FFFFFF;
    cursor: pointer;
    font-family:"Helvetica Neue", Helvetica, Arial, sans-serif;
    font-size: 13px;
    font-weight: bold;
    -ms-text-shadow: 0 -1px #099FDF;
    text-shadow: 0 -1px #099FDF;
    margin: 4px;
    height: 28px;
    width: 85px;
    vertical-align: central;
    align-items: center;
    text-decoration: none;
    font: menu;
    display: inline-block;
    /*padding: 6px 0 5px 18px;*/
}

It looks as I want, but how to center text horizontally and vertically inside anchor tag?

Answer 1

Add

text-align: center;
line-height: 28px;

Answer 2

line-height and padding work if the height of the element is hard-coded, but I like to use

{
  display: flex;
  flex-direction: column;
  justify-content: center;
  text-align: center;
}

to keep text centered in a tags where the height may change.
