Supposing div is  div and button is  button     div       display  table-cell      width  100       height  100       text-align  center      vertical-align  center      button      Then nest the button into div as usual

Margin  0 auto  is the correct answer for horizontal centering only  For centering both ways something like this will work  using jquery   var cenBtn   function        var W     window  width       var H     window  height       var BtnW   insert button width     var BtnH   insert button height     var LeftOff    W   2  -  BtnW   2      var TopOff    H   2  -  BtnH  2              buttonID   css  left  LeftOff  top  TopOff          window  bind  load  resize   cenBtn       Update     five years later  one could use flexbox on the parent DIV element to easily center the button both horizontally and vertically     Including all browser prefixes  for best support  div     display  -webkit-box    display  -moz-box    display  -ms-flexbox    display  -webkit-flex    display  flex    -webkit-box-align   center    -moz-box-align      center    -ms-flex-align      center    -webkit-align-items   center    align-items   center     justify-content   center    -webkit-justify-content   center    -webkit-box-pack   center    -moz-box-pack   center    -ms-flex-pack   center       x000D   x000D   container   x000D    position  relative  x000D    margin  20px  x000D    background  red  x000D    height  300px  x000D    width  400px  x000D    x000D   x000D   container div   x000D    display  -webkit-box  x000D    display  -moz-box  x000D    display  -ms-flexbox  x000D    display  -webkit-flex  x000D    display  flex  x000D    -webkit-box-align  center  x000D    -moz-box-align  center  x000D    -ms-flex-align  center  x000D    -webkit-align-items  center  x000D    align-items  center  x000D    justify-content  center  x000D    -webkit-box-pack  center  x000D    -moz-box-pack  center  x000D    -ms-flex-pack  center  x000D    -webkit-justify-content  center  x000D    justify-content  center  x000D    x000D   lt  -- using a container to make the 100  width and height mean something -- gt  x000D   lt div id  container  gt   x000D     lt div style  width 100   height 100   gt  x000D       lt button type  button  gt hello lt  button gt  x000D     lt  div gt  x000D   lt  div gt  x000D   x000D   x000D

Updated Answer  Updating because I noticed it s an active answer  however Flexbox would be the correct approach now   Live Demo  Vertical and horizontal alignment    wrapper     display  flex    align-items  center    justify-content  center      Just horizontal  as long as the main flex axis is horizontal which is default    wrapper     display  flex    justify-content  center      Original Answer using a fixed width and no flexbox  If the original poster wants vertical and center alignment its quite easy for fixed width and height of the button  try the following  Live Demo  CSS  button      height 20px       width 100px       margin  -20px -50px       position relative      top 50        left 50       for just horizontal alignment use either  button      margin  0 auto      or  div      text-align center

You could just make    x000D   x000D   lt div style  text-align  center  border  1px solid  gt  x000D     lt input type  button  value  button  gt  x000D   lt  div gt  x000D   x000D   x000D    Or you could do it like this instead    x000D   x000D   lt div style  border  1px solid  gt  x000D     lt input type  button  value  button  style  display  block  margin  0 auto   gt  x000D   lt  div gt  x000D   x000D   x000D    The first one will center align everything inside the div  The other one will center align just the button
