Cross-browser custom styling for file upload button

Question

I m trying to style a file upload button to my personal preferences  but I couldn t find any really solid ways to do this without JS  I did find two other questions about this subject  but the answers there either involved JavaScript  or suggested Quirksmode s approach   My major issue with this Quirksmode s approach is that the file button will still have the browser-defined dimensions  so it won t automatically adjust to whatever s used as button that s placed below it  I ve made some code  based on it  but it will just take up the space the file button would normally take up  so it won t at all fill the parent div like I want it to   HTML    lt div class  myLabel  gt       lt input type  file   gt       lt span gt My Label lt  span gt   lt  div gt    CSS    myLabel       position  relative     myLabel input       position  absolute      z-index  2      opacity  0      width  100       height  100       This fiddle demonstrates how this approach is quite flawed  In Chrome  clicking the    below the second demo button will open the file dialog anyway  but also in all other browsers  the file button doesn t take up the correct areas of the button   Is there any more solid way to style the file upload button  without any JavaScript  and preferably using as little  hacky  coding as possible  since hacking usually brings other problems along with it  such as the ones in the fiddle

Please find below a way that works on all browsers. Basically I put the input on top the image. I make it huge using font-size so the user is always clicking the upload button.

.myFile {_x000D_
  position: relative;_x000D_
  overflow: hidden;_x000D_
  float: left;_x000D_
  clear: left;_x000D_
}_x000D_
.myFile input[type="file"] {_x000D_
  display: block;_x000D_
  position: absolute;_x000D_
  top: 0;_x000D_
  right: 0;_x000D_
  opacity: 0;_x000D_
  font-size: 100px;_x000D_
  filter: alpha(opacity=0);_x000D_
  cursor: pointer;_x000D_
}

_x000D_

<label class="myFile">_x000D_

  <input type="file" />_x000D_

Any easy way to cover ALL file inputs is to just style your input type button  and drop this in globally to turn file inputs into buttons     document  ready function            input type file    each function              var thisInput      this           var newElement       lt input type  button  value  Choose File    gt             newElement click function                 thisInput  click                        thisInput  after newElement           thisInput  hide                  Here s some sample button CSS that I got from http   cssdeck com labs beautiful-flat-buttons   input type button      position  relative    vertical-align  top    width  100     height  60px    padding  0    font-size  22px    color white    text-align  center    text-shadow  0 1px 2px rgba 0  0  0  0 25     background   454545    border  0    border-bottom  2px solid  2f2e2e    cursor  pointer    -webkit-box-shadow  inset 0 -2px  2f2e2e    box-shadow  inset 0 -2px  2f2e2e    input type button  active     top  1px    outline  none    -webkit-box-shadow  none    box-shadow  none

I just came across this problem and have written a solution for those of you who are using Angular  You can write a custom directive composed of a container  a button  and an input element with type file  With CSS you then place the input over the custom button but with opacity 0  You set the containers height and width to exactly the offset width and height of the button and the input s height and width to 100  of the container    the directive  angular module  myCoolApp      directive  fileButton   function          return         templateUrl   components directives fileButton fileButton html         restrict   E         link  function  scope  element  attributes             var container   angular element   file-upload-container            var button   angular element   file-upload-button             container css               position   relative               overflow   hidden               width  button offsetWidth              height  button offsetHeight                                     a jade template if you are using jade  div class  file-upload-container        button class  file-upload-button         input file-upload class  file-upload-input   type  file   onchange  doSomethingWhenFileIsSelected         the same template in html if you are using html   lt div class  file-upload-container  gt      lt button class  file-upload-button  gt  lt  button gt      lt input class  file-upload-input  id  file-upload  type  file  onchange  doSomethingWhenFileIsSelected      gt    lt  div gt    the css    file-upload-button       margin-top  40px      padding  30px      border  1px solid black      height  100px      width  100px      background  transparent      font-size  66px      padding-top  0px      border-radius  5px      border  2px solid rgb 255  228  0        color  rgb 255  228  0       file-upload-input       position  absolute      top  0      left  0      z-index  2      width  100       height  100       opacity  0      cursor  pointer

I m posting this because  to my surprise  there was no other place I could find that recommended this   There s a really easy way to do this  without restricting you to browser-defined input dimensions  Just use the  lt label gt  tag around a hidden file upload button  This allows for even more freedom in styling than the styling allowed via webkit s built-in styling 1    The label tag was made for the exact purpose of directing any click events on it to the child inputs 2   so using that  you won t require any JavaScript to direct the click event to the input button for you anymore  You d to use something like the following    x000D   x000D  label myLabel input type  file     x000D      position absolute  x000D      top  -1000px  x000D    x000D   x000D         Example custom styling        x000D   myLabel   x000D      border  2px solid  AAA  x000D      border-radius  4px  x000D      padding  2px 5px  x000D      margin  2px  x000D      background   DDD  x000D      display  inline-block  x000D    x000D   myLabel hover   x000D      background   CCC  x000D    x000D   myLabel active   x000D      background   CCF  x000D    x000D   myLabel  invalid   span   x000D      color   A44  x000D    x000D   myLabel  valid   span   x000D      color   4A4  x000D    x000D   lt label class  myLabel  gt  x000D       lt input type  file  required  gt  x000D       lt span gt My Label lt  span gt  x000D   lt  label gt  x000D   x000D   x000D    I ve used a fixed position to hide the input  to make it work even in ancient versions of Internet Explorer  emulated IE8- refused to work on a visibility hidden or display none file-input   I ve tested in emulated IE7 and up  and it worked perfectly      You can t use  lt button gt s inside  lt label gt  tags unfortunately  so you ll have to define the styles for the buttons yourself  To me  this is the only downside to this approach  If the for attribute is defined  its value is used to trigger the input with the same id as the for attribute on the  lt label gt
