Here is one way which I like because it makes the input fill out the whole container. The trick is the "font-size: 100px", and it need to go with the "overflow: hidden" and the relative position.

<div id="upload-file-container" >
   <input type="file" />
</div>

#upload-file-container {
   width: 200px;
   height: 50px;
   position: relative;
   border: dashed 1px black;
   overflow: hidden;
}

#upload-file-container input[type="file"]
{
   margin: 0;
   opacity: 0;   
   font-size: 100px;
}

Something like that maybe?

<form>
  <input id="fileinput" type="file" style="display:none;"/>
</form>
<button id="falseinput">El Cucaratcha, for example</button>
<span id="selected_filename">No file selected</span>

<script>
$(document).ready( function() {
  $('#falseinput').click(function(){
    $("#fileinput").click();
  });
});
$('#fileinput').change(function() {
  $('#selected_filename').text($('#fileinput]')[0].files[0].name);
});

</script>

to show path of selected file you can try this on html :

<div class="fileinputs">
    <input type="file" class="file">
</div>

and in javascript :

        var fakeFileUpload = document.createElement('div');
        fakeFileUpload.className = 'fakefile';
        var image = document.createElement('div');
        image.className='fakebtn';
        image.innerHTML = 'browse';
        fakeFileUpload.appendChild(image);
        fakeFileUpload.appendChild(document.createElement('input'));
        var x = document.getElementsByTagName('input');
        for (var i=0;i<x.length;i++) {
            if (x[i].type != 'file') continue;
            if (x[i].parentNode.className != 'fileinputs') continue;
            x[i].className = 'file hidden';
            var clone = fakeFileUpload.cloneNode(true);
            x[i].parentNode.appendChild(clone);
            x[i].relatedElement = clone.getElementsByTagName('input')[0];
            x[i].onchange = x[i].onmouseout = function () {
                this.relatedElement.value = this.value;
            }
        }

and style :

div.fileinputs {
    position: relative;
    height: 30px;
    width: 370px;
}
input.file.hidden {
    position: relative;
    text-align: right;
    -moz-opacity: 0;
    filter: alpha(opacity: 0);
    opacity: 0;
    z-index: 2;
}
div.fakefile {
    position: absolute;
    top: 0px;
    left: 0px;
    right: 0;
    width: 370px;
    padding: 0;
    margin: 0;
    z-index: 1;
    line-height: 90%;
}
div.fakefile input {
    margin-bottom: 5px;
    margin-left: 0;
    border: none;
    box-shadow: 0px 0px 2px 1px #ccc;
    padding: 4px;
    width: 241px;
    height: 20px;
}
div.fakefile .fakebtn{
    width: 150px;
    background: #eb5a41;
    z-index: 10;
    font-family: roya-bold;
    border: none;
    padding: 5px 15px;
    font-size: 18px;
    text-align: center;
    cursor: pointer;
    -webkit-transition: all 0.4s ease;
    -moz-transition: all 0.4s ease;
    -o-transition: all 0.4s ease;
    -ms-transition: all 0.4s ease;
    transition: all 0.4s ease;
    display: inline;
    margin-left: 3px;
}
div.fileinputs input[type="file"]:hover + div .fakebtn{
    background: #DA472E;
}

div.fileinputs input[type="file"] {
    opacity: 0;
    position: absolute;
    top: -6px;
    right: 0px;
    z-index: 20;
    width: 102px;
    height: 40px;
    cursor: pointer;
}

The trick is hide the input and customize the label.

enter image description here

HTML:

<div class="inputfile-box">
  <input type="file" id="file" class="inputfile" onchange='uploadFile(this)'>
  <label for="file">
    <span id="file-name" class="file-box"></span>
    <span class="file-button">
      <i class="fa fa-upload" aria-hidden="true"></i>
      Select File
    </span>
  </label>
</div>

CSS:

.inputfile-box {
  position: relative;
}

.inputfile {
  display: none;
}

.container {
  display: inline-block;
  width: 100%;
}

.file-box {
  display: inline-block;
  width: 100%;
  border: 1px solid;
  padding: 5px 0px 5px 5px;
  box-sizing: border-box;
  height: calc(2rem - 2px);
}

.file-button {
  background: red;
  padding: 5px;
  position: absolute;
  border: 1px solid;
  top: 0px;
  right: 0px;
}

JS:

function uploadFile(target) {
    document.getElementById("file-name").innerHTML = target.files[0].name;
}

Here is one way I recently discovered, with a bit of jQuery

HTML Code:

<form action="">
    <input type="file" name="file_upload" style="display:none" id="myFile">

    <a onclick="fileUpload()"> Upload a file </a>
</form>

For the javascript/jQuery part :

<script>
function fileUpload() {
    $("#myFile").click();
}
</script>

In this example, I have put an "anchor" tag to trigger the file upload. You can replace with anything you want, just remember to put the "onclick" attribute with the proper function.

Hope this helps!

P.S. : Do not forget to include jQuery from CDN or any other source
