One common problem for developers is styling the file input field. Here is one ridiculously simple method that works for IE10+ and all other browsers. Just style the label as you want the input to look.

<pre>
<code class="language-markup">
<label class="my-button-class" style="background-color: green;" for="my-file-selector">
<input id="my-file-selector" type="file" style="display:none;">
Select a File
</label>
