Replace input file with my own button in the form

Question

Basicly I want to hide the input file and use a button to choose a file in the form.
If I use <label for="input-file">Label</label> when I click the label i get to choose a file, but I would like to be a button or at least to look like a button.
Here is a code sample in JSFiddle :

input[type=file] { display: none; }

<form>
    <input type="file" id="input-file">
    <label for="input-file">
        <button>Button</button>
    </label>
    <input type="submit">
</form>

If I but a button in the label, it acts as a submit button, if I specify its type it does nothing on click.

Is there any way to have upload a file in the form using my button or a button looking control instead of using the input type="file"?
It must be a HTML-CSS solution, no JS or any framework.

EDIT:

This CSS code appears to make the label look like a standard button :

label {
    appearance: button;
    -moz-appearance: button;
    -webkit-appearance: button;
    text-align: center;
    padding: 2px 6px 3px;
    border: 2px outset buttonface;
    font: 13.3333px Arial;
}

Answer 1

You'll achieve this with couple of lines of CSS. Fiddle

input[type="file"] {
    display: none;
}
.custom-file-upload {
    border: 1px solid #ccc;
    display: inline-block;
    padding: 6px 12px;
    cursor: pointer;
}

<label for="file-upload" class="custom-file-upload">
    <i class="fa fa-cloud-upload"></i> Custom Upload
</label>
<input id="file-upload" type="file"/>
