Examples

Base #
This HTML Blueprint requires JavaScript to update the label content once a file or files have been selected. You may use your own JavaScript solution, or use Chi's example below.
<input type="file" class="chi-file-input" id="file01" aria-label="Choose file">
<label for="file01">No file chosen</label>
<script>
var inputFiles = document.querySelectorAll('input[type="file"].chi-file-input');
Array.prototype.forEach.call(inputFiles, function(input) {
var label = input.nextElementSibling;
input.addEventListener('change', function(e) {
var fileName = '';
if (this.files && this.files.length > 1) {
fileName = this.files.length + ' files selected';
} else {
fileName = e.target.value.split('\').pop();
}
if (fileName) {
label.innerHTML = fileName;
}
});
});
