I've been attempting to incorporate the custom-file-input feature using bootstrap4 alpha 6, but I'm encountering a blank area after adding it, like this:
<label class="custom-file">
<input type="file" id="file" class="custom-file-input">
<span class="custom-file-control"></span>
</label>
Check out Bootstrap4 file browser documentation for more information.

Do I need to add any specific CSS styles with this implementation?
