File input is used to upload file to a server.

Use our class ".null-form-file", to have simple and clean design.

<form method="get" action="/">

<div class="null-margin-bottom-20">
     <input class="null-form-file" type="file" id="" name="file">
</div><!--End null-margin-bottom-20-->

</form>

Add the below HTML code to have title for file input:

<div class="null-color-main null-font-weight-bold null-margin-bottom-10">Title</div>

<form method="get" action="/">

<div class="null-color-main null-font-weight-bold null-margin-bottom-10">Title</div>

<div class="null-margin-bottom-20">
     <input class="null-form-file" type="file" id="" name="file">
</div><!--End null-margin-bottom-20-->

</form>
