I have a popup box when a user wants to upload csv file. In that popup box, I have a form that uploads a csv file to my database. I use iframe to display the confirmation message everytime the upload is UNSUCCESSFUL because the file needs validation before proceeding. Here's the code:
<form target="list_frame" id="create-list" method="post" enctype="multipart/form-data" action="index.php?view=lists&action=savelist">
<label for="Listname">List Name</label>
<input type="text" name="listname" id="listname" value="" />
<label for="upload">Upload Emails</label>
<input type="file" name="csv" />
<button id="bttn-list">Upload and Save</button>
<iframe name="list_frame" id="list_frame"></iframe>
</form>
What I would want to do now is to assign css to the iframe. I wanna put css on my confirmation message.
