We render the .eml file's content in Mobile View via iframe, email also has one table (not the data table, simple ms word table) in start then long text, but its content is not getting responsive, keeps the table out of screen and shows the scroll bar. Though the same email we see on other app like gmail and outlook looks fine. Kindly refer the screenshot attached. tried many css trick on iframe start, it make the text only responsive but fails on table.
$frame_url=site_url('feuser/mails/frame/'.$mail_id);
<div scroll-y="auto" style="overflow:auto;-webkit-overflow-scrolling:touch">
<iframe frameborder="0" id="iframe" src="<?php echo $frame_url;?>"style="width:100%;height:100%;min-height:600px;"></iframe>
</div>
