Hi Lili,
We hide the sidebar in small screens (tablet/mobile) to display the content well and beautifully.
You can add login module to the menu, so user can login in small screen
You have to need some adjustment to make your site display correctly with current configuration
1. Diplay sidebar in Medium screen (screen having width higher than 991px but lower than 1200px):
Extensions >> Template Manager >> JA Medicare >> Tab:Layout >> Tab: Responsive layout >> Tab Medium >> http://prntscr.com/4rymc5
2. Display content full-width in tablet screen: edit the file root/templates/ja_medicare/tpls/blocks/ mainbody/one-sidebar-left.php
FROM:
<!-- MAIN CONTENT -->
<div id="t3-content" class="t3-content col-xs-12 col-sm-8 col-sm-push-4 col-md-9 col-md-push-3">
<?php if($this->hasMessage()) : ?>
