thanks, even tho this can bring more faulty because of components used in the body use the same class-name it was fixed by writing a style in the div-container in sidebar-footer.php
I wrote it like this:
COPY CODE
<div class="col-sm-3" style="width: 100% !important">
<div id="footer-sidebar-1" class="footer-sidebar widget-area" role="complementary">
<?php
if (!function_exists('dynamic_sidebar') || !dynamic_sidebar('footer-1')):
endif;
?>
</div>
</div>
Thanks for your support!
