MAKE EASY SLIDER TO FIT GRID ROW CELL SIZE

Maybe…maybe something that check the size of the first cell (while scaling with the screen) and make the second cell the same size of the first with the content stretched on it. That way should work, I m thinking of a Java snippet but don’t know the code of it and don’t know where to put it.
Waiting for some helps…thanks

Hi Rikard,
you can now access the backend of the page with the same details I gave you last time. The user role I gave you was a subscriber role if you try now I’ve changed it and should work.
I repeat myself again. the problem for me here is not that the element does not work Rikard, instead, I was looking for any suggestion to make it work the way I described above.
Basically, I need to make the slider to display always at the same size (height) of the background image I have on the left-hand side. I need to make the content of both cells display always at the same height of course depending on the screen, so we need to maintain the scalability. If you try to scale the screen now you will see the difference of height between the background image on the left and the slider on the right.
I think (i have been told) this could be done having a javascript that checks the first cell content size and makes the slider the same size.
I have this snippet:
<script>
> $(document).ready(function(){
> $(window).trigger(‘resize’);
> });
>
> $(window).on(‘resize’,function() {
> offsetHMatch();
> });
> function offsetHMatch(){
> $(‘.overlap’).each(function(){
> $(this).find(‘.overlap-large’).height(‘auto’);
> $(this).find(‘.overlap-small’).height(‘auto’);
> var s1 = $(this).find(‘.overlap-large’).height();
> var s2 = $(this).find(‘.overlap-small’).height();
>
> if (s1 >= s2)
> $(this).find(‘.overlap-small’).css(‘height’, s1 + “px”);
> else
> $(this).find(‘.overlap-large’).css(‘height’, s2 + “px”);
> });
> }
</script>
where I should be able to replace these .class names with those used on the element to define the two cells and the div container and should work.
I think I am using the wrong classes because is not working.
I am placing this snippet in the google analytics text code area to try it..maybe this is another issue as well.
Can someone please help me to solve this issue?
Thanks
