Hey akhilz,
I’m not sure what you mean by “its neither centralized nor do i see the full image. have to shrink the screen to see the whole box and that shrinks everything else around it too including the header image etc.”
On mobile and desktop at various sizes your site appears quite functional and responsive.
As far as the height of the columns I don’t see this being something LifterLMS will “fix” in a future release. This is something that, if we implemented, would make theme compatibility even harder than it currently is so our recommendation would be to write CSS or Javascript into your theme or child theme that would automatically handle the element height for you or (better) would be to use uniform image sizes and approximately uniform course titles so that the boxes all match height.
Please let me know if there’s something really obvious I’m missing here as we do want to help resolve your issue but it’s looking pretty good to me at this moment.
Perhaps we’re dealing with a browser / operating system specific issue. Browser & OS specs will help us reproduce and then resolve.
Take care,
