That sounds about right on both! Where did you want to add the link to specifically? Did you want to add a link to the background image? Or just when you set the featured image as a thumbnail?
What I did was use post slider module with one large image on left and then added 3 more smaller ones to the right. Kinda hacked it to make it function like something like Royal Slider
What client wants is to have the large post (left one) be clickable as a link to the post.
I then placed the closing a tag between the last two divs. Like so:
</div>
</a>
</div>
Now you’re going to need to use some custom CSS assigned to the class I added in the a tag above. As the a element in an inline element and therefore, height and widths are ignored. So you’re going to need to try using the code below, but play about with it. As the height and width set in the code below, is the height and width of my post slider yours is likely different.
If you’re trying to recreate the Royal Slider, I think the best course of action would be to use a premium slider plugin such as RoyalSlider or Slider Revolution.
Yes, I agree, probably best to get that slider, but to be honest the client kept having me make changes and I only recently realize that it looks like royal slider. that should do it
