How to put 2 slides next to each other

Didn’t understand your question properly. Do you want to put 2 slides next to each other or 2 slideshow next to each other ?
If you want first one, then use slider type ‘carousel’ or ‘ticker’ and if second one, then you already did it.

I checked your page link and look like there is nothing wrong. you can use like that.

You disabled auto play, excluded next/previous and pagination. So, no way to slide your image.

Thanks for your fast reply. I solved this by myself – I used a table to set 2 slideshows next to each other. But another question: I changed the setting of the overlay to “bottom” but now the line break of the excerpt does not work. Do you have any idea how to solve this?

Use manual excerpt field from post edit screen. Check this link https://www.wpcue.com/wpc-faq/how-can-i-use-html-tags-at-excerpt/

One last question: When I change the size of my browser window (Chrome or Firefox) the size of the title and excerpt also changes. How can I fix this?

There are options to change title,excerpt font size and line height Unit. Change it to ‘px’.

Perfect! Thank you very much for your help (and patience)!!
