What I’d like to do is have the slide in coming in from the left ( it is currently coming in from the bottom )
and I would like to remove the view image / symbol and replace it with read more.
I’m not sure what or to look for these changes, I’m guessing it jscript. How can I find out how to change theses things?
I would try to isolate this component and its behaviour, so that you can understand what is causing it to behave as it does.
Start with your website and remove unnecessary content. Then remove unnecessary CSS and JS files until you have just this one element sliding in from the bottom.
At this point you will be in a much better position to affect a change in its behaviour, as you won’t have to randomly change things and hope that they work.
