How to increase Content Timeline post excerpt on Homepage.

Please navigate to Content Timeline on the left of your Wordpress dashboard. Open any Content Timeline item and click the '+' mark.

Paste as much text as you need into the Item Options excerpt field.

If you need to increase the timeline container height after that, please add this piece of code to Theme Options - Custom CSS section in your admin:

#tl1 .item, #content #tl1 .item { height: 500px !important; }
